Ctxfw· tool, 2026-09-25 Ctxfw is an Apache-2.0, in-memory Tree-Sitter AST 'context firewall' — an MCP server that prunes what a coding agent sends to the model, trimming the code context down before it costs tokens. It is on PyPI and self-hostable. It is nascent (2 stars). Its headline '-72.4% token mass' figure is a self-reported, unbenchmarked project claim, not a measured result.
Elmo· tool, 2026-09-25 Elmo is an MIT-licensed, self-hostable platform that tracks how ChatGPT, Claude, Perplexity, Gemini, Copilot, Grok and Google AI Overviews cite or omit your brand — an AEO/GEO citation monitor positioned against Profound, Peec and Otterly. It is established, not a fresh drop: ~13 months old, 362 stars. It is open-core: the self-hostable MIT core is real and active, and a paid Elmo Cloud ($29/mo) and white-label exist alongside it.
oh-my-subagents· tool, 2026-09-25 oh-my-subagents is local subagent orchestration for Codex and Claude — persistent task state, reusable teams, and interruption recovery. Its licensing is split, not simply 'open source': the core orchestration code is MIT, but the Console UI is source-available under the n8n-derived Sustainable Use License v1.0 (internal/non-commercial use only; no commercial redistribution), which is not OSI-open. It has 142 stars.
Sifthound· tool, 2026-09-25 Sifthound is an MIT-licensed, self-hosted web search / extract / crawl / map API for AI agents, exposing a Tavily-compatible interface plus an MCP server. It is brand-new and unproven — created 2026-09-23, last pushed 2026-09-25, 0 stars — so treat it as a fresh drop, not an adopted tool. The value is that it is self-hostable: an owned endpoint you run rather than a paid search API you call.
Skillpack· tool, 2026-09-25 Skillpack is an MIT-licensed, self-hostable, multi-tenant hub to share, version and publish agent skills across MCP clients — an OAuth 2.1 MCP server with a native CLI and a web UI.

Zro CLI· tool, 2026-09-25 Zro CLI is an MIT-licensed command-line tool that runs your existing agent harnesses — Claude Code, Codex, OpenCode, Hermes — against open models, so you can point the coding harness you already use at an open-weight backend. It is self-hostable and early: 2 stars, near-zero traction, created 2026-07-22, last pushed 2026-09-24.
AgentRun· tool, 2026-09-24 AgentRun is a workflow DSL from Parcha-ai — expressed in JSON or TypeScript — for turning repeatable AI-agent work into orchestrated, typed workflows. It ships beta npm packages and is self-hostable under Apache-2.0. It is brand-new: created 2026-09-23, only 20 stars, and explicitly beta, so treat it as an early bet rather than a settled orchestration layer.
Beacon· tool, 2026-09-24 Beacon is an MIT-licensed, local-first memory layer that captures AI-coding-agent sessions across harnesses — Claude Code, Cursor, Codex, OpenCode and others — and serves reusable knowledge over MCP or Agent Skills. It has 1,493 stars, is actively releasing (v1.3.x this week), and self-hosts. Its claim to grade runs into reusable skills is the tool's own, not a verified result.
BoxHaven· tool, 2026-09-24 BoxHaven provides persistent remote dev machines — cloud VMs — for AI agents such as Claude Code and Codex, and is self-hostable. It is licensed AGPL-3.0, a strong/network copyleft license: network use of a modified version triggers source-sharing obligations, which matters for anyone running it as a hosted or SaaS offering. It is nascent (6 stars).
jev-seo· tool, 2026-09-24 jev-seo is an MIT-licensed Rust CLI plus MCP server that runs roughly 50-rule SEO/GEO audits, performs live crawls, computes GEO scores, detects rank drift and enforces CI gates. It is free and self-hostable, and because it exposes an MCP server it can also be driven by agents. It positions as an OSS alternative to paid SEO/GEO auditors with direct GTM utility.
Opaline· tool, 2026-09-24 Opaline is an MIT-licensed CLI that gives PostHog-style session analytics — token cost and usage — for Claude Code and Codex, and is self-hostable. It is a mature project (created February 2026, 298 stars), not a brand-new drop; the recent event is its rename and relaunch from rudel to Opaline. It has been maturing since February.
Repairo· tool, 2026-09-24 Repairo is an Apache-2.0 CLI that detects breaking OpenAPI/API drift and auto-generates AST-transformed, compile-checked fix PRs in TypeScript, Python or Go. It ships an npm package (repairo-cli), CI and a hosted beta, with 184 commits behind it. It carries only 2 stars, so treat it as early and unproven — but it is a real project, not a toy.
Whiteboard· tool, 2026-09-24 Whiteboard is an MIT-licensed desktop canvas where humans and coding agents such as Claude Code collaborate on software design, with AST-aware semantic diffs and decision logging. It is actively shipping — 434 commits, 303 stars, created 2026-08-18, last pushed 2026-09-24. It self-hosts as a desktop app and serves as a shared design surface between developers and their agents.
AWS TOLAP· tool, 2026-09-23 Apache-2.0 protocol from AWS Labs — the Tool-Object Level Access Protocol — that enforces object-level access control (column, row, field) around the tool/function layer so data-access policies travel with the data rather than the agent. It is protocol-agnostic across MCP, LangChain, Bedrock Agents and Semantic Kernel, and ships enforcement SDKs for .NET, Python and TypeScript plus a reference policy server. A legitimate first-party AWS launch, still almost undiscovered (5 stars).
Basta· tool, 2026-09-23 MIT-licensed dead-code detector with a Rust engine that finds unused files, exports, imports and declarations across JavaScript/TypeScript and Python. It is a command-line developer tool for codebase hygiene — you run it against a repo and it reports what is provably unreferenced so it can be safely removed. Rust is the analysis engine, not a target language; the languages it analyzes are JS/TS and Python. Actively maintained (npm v0.3.0 published 2026-09-22).
Tenderness· tool, 2026-09-23 Apache-2.0 Python library that renders synthetic, deterministic documents from text and images via Cairo/Pango to produce labeled datasets for training vision-language and OCR models. It is a rendering library, not a hosted generator app — you call it in code to emit page images with known ground-truth, so the data-prep layer for a document-extraction model is reproducible instead of hand-collected. Early and small (7 stars), for teams needing controlled training data, not a turnkey product.
Buzz· tool, 2026-09-22 Apache-2.0, self-hostable workspace from Block where humans and AI agents collaborate in shared rooms and channels built on a Nostr relay you run yourself. Agents hold their own scoped keys and every event is logged, so a team can hand agents real work — code review, bug triage, workflow orchestration — as permission-controlled, auditable teammates on infrastructure it owns rather than a vendor's.
Drop· tool, 2026-09-22 Apache-2.0 rootless Linux sandbox that runs untrusted programs and agent-generated code in disposable, isolated home directories using user namespaces, with optional gVisor for a stronger boundary. Access is governed by a TOML file and nothing needs root or a container runtime, so you can execute a coding agent's output or a third-party dependency without giving it your real user account.
Strands harness-sdk· tool, 2026-09-22 Apache-2.0 SDK (Python and TypeScript) from the AWS-backed Strands Agents project for building AI-agent harnesses that run in-process, with no hosted control plane. It is model-agnostic — first-class Amazon Bedrock plus Anthropic, OpenAI and Gemini, and local models via Ollama — so an agent you build stays portable across providers and can run entirely on your own hardware instead of being tied to one vendor's runtime.
Google AX· tool, 2026-09-21 Apache-2.0 agentic orchestrator from Google (Go) for running autonomous agent workloads at scale. You declare an agent task in a YAML manifest, its workspace and its gateway, and AX sandboxes the task, wires up the workspace, fences its network, and runs it, on Kubernetes, through a control plane. It integrates with LLM providers you supply, so it handles the isolation and scale-out while you bring the model. Early observers describe it as Kubernetes for agent executions.
HarnessRouter· tool, 2026-09-21 Apache-2.0 abstraction layer, pitched as an OpenRouter for agent harnesses: one API your product calls to run a task, retrieve the result, and switch between coding-agent harnesses (Codex, Claude Code, Hermes and others) without re-implementing each integration. It handles persistent sessions, file handling and streaming behind that single interface. Self-hostable via Docker with your own keys and infrastructure; a managed cloud version exists separately.
motif· tool, 2026-09-21 Apache-2.0 shared-memory system for teams of AI coding agents (TypeScript) that collects agent sessions from Claude Code, Codex and Cursor into one queryable graph of decisions, files and the ties between them, so a team can recall why something was done and stay consistent across tools instead of every session being an island. Self-hostable via Docker or npm with no license key, no feature flags and no limits on members, sessions or projects.
ZCode· tool, 2026-09-21 Apache-2.0 agentic development environment from Z.ai (Zhipu): a TypeScript Electron app that puts the agent conversation at the center, surrounded by a file manager, terminal, Git panel and live browser preview, with desktop, browser and terminal interfaces and an Agent CLI runtime. Z.ai open-sourced the full stack (client, backend, UI, Agent CLI). It is built as the official harness for GLM models and does not ship Claude or GPT support, though the license lets you add integrations.
Cloudflare security-audit-skill· tool, 2026-09-20 MIT coding-agent skill from Cloudflare (JavaScript) that turns an agent into a multi-phase security auditor, built on the assumption the agent will hallucinate, so it makes the agent prove everything. Recon maps the app's trust boundaries, isolated hunter agents attack from separate angles (injection, access control, business logic, crypto), validation agents try to disprove each finding, and the agent that checks a finding is never the one that found it. Output is verified and machine-readable.
ZizkaDB· tool, 2026-09-20 AGPL-3.0 audit-trail database for AI agents (Python) that records every agent decision and session as tamper-evident, checksum-backed logs, tracks the causal lineage between them, and lets you replay a session to see how the agent reached a decision. Each entry carries a checksum that changes if the record is altered, so the trail is verifiable for debugging and compliance. Self-hostable via Docker for free; a managed cloud tier is a separate paid option.
Agent Governance Toolkit· tool, 2026-09-19 MIT public-preview governance stack from Microsoft for putting deterministic controls around autonomous agents. It intercepts tool calls, messages and delegations before execution, evaluates YAML, OPA or Cedar policies, assigns agent identity, records audit decisions, and adds sandboxing, kill switches and MCP security. The Python stack installs locally, with SDKs or adapters for TypeScript, .NET, Rust, Go, OpenAI Agents SDK, LangGraph, CrewAI, AutoGen, Semantic Kernel and other runtimes.
Laya· tool, 2026-09-19 Apache-2.0 local decision engine (Python, open weights) for classifying and scoring text without generating prose. It returns typed choices, ordinal scores and boolean probabilities in one forward pass, with presets for routing, guardrails, moderation and support triage. Three checkpoints cover English, multilingual and task-tuned work. The project reports 33 ms on a T4, but also discloses weak zero-shot performance on the base model and the need for domain calibration.
MiniMax Code· tool, 2026-09-19 MIT source preview of MiniMax's terminal coding agent (TypeScript). The published source covers an interactive TUI, a headless CLI for scripts and CI, and an ACP endpoint for compatible editors. It can use a MiniMax account or a bring-your-own provider through OpenAI-compatible or Anthropic-compatible APIs, including local models. Search, plugins, multimodal tools, MCP and permission controls sit in the same workflow. The repository does not include the separate desktop application's source.
OpenMeter· tool, 2026-09-19 Apache-2.0 monetization infrastructure (Go) for AI, API and usage-based products. It ingests CloudEvents, attributes and aggregates usage, enforces entitlements and credit limits, models plans and dynamic prices, and runs the invoice lifecycle while leaving payment and tax processing to external providers. A Docker Compose quickstart runs locally; production uses OpenMeter API and workers with Kafka, ClickHouse and PostgreSQL. The current v1 releases are beta and can break between upgrades.
Bastionskill· tool, 2026-09-18 MIT skill-poisoning scanner (Python, by Stefano Rizzello) that reads an agent skill before you install it and flags malicious bundled code: hidden network egress, secret theft, hook-install persistence, destructive commands, obfuscation, opaque binaries, and capabilities the SKILL.md never declared. Static analysis only, the skill's code is never run; installs via pip with zero dependencies (3.10+); scans a local skill, a directory, or a remote owner/repo. v0.2.0 returns allow / review / block.
Octop· tool, 2026-09-18 MIT self-hosted AI assistant platform from Tencent Cloud (Python) that runs multi-user, multi-agent for a household or small team from a single instance: one process serves a web dashboard, a CLI, chat channels (Feishu, DingTalk, QQ, Discord, WeCom), an HTTP/SSE/WebSocket API, IDE integration over ACP, and cron automation, all sharing the same agents and data on your own machine. You bring your own LLM provider (OpenAI, DashScope, Ollama and others); nothing core requires a paid Tencent service.
skillbox· tool, 2026-09-18 MIT self-hosted store for AI-agent skills (TypeScript, by Kitze) that keeps your scattered markdown skills versioned in one place and serves them over MCP with client-key authentication, so any agent can pull the skill it needs instead of you copy-pasting instructions between projects. Runs via Docker with no mandatory paid dependency; optional skill-recommendation features can use a paid AI provider but are not required for the core.
Talos· tool, 2026-09-18 MIT self-hosted agent for the terminal and Telegram (Python) built around a deterministic security kernel: before any tool call runs, PolicyKernel.decide() returns ALLOW, NEEDS_HUMAN or DENY, and an approval is a single-use token bound to the exact arguments and valid for 30 seconds. The design principle is 'the model proposes, it never decides', so the LLM cannot execute an effect the kernel has not authorized. Runs locally on your own Claude or Hermes key, with no paid service dependency.
Monid· tool, 2026-09-17 MIT connector framework (TypeScript on Deno) from monid-ai, pitched as 'OpenRouter for agent tools': one interface an agent uses to reach many external tools (search, scraping, people and company enrichment, market data, media generation) instead of hardcoding each vendor. The repo is the open, self-hostable connector layer and execution engine, run locally with keys you bring. A separate hosted platform (monid.ai) sells 2,000+ connectors across 72+ providers on metered billing.
Rowboat· tool, 2026-09-17 Apache-2.0 TypeScript app from Rowboat Labs: a self-hostable multiplayer workspace for teams where each person brings their own AI assistant, and those assistants collaborate across shared Spaces with local knowledge. The Spaces server (Harbor) is open source and self-hostable; the desktop app runs against local models via Ollama or LM Studio, or hosted models with your own key. Optional voice and search integrations (Deepgram, ElevenLabs, Exa) take their own keys.
BrowserSkill· tool, 2026-09-16 MIT-licensed Rust tool from Tencent that connects an AI agent to your real, already-logged-in Chrome instead of a fresh headless one: a local CLI plus a browser extension let the agent borrow one of your open tabs, drive it with your existing cookies and sessions, and then hand control back to you. The agent works inside the auth state you already have, so it can reach logged-in pages without you scripting a login or pasting credentials into a bot.
Bumblebee· tool, 2026-09-16 Apache-2.0 Go tool from Perplexity that inventories the packages and editor extensions installed on a developer machine and checks them against catalogs of known-compromised software, so a supply-chain compromise gets caught on the workstation rather than in production. It is a single static binary with zero non-stdlib dependencies, installed with `go install` and run locally; the compromised-software catalogs ship with it.
Open Code Review· tool, 2026-09-16 Apache-2.0 AI code-review CLI that Alibaba ran internally for ~two years before open-sourcing it: it reads your git diff, runs the changed files through a hybrid deterministic-pipeline + LLM-agent pass with a built-in multi-language ruleset (null-pointer, thread-safety, XSS, SQLi), and posts line-level comments. Bring your own OpenAI- or Anthropic-compatible key, or use delegation mode so a coding agent's own model does the review. Installs from npm.
OpenWiki· tool, 2026-09-16 MIT-licensed TypeScript CLI from LangChain that writes and maintains agent-readable documentation of your codebase, so a coding agent has persistent context instead of re-deriving your repo on every task. It keeps state locally in ~/.openwiki and works against local repositories; it can run through local model backends (Ollama, LM Studio, any OpenAI-compatible endpoint) or hosted providers, so you are not forced onto a paid key.
agentdesktop· tool, 2026-09-15 Open-source visibility and control layer for AI tools across a desktop fleet (Apache-2.0, Rust), backed by Solo.io: it discovers every harness, model, MCP server and skill on a machine (per device and user), applies central policy that reconciles drift, and treats agents as non-human identities issued short-lived credentials scoped to device, user and tool. Runs standalone from local YAML, or in fleet mode via an MDM daemon wired to your identity provider and LLM gateway.
Vibe· tool, 2026-09-15 Open-source, fully-offline transcription desktop app (MIT, Rust) built on OpenAI's Whisper models: transcribe audio and video locally in 90+ languages, detect speakers, translate, and capture your microphone or system audio, with no account and no data leaving the machine. Exports SRT, VTT, TXT, DOCX, PDF and JSON for subtitle and content workflows. Runs on macOS, Windows and Linux, GPU-accelerated when available.
AfterShip/email-verifier· tool, 2026-09-15 MIT-licensed Go library that verifies email addresses without sending mail: syntax checks, MX records, SMTP lookups with catch-all detection, auto-updated disposable-domain lists, role-account detection, typo suggestions and SOCKS5 proxy support. Positions itself as broader-featured than competing Go libraries.
Atomic CRM· tool, 2026-09-15 MIT-licensed full-featured CRM built with React, shadcn-admin-kit and Supabase: contact management, kanban deal pipeline, tasks with reminders, email capture via CC and multi-provider auth (Google, Azure, Keycloak, Auth0). Its fork-first model lets you customize deeply yet pull upstream component updates via the shadcn registry. An open alternative to Attio.
Contentport· tool, 2026-09-15 Open-source (AGPL-3.0) content platform for technical founders: write tweets and threads with AI assistance and schedule them to Twitter/X. Developed in public — the README doubles as a live roadmap. Repo activity has slowed (last push December 2025). An open alternative to Post Bridge.
Frappe Builder· tool, 2026-09-15 MIT-licensed low-code visual website builder for designers and developers: craft and instantly publish sites in the Frappe ecosystem. Its AI site builder, Bob, grounds itself in your site — reading existing pages and reusing your components and theme tokens rather than guessing; frappe.io itself runs on it. An open alternative to Webflow.
jBPM/Apache KIE· tool, 2026-09-15 Apache-2.0 umbrella (Apache Incubator) for integrated business automation: the Drools rule engine (DMN, complex event processing), jBPM workflow engine (BPMN 2.0), OptaPlanner constraint solver and cloud-native Kogito runtime. The oldest open-source BPM lineage — relevant as Camunda 7 reaches EoL and Camunda 8's core went source-available.
LogChimp· tool, 2026-09-15 Self-hostable customer-feedback platform: track user feedback on boards and roadmaps with full brand customization, from your own dashboard. Positions itself as the open-source Canny/ProductBoard alternative. AGPL-3.0 with directory-specific exceptions. An open alternative to Featurebase.
Puck· tool, 2026-09-15 MIT-licensed modular visual editor for React: build custom drag-and-drop page-building experiences from your own React components. It ships as just a React component — works in any React environment including Next.js, with no vendor lock-in and your data staying yours (~13.3k stars).
RefRef· tool, 2026-09-15 Open-source (AGPL-3.0), self-hostable platform for referral and affiliate programs: JavaScript tracking snippet for attribution, customizable rewards with manual or automatic dispersal, referrer and partner portals, fraud monitoring, analytics and a sandbox. Purpose-built for the niche; still alpha — expect breaking changes.
Temporal· tool, 2026-09-15 Durable-execution platform (MIT core) for distributed applications: the runtime persists workflow state, handles intermittent failures and retries failed operations automatically, so business logic survives process crashes. Originated as a fork of Uber's Cadence by its creators; ships a Web UI, CLI and multi-language SDKs. Industry standard for the pattern — but heavy to operate self-hosted.
Wexflow· tool, 2026-09-15 MIT-licensed, cross-platform workflow automation engine (C#): automate file operations, system processes, scripting, networking, email and scheduled batch runs with 100+ built-in activities, a web dashboard, Docker support and 6+ database engines. Approval workflows are first-class; a single-maintainer project.
Ycode· tool, 2026-09-15 MIT-licensed visual no-code website builder and CMS: create and manage sites without code, self-hosted from the open-source project or on the managed cloud. Self-hosting builds on GitHub, Supabase and Vercel. A young open alternative to Webflow.
DeepScrape· tool, 2026-09-14 Open-source web scraper (MIT, TypeScript) that turns pages into agent-readable data: Playwright automation plus a fit-markdown extractor (pruning content filters) for clean Markdown, and an LLM-extraction path (GPT-4o) that returns structured JSON to a schema. Ships a hardened one-command Docker deployment (managed-Redis ready, non-root). A smaller, self-hostable entry in the URL-to-Markdown category alongside Firecrawl, Crawl4AI and browser-use.
HyperFrames· tool, 2026-09-14 Open-source video-as-code framework from HeyGen (Apache-2.0, TypeScript): write HTML, CSS and seekable animations, render a deterministic MP4. No timeline editor. Runs locally via a CLI (Node 22+ and FFmpeg) with an init/lint/preview/render/publish loop, ships 20 agent skills so Claude Code, Cursor or Gemini CLI can drive it, and can generate hundreds of variants from code. Optional HeyGen-hosted cloud and AWS Lambda rendering sit on top of the open core.
Voicebox· tool, 2026-09-14 Open-source, fully-local AI voice studio (MIT, Python + React) from Jamie Pine: clone a voice from a short sample, generate speech across 7 TTS engines and 23 languages, and dictate into any text field with a global hotkey (a Wispr Flow alternative). The GTM hook is one MCP tool call, voicebox.speak, that lets any MCP-aware agent talk back in a voice you cloned. Models, voice data and captures never leave the machine; runs on Apple Silicon (MLX) or CUDA/ROCm/CPU (PyTorch), macOS and Windows.
DeepSeek Harness (dsh)· tool, 2026-09-13 Open-source agent harness from DeepSeek AI (MIT, TypeScript) where everything is a plugin: the model adapter, tool registry, sandbox and agent loop are all swappable, so it runs any model rather than one vendor's. Ships four agent presets, an instant web UI (npx @deepseek-ai/dsh web), OS-level sandboxing (Landlock/Seatbelt/ACL), full MCP support, and a subagent bridge that plugs Claude Code and Codex in as tools. Currently v0.1 (RC7), a developer preview.
OpenShorts· tool, 2026-09-13 Open-source, self-hostable OpusClip alternative (MIT core, Python): turns long videos into vertical 9:16 shorts with AI moment detection, per-scene reframing, face tracking, word-level captions (faster-whisper), and AI voice dubbing. Ships a built-in MCP server (/mcp) and a REST API with completion webhooks so agents can drive it. Self-host free with Docker, or use the managed cloud from $12/mo (the cloud billing dir is source-available under a commercial license, not MIT).
Anomalib· tool, 2026-09-13 Apache-2.0 deep-learning library from the Open Edge Platform (Intel lineage) for visual anomaly detection in images and video: Lightning-based, ready-to-use model implementations from experimentation through deployment, with OpenVINO export for accelerated inference. Claims the largest public collection of anomaly-detection algorithms; the bundled Anomalib Studio web app is pre-release.
Billion Mail· tool, 2026-09-13 Fully self-hosted, open-source (AGPL-3.0) email server and email-marketing platform: newsletters, campaigns and transactional mail on your own server, free of monthly per-subscriber fees. Vendor claims an 8-minute install to first sent email. An open alternative to Mailchimp (~15.6k stars).
Coneshare· tool, 2026-09-13 MIT-licensed, self-hosted alternative to DocSend and virtual datarooms: an access-control, engagement-analytics and workflow layer over files that never leave your existing storage (Nextcloud, Google Drive, Dropbox) — down to page-by-page reading time and video playback. Early-stage, and effectively the only open-source entrant in digital-sales-room reading.
Cossistant· tool, 2026-09-13 Open-source (AGPL-3.0) chat support for the React ecosystem: headless, code-first support components with the API-driven backend behind them, real-time messaging on a modern stack (Turborepo, Bun, Next.js, tRPC). An open alternative to Intercom for SaaS teams that want support UI they fully control.
enthec/webappanalyzer· tool, 2026-09-13 GPL-3.0 database of regex technology fingerprints — HTML, JS variables, headers, cookies, DOM, DNS and meta tags — for detecting what a website runs. The community continuation of Wappalyzer after it went private in August 2023, with an explicit commitment to stay open source. A technographics backbone for prospecting and security tooling.
Frappe CRM· tool, 2026-09-13 Open-source (AGPL-3.0) CRM for modern sales teams — leads, deals and customer interactions, positioned against CRMs it calls too complex with steep pricing. Built-in telephony: make, receive and record calls inside the CRM via Twilio and Exotel. Self-hostable; an open alternative to Attio.
toot· tool, 2026-09-13 ~1323 stars; complements Mastodon.py; OAuth2 login against open Mastodon API; CLI + TUI. Open protocol — no ban/ToS risk. GPL-3.0 copyleft (matters if embedding/redistributing, not for CLI use).
Usertour· tool, 2026-09-13 Open-source in-app product tours, checklists and surveys for product teams — a self-hostable alternative to Userflow and Appcues. Ships an MCP server so AI assistants (Claude Code, Cursor) can generate onboarding flows directly in your project. Dual-licensed: MIT community code plus a separate enterprise license.
zg (zvec-grep)· tool, 2026-09-13 A local-first search tool for people and AI agents that combines ripgrep, BM25, and on-device vector search across code, docs, and data — indexing and search stay on the machine. Auto-configures agents (Claude Code, Codex, OpenCode) and reports fewer tool-calls/tokens on SWE-QA-Bench.
OpenExecutive· tool, 2026-09-13 A self-hostable virtual executive advisory board: one executive voice backed by eight specialist agents (strategy, finance, HR, legal, ops, marketing, product, board comms), with RAG over your own company docs, episodic memory across sessions, and a follow-up scheduler. Ships Slack/email/Telegram/Discord/web/CLI.
AI Engineering Coach· tool, 2026-09-12 Open-source VS Code extension from Microsoft (MIT; also runs in Cursor and Antigravity) that reads your LOCAL AI-coding session logs — GitHub Copilot, Claude Code, Codex CLI, OpenCode, Xcode — and scores your workflow across prompt quality, session hygiene, code review, tool mastery and context management, with 45 anti-pattern detection rules. Read-only, zero telemetry.
litelm· tool, 2026-09-12 Open-source Python library (MIT, 182★) that extracts the core of LiteLLM — model routing, message translation, streaming, tool use and embeddings across 19 providers — into ~2,900 lines with two dependencies (openai, httpx), keeping API compatibility with LiteLLM for drop-in migration.
LLM Wiki· tool, 2026-09-12 Open-source desktop app (GPL-3.0, 19.1k★; Tauri, TypeScript + Rust) that compiles your documents into a persistent, interconnected wiki instead of re-reading them per query like standard RAG: two-step chain-of-thought ingest, a knowledge graph with community detection, cited multi-conversation chat, web clipper, and Obsidian-vault compatibility.
offer-builder· tool, 2026-09-12 Open-source Claude Code skill (MIT) that turns dense market material — industry reports, transcripts, research — into a cold-email-ready offer: it identifies the real problem and its cost, then produces an Offer Sheet with market analysis, value proposition, elevator pitch and a targeting matrix for list building. Deliberately stops before copywriting.
OpenVurp· tool, 2026-09-12 Open-source, local-first multi-agent framework (MIT, Python): create named agents with specific jobs that run on your computer, use real tools, read files, search the web and consult each other, reachable over Telegram, Discord, Slack and WhatsApp — with sandboxing and approval workflows built in, and local models via Ollama or LM Studio.
Reef· tool, 2026-09-12 Open-source infrastructure (Apache-2.0, 1.1k★ within ~10 days of release) for continually self-improving agents: a serve → observe → grow → commit loop that matches production feedback to updates and ships them as versioned changes — either training model weights (via Slime/SGLang) or evolving the agent's harness of prompts, rules and skills.
VoiceStudio· tool, 2026-09-12 Open-source, fully-local voice AI suite (AGPL-3.0, 23.8k★): voice cloning from one reference clip, video dubbing across 646 languages, audiobooks, dictation and transcription, wrapping 14 TTS engines. No account, API key or usage meter for the local workflow — the ElevenLabs alternative that keeps audio on your machine.
Cline (Desktop App)· tool, 2026-09-11 Open-source coding agent (Apache-2.0, 67.8k★) that just shipped a standalone macOS/Windows desktop app positioned for open-weight models: the established bring-your-own-model agent now runs outside the IDE, pairing naturally with local or hosted open-weight LLMs instead of a single vendor's frontier API.
DearAgent· tool, 2026-09-11 Open-source email infrastructure for AI agents (AGPL-3.0, TypeScript, self-hosted on your Cloudflare account): agents create their own addresses, receive mail, wait for verification codes, reply in threads and send — exposed via REST API, webhooks and an MCP server, so an agent can run a real inbox instead of borrowing yours.
Hyper-τ-Bench· tool, 2026-09-11 Open-source benchmark (MIT, Python) from Sierra Research that tests whether an AI coding agent can BUILD a working customer-service agent — not just operate one: the developer agent gets a sandbox with business records, a codebase and a production API, and must design, wire and ship a functioning agent scored against simulated customers.
Raggy· tool, 2026-09-11 Open-source CLI (MIT, Python) for retrieval-augmented Q&A over your local documents: hybrid retrieval (vector + BM25), cross-encoder reranking, and fully local embedding/indexing via Ollama — answer generation can stay local or use a remote API, so private GTM docs never have to leave your machine.
Rune· tool, 2026-09-11 Rune, a fast GPU-rendered keyboard-driven IDE (Go) that folds code, terminals, CLI tools, language intelligence, debugging and AI agents into one multi-workspace environment, just went open source under GPL-3.0 — a polished commercial-grade dev environment moving to a copyleft license.
Portal AI Plugins (Spotify shunt)· tool, 2026-09-11 Open-source Claude Code plugin set (Apache-2.0) from Spotify's Portal platform: the 'shunt' plugin routes I/O-heavy agent work — bulk file reads and boilerplate generation — to cheaper worker models via PreToolUse hooks, cutting Claude token usage by ~90% in Spotify's benchmarks on a Java monorepo.
OpenObserve· tool, 2026-09-10 Open-source, OpenTelemetry-native observability platform (Rust): unified logs, metrics and traces with a dedicated AI/LLM layer that tracks cost, tokens, latency percentiles and error rates across models, plus agent graphs, session traces and evaluation/quality scoring — the monitoring layer for a self-hosted agent stack, an alternative to hosted APM.
Relay· tool, 2026-09-10 Open-source push-to-talk voice interface layer (React/TypeScript) for dense operations dashboards: deterministic intent parsing, a set of UI components and a reusable skill so an AI coding agent can add voice control over analytics views. VERY EARLY.
Security Cards· tool, 2026-09-10 Open-source security-guidance dataset and installable agent skill (Astro site + data): targeted, version-aware security best practices for 80+ widely-used libraries across 13 languages, aimed at coding agents that write functionally-correct-but-insecure code. In the makers' BaxBench eval, wiring it into Claude Code (Opus 4.7) cut the insecure-code rate from 23.9% to 6.6%.
Stroq· tool, 2026-09-10 Open-source local action firewall (TypeScript) for AI coding agents: it intercepts an agent's operations, tracks session state by tainting what the agent has read, and blocks dangerous follow-up actions before they run on your machine — a runtime guardrail with intent/audit that complements install-time scanners.
Cynative· tool, 2026-09-09 Open-source framework (Go) for building your own security agents: ships 45 built-in agents that examine AWS, GCP, Azure, Kubernetes, GitHub and GitLab for privilege escalation, public exposure and supply-chain risks using frontier models. Cloud-security-focused — adjacent to, not core, GTM.
Emailclaw· tool, 2026-09-09 Open-source email AI agent (Java) that uses the email subject line as a project boundary to plan and run multi-step tasks with strict per-workspace isolation — an inbox-native automation surface. VERY EARLY: single-digit stars.
Geiger· tool, 2026-09-09 Open-source, dependency-free CLI (JavaScript) that inventories every AI agent, MCP server, plugin and extension on a machine and reports what each can access — read-only, no install, no telemetry. Agent observability and least-privilege review for a local stack.
MagicVault· tool, 2026-09-09 Open-source secrets layer (Rust) that lets agents use enrolled credentials without ever seeing them: it injects secrets into approved browser fields, HTTP requests or spawned processes while keeping them out of prompts, replies and audit logs. VERY EARLY.
