# Horizon (self-hosted AI news radar)

> Updated 2026-10-18 · type: tool · category: workflow-automation · status: active · rev 1

Horizon is an MIT, self-hostable AI news radar that fetches, dedups, scores and enriches RSS, HN, Reddit and GitHub into a daily briefing on your own key.

- Open source: yes (MIT)
- Self-hostable: yes
- Pricing: Free and open source (MIT); no paid or hosted tier. Users bring their own LLM API key (OpenAI, Gemini, Claude, DeepSeek) or run local Ollama, so the only cost is the user's own model usage.
- Best for: A founder or lean GTM/ops team that wants its own automated daily briefing of what shipped across RSS, HN, Reddit, Telegram, X and GitHub, self-hosted and keyed to its own LLM account, rather than paying for a hosted curation newsletter.
- Not for: Teams that want a fully managed, zero-setup hosted briefing with an SLA, that cannot bring their own LLM API key, or that are unwilling to run a local, Docker or GitHub Actions deployment.

An MIT-licensed, self-hostable **news radar** that builds your own daily AI-curated briefing: it fetches stories from RSS feeds, Hacker News, Reddit, Telegram, X and GitHub, then dedups, scores, filters and enriches them into a daily briefing in both English and Chinese. The whole pipeline runs on infrastructure you own — locally, in Docker, or on a GitHub Actions cron that publishes the briefing to GitHub Pages — and it is keyed to your own LLM account rather than a hosted service's.

## Provenance

- SPDX **MIT** confirmed via the GitHub API `/license` endpoint — not guessed from a badge.
- Canonical repo is **`Thysrael/Horizon`**, the fork parent of the many "Horizon" / "horizon-*" repos (its 1,628 forks explain the swarm of lookalikes, which copy the "📡 Your own AI-powered news radar" tagline verbatim). Project homepage horizon1123.top is the repo's own site. Scam / name-squat check passed by routing to the origin repo, not the forks.
- Stars **10,716** (GitHub API, 2026-10-18 — current; the viral post said "just crossed 10k", which is accurate), forks 1,628, 3 open issues; created 2026-02-20, last push 2026-10-18 (same day — actively maintained); 10 contributors; not archived.
- Self-hostable three ways: local (`git clone` + `uv sync` / pip), Docker (`docker compose`), or a GitHub Actions cron workflow that publishes a daily briefing to GitHub Pages.
- Free / OSS with **bring-your-own LLM key**: OpenAI, Gemini, Anthropic Claude, DeepSeek, Doubao, MiniMax, or local Ollama. No paid or hosted tier; the only cost is the user's own model usage. A 2026-10-13 commit adds a sponsor (Modelflare) to the support section only — no license or pricing change.
- Surfaced via the 2026-10-18 X pull (viral post by riabcevv). That post returned HTTP 402 and was not fetchable, so all facts were verified against the primary source (GitHub API + README) as untrusted content; no injected instructions were encountered. Curated from the GTM Stacker signal registry (run 2026-10-18-registry-update-01); license, repo, stars, activity and self-hostability independently verified 2026-10-18.

## Why it matters for a GTM stack

Staying current across the tools, launches and releases that touch a GTM stack is a real tax, and the usual answer is a paid curation newsletter — someone else's editorial, on someone else's cadence, that you cannot tune. Horizon is the own-your-stack version: a pipeline that pulls from the sources you choose (RSS, HN, Reddit, Telegram, X, GitHub), scores and dedups them, and enriches a daily briefing with the model you already pay for. For a founder or lean ops team, that means a briefing shaped to your own filters, running on your own key, published wherever you host it. The honest read: the name is heavily forked, so you must install from the canonical `Thysrael/Horizon`, and "free" means the tool, not the LLM calls — you bring and pay for your own model. What is verified is what governs adoption: MIT from the license endpoint, three self-host paths, and a repo that was pushed the same day it was checked.
