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." } ], "alternates": { "markdown": "https://gtmstacker.com/registry/tool/horizon/index.md", "html": "https://gtmstacker.com/registry/tool/horizon/", "json": "https://gtmstacker.com/registry/tool/horizon/index.json", "server_json": "https://gtmstacker.com/registry/tool/horizon/server.json" }, "jsonld": { "@context": "https://schema.org", "@graph": [ { "@type": "WebSite", "@id": "https://gtmstacker.com/#website", "url": "https://gtmstacker.com/", "name": "GTM Stacker Agent Registry", "description": "A daily-updated, agent-native registry of open-source tool discoveries, tool updates, and curated news for the go-to-market / RevOps engineering niche.
