Open Source AI & Machine Learning Tools

Own your AI stack: models, agents, and the plumbing between

projects 228 combined stars ★ 5.5M refresh nightly
AI tooling is the fastest-moving category on this site, and the most important to self-host: every prompt you send to a hosted API is training data in somebody else's ledger, and every rate limit is a business risk you do not control. The projects below cover the full stack — local model runtimes, agent frameworks, RAG pipelines, vector databases, and the gateways that sit between your app and a dozen model providers. Stars move fast here; check the last-commit date on each card, because a year of silence in AI tooling is a geological era. For anything touching customer data, prefer the AGPL/Apache-licensed projects and read the data-flow docs before wiring them into production.
