Best open-source autonomous agents
The open-source autonomous agents in the index — self-hostable, inspectable, and free to run. Ranked by real maintained adoption (GitHub stars and recent commit activity), never by sponsorship. Open source buys you control, privacy, and no vendor lock-in; the trade-off is that you host and maintain it yourself. Right now it's led by AutoGPT (187k stars), with browser-use and ragflow close behind. Rankings shift as projects gain stars and ship commits.

Frequently asked
- What are the best open-source autonomous agents?
- The projects listed below, ranked by maintained adoption — GitHub stars plus recent activity — so you see what's genuinely used and still maintained, not abandoned.
- Are open-source autonomous agents free?
- The software is free to run and self-host. You still pay for the infrastructure you run it on and any model or API usage it makes.
- Open-source or commercial autonomous agents — which should I choose?
- Pick open source for control, privacy, and no lock-in when you're happy to host and maintain it; pick a commercial product for a managed, supported experience. You can compare both in the full autonomous agents category.
