# 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 (186k stars), with browser-use and ragflow close behind. Rankings shift as projects gain stars and ship commits.

19 open-source records, ranked by maintained GitHub adoption; sponsorship never affects the ranking. Browse on the web: https://agentsearchengine.app/best/open-source-autonomous-agents

## FAQ

**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.
