Agent Search Engine

Best Python AI agents

The open-source AI agents written in Python, from the Agent Search Engine index — ranked by real maintained adoption (GitHub stars and recent commit activity), never by sponsorship. Every project here is Python-first, self-hostable, and free to run; the trade-off is you host and maintain it yourself. Right now it's led by AutoGPT (187k stars), with langchain and browser-use close behind. Rankings shift as projects gain stars and ship commits.

Frequently asked

What are the best Python AI agents?
The Python projects listed below, ranked by maintained adoption — GitHub stars plus recent commit activity — so you see what's genuinely used and still maintained, not abandoned.
Are these Python AI agents open source and free?
Yes — every project on this page is open source and written primarily in Python. 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.
Why choose Python AI agents specifically?
Staying in your team's primary language — Python — makes self-hosting, extending, and debugging far easier, because you can read and modify the source directly instead of treating it as a black box.
