What are the best Python agent infrastructure?

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 agent infrastructure 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 agent infrastructure 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.

Best Python agent infrastructure

The open-source agent infrastructure 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 mem0 (61k stars), with cua and Bindu close behind. Rankings shift as projects gain stars and ship commits.
