# Best Python coding agents

> The open-source coding 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 Skill_Seekers (15k stars), with openevolve and semble close behind. Rankings shift as projects gain stars and ship commits.

## FAQ

**What are the best Python coding 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 coding 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 coding 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.
