# Best Python voice agents

> The open-source voice 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 bailing (1.7k stars), with CyberVerse and Patter close behind. Rankings shift as projects gain stars and ship commits.

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

## FAQ

**What are the best Python voice 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 voice 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 voice 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.
