Best Python AI agents
The 158 open-source AI agents written in Python in this index, ordered by recorded GitHub star count, never by sponsorship. Stars are repository-interest signals, not performance or maintenance guarantees. Hermes Agent leads the set at 253,000 GitHub stars, and 129 of the 158 have a recorded repository push in the last 90 days. These records have Python as their primary repository language and recognized open-source software licenses recorded in this index; check the current licenses, deployment requirements, and model or API costs. Right now it's led by Hermes Agent (253k stars), with Langflow and langchain following. Order follows the recorded star counts; repository activity is shown separately.

Frequently asked
- What are the best Python AI agents?
- By recorded GitHub star count, Hermes Agent, Langflow and langchain lead the Python AI agents in this index of 158. The full list is below; star count does not prove suitability or continued maintenance. Sponsorship does not affect its order.
- Are these Python AI agents open source and free?
- These records have recognized open-source software licenses recorded and are written primarily in Python in this index. MIT is the most common licence here, on 85 of 158, across 7 licences in total. Check each license and deployment requirements. Hosting, model, API, and managed-service costs may apply.
- Why choose Python AI agents specifically?
- Staying in your team's primary language — Python — can help your team inspect and modify code it understands. Repository language does not establish supported user languages, SDKs or an offline deployment. 129 of these 158 have a recorded push within 90 days. A quiet repository alone does not establish whether the project is complete, supported or abandoned.
