Best open-source agent infrastructure

The open-source agent infrastructure in the index — self-hostable, inspectable, and free to run. Ranked by real maintained adoption (GitHub stars and recent commit activity), never by sponsorship. Open source buys you control, privacy, and no vendor lock-in; the trade-off is that you host and maintain it yourself. Right now it's led by daytona (72k stars), with mem0 and cua close behind. Rankings shift as projects gain stars and ship commits.

Frequently asked

What are the best open-source agent infrastructure?
The projects listed below, ranked by maintained adoption — GitHub stars plus recent activity — so you see what's genuinely used and still maintained, not abandoned.
Are open-source agent infrastructure free?
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.
Open-source or commercial agent infrastructure — which should I choose?
Pick open source for control, privacy, and no lock-in when you're happy to host and maintain it; pick a commercial product for a managed, supported experience. You can compare both in the full agent infrastructure category.
