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.

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.
