# Best open-source browser & computer use

> The open-source browser & computer use 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 UI-TARS-desktop (38k stars), with page-agent and skyvern close behind. Rankings shift as projects gain stars and ship commits.

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