A command-line browser automation tool designed for use by AI agents.

Verified 2h ago### Bug Fixes
- Fixed **auth vault login** to pick usable controls when hidden duplicates exist, and to bind credential entry to the selected field so replaced fields or redirected focus are rejected before submitting (#2014)
- Fixed **chat mode** to allow `webmcp`, `skills`, and other top-level browser commands, so the model uses page WebMCP tools instead of falling back to `eval` (#2015)
- Fixed **Kernel profiles** so `KERNEL_PROFILE_NAME` sessions send the profile as an object instead of failing with a 400, and added `KERNEL_PROFILE_SAVE_CHANGES` to opt into saving changes back (#2004)
- Fixed **Chrome freezing after launch** by draining its stderr for the browser's lifetime, so a full log pipe no longer blocks the browser (#2003)
- Fixed **Browser Use** by switching to Cloud V4, which creates, attaches to, and stops the same browser with bounded timeouts (#1879)
- Fixed **Vercel Sandbox shared memory detection** by measuring `/dev/shm` capacity and adding `--disable-dev-shm-usage` below 256 MiB, so Chrome no longer terminates renderers on the undersized mount (#1890)
### Improvements
- Upgraded the **eve integration** from eve 0.47.3 to 0.57.0, so apps on eve 0.50 and later
