Kernel

Cloud browsers for agents — drive real Chromium with Playwright, screenshots, and replays

Give your Ren agents a real browser. Kernel launches sandboxed cloud Chromium sessions in milliseconds and exposes them over MCP: run arbitrary Playwright against a live session, click and type with computer controls, take screenshots, record MP4 replays, persist logged-in profiles, and route through proxies. Ideal for end-to-end testing, QA loops, and any workflow that needs to see and use a web app the way a person would.
