Kernel provides cloud browsers, computer controls, Playwright execution, session replays, and persistent browser profiles for building browser-based agents and automations.

Use it from your agent

One ClawLink account serves every agent you run. Pick the guide for yours, or connect Kernel once and call the same tools from all of them.

Setup

Connect Kernel through ClawLink's hosted setup.

Auth: Paste one API key. The credential stays on the ClawLink server; your agent holds only a ClawLink key you can revoke.
Where: the ClawLink dashboard, or ask your agent to connect it.
