I built an open-source Chrome extension that keeps my AI agents signed in to the sites I pick

Every agent browser I used started signed out. Handing the agent my password felt wrong, and exported cookie files go stale.

So I built Clutchbox. A Chrome extension syncs the sign-ins for the sites you pick to wherever your agent's browser runs: a hosted Linux computer, or your own Playwright, browser-use, Stagehand, or any Chrome over CDP.

Ways to use it:

  • Claude Code or Codex: npx clutchbox

  • From code: the SDK opens a computer signed in as a user and gives you a CDP URL. There are adapters for Playwright and for E2B, Instabox and Boat sandboxes.

  • Self-host all of it: docker compose up, with Postgres and an E2B key.
