Cookie Sync — Local Chrome → Browserbase Context

Exports cookies from your local Chrome and saves them into a Browserbase persistent context. After syncing, use the browse CLI to open authenticated sessions with that context.

Supports domain filtering (only sync cookies you need) and context reuse (refresh cookies without creating a new context).

Prerequisites

• Chrome (or Chromium, Brave, Edge) with remote debugging enabled
• If your browser build exposes chrome://flags/#allow-remote-debugging, enable it and restart the browser
• Otherwise, launch with --remote-debugging-port=9222 --user-data-dir=/tmp/chrome-debug and set CDP_URL=ws://127.0.0.1:9222
• At least one tab open in Chrome
• Node.js 22+
• Environment variable: BROWSERBASE_API_KEY
