keyring

Captures your own auth state from Chrome and stores it locally for your personal AI agents

keyring captures your login sessions (cookies and localStorage) from any website and stores them locally on your computer. Your personal AI agents — built with tools like Playwright, Puppeteer, or Claude — can then load this auth state and act as you without needing to re-authenticate. ── How it works ── 1. Install the extension and run the companion native host (a small Python script). 2. Visit a site you're already logged into and click "Capture this site". 3. keyring saves your session to ~/.keyring/storage-state.json in Playwright- compatible format. 4. Your AI agent loads the file and browses the web as if it were you. ── Two capture modes ── • Whitelist mode — you explicitly choose which sites to capture (default, recommended). • Global mode — capture all sites automatically, with optional per-site exclusions. ── Privacy first ── All captured data stays on your own machine. Nothing is transmitted to any external server. The native host is open-source Python code you can inspect before running. ── Who is this for? ── Developers and power users who build or run personal AI agents and want them to access authenticated web services without sharing passwords or managing tokens manually. ⚠ Note: This extension is intended for capturing your own authentication state for use with your own agents. Do not use it to capture sessions belonging to other people.
