keyring

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.
