jcode Browser Bridge

jcode Browser Bridge connects your browser to jcode — an open-source AI coding agent that runs on your own machine — so the agent can see and operate real pages while it works: open a URL, read the DOM, click and type, take screenshots, and verify what it built. This extension is a companion to the jcode app. It does nothing on its own: you need jcode installed and running locally (https://www.j-code.net). It is the "bring your own browser" backend — instead of launching a throwaway browser, jcode drives the browser you already use, with your logins and sessions. How it works • The extension holds a WebSocket to a jcode server on your own computer (localhost only). • jcode sends DevTools Protocol commands; the extension relays them to the tab it controls and streams events back. • Controlled tabs are placed in a visible "jcode 🔎" tab group, so you always know which tabs the agent is driving. The browser shows its standard "is being debugged" banner while a tab is attached — click Cancel (or Disconnect in the popup) to hand control back at any time. Connecting is one click: open the popup and choose "Auto-connect to jcode." It uses native messaging to find your running jcode app (even on a dynamic port), fetches the local server URL and a pairing token, and connects. You connect once; afterward it reconnects silently. Use Disconnect to revoke the token and detach every tab. Privacy The extension only ever talks to a jcode server on your own machine over loopback (127.0.0.1 / localhost). It sends nothing to us or to any third party. No analytics, no tracking, no ads. Full policy: https://www.j-code.net/privacy Open source: https://github.com/cnjack/jcode
