T3 Code is an "agent harness control surface". It enables control of the agents on your machine with a best-in-class mobile app (iOS, Android), web app and Electron-based desktop app.
Works with your subscriptions on Claude Code, Codex, Cursor, Grok Build, OpenCode, and Google Antigravity. If they're set up on your computer, T3 Code can control them.
Nothing. We built T3 Code because we wanted the best possible development experience with agents. We were inspired by existing solutions like the Codex desktop app, Conductor, Claude Desktop and Cursor Glass, but none met our bar.
We wanted something performant, remote-ready, and truly open. If we ever go the wrong direction, we want you to have everything you need to fork and build the editor that you want.
Warning
T3 Code currently supports Codex, Claude, Cursor, Grok Build, OpenCode, and Antigravity. Install and authenticate at least one provider before use:

Then run t3 to start the server and open the local web app. t3 service install keeps it running in the background, t3 update moves to a newer release, and t3 --help has the full reference.
To try it once without installing, run npx t3@latest instead.
Install the latest version of the desktop app from GitHub Releases, or from your favorite package registry:
