Fork & Attribution Notice:
This project is a customized fork and extension of T3 Code, originally created by Theo Browne (t3.gg) and pingdotgg.
All core architecture, design, and foundational code are the original work of T3 Tools Inc. / pingdotgg under the MIT License. This repository includes custom extensions and community features described below.
- LaTeX Math Rendering: Integrated full LaTeX rendering support for mathematical formulas and notation inside chat messages.

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:
- Codex: install Codex CLI and run
codex login - Claude: install Claude Code and run
claude auth login - Cursor: install Cursor CLI and run
agent login - Grok Build: install Grok Build CLI and run
grok login - OpenCode: install OpenCode and run
opencode auth login - Antigravity: enable it in Settings, then use Install Antigravity and Sign in with Google. No CLI is required.
The easiest way to test T3 Code is to run the server in your terminal (requires Node.js 22.16+, 23.11+, or 24.10+):
npx t3@latestThis will launch T3 Code's backend on your machine as well as the local web app to control your agents.
Tip: Use npx t3@latest --help for the full CLI reference.
Install the latest version of the desktop app from GitHub Releases, or from your favorite package registry:
winget install T3Tools.T3Codebrew install --cask t3-codeStable:
