T3 Code

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, and OpenCode. If they're set up on your computer, T3 Code can control them.

"Wait, what are you selling me?"

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.

Installation

Warning

T3 Code currently supports Codex, Claude, Cursor, Grok Build and OpenCode. Install and authenticate at least one provider before use:

Try it out (install-free)

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@latest

This 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.

Desktop app

Install the latest version of the desktop app from GitHub Releases, or from your favorite package registry:

Windows (winget)

winget install T3Tools.T3Code

macOS (Homebrew)

brew install --cask t3-code

Arch Linux (AUR)

yay -S t3code-bin

Some notes

We are very very early in this project. Expect bugs.

We are (mostly) not accepting contributions yet. Small fixes may be considered. Big features will not be.

T3 Code uses Vite+ so you'll need to install the global vp command-line tool.

T3 Code
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, and OpenCode. If they're set up on your computer, T3 Code can control them.
"Wait, what are you selling me?"
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.
Installation
Warning
T3 Code currently supports Codex, Claude, Cursor, Grok Build and OpenCode. Install and authenticate at least one provider before use:
Try it out (install-free)
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@latest
This 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.
Desktop app
Install the latest version of the desktop app from GitHub Releases, or from your favorite package registry:
Windows (winget)
winget install T3Tools.T3Code
macOS (Homebrew)
brew install --cask t3-code
Arch Linux (AUR)
yay -S t3code-bin
Some notes
We are very very early in this project. Expect bugs.
We are (mostly) not accepting contributions yet. Small fixes may be considered. Big features will not be.
Documentation
Full docs live in docs/. There's no docs site yet.
