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, OpenCode, Google Antigravity, and fx. 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, OpenCode, Antigravity, and fx. 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.
 - fx: install fx and run fx login on the machine running the T3 Code server (setup guide)

 Command line

bash
curl -fsSL https://t3.codes/install.sh | sh


On Windows, in PowerShell:

powershell
irm https://t3.codes/install.ps1 | iex


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. It offers to install the t3 command for you.

 Desktop app

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

 Windows (winget)

bash
winget install T3Tools.T3Code


 Windows (scoop)

bash
scoop install extras/t3code


 macOS (Homebrew)

bash
brew install --cask t3-code


 Debian, Ubuntu (.deb)

Download the .deb from GitHub Releases, then:

bash
sudo apt install ./T3-Code-.deb


 Arch Linux (AUR)

Stable:

bash
yay -S t3code-bin


Nightly:

bash
yay -S t3code-nightly-bin


The AUR packaging is maintained in this repository under packaging/aur.

 Nix (nixpkgs)

bash
nix profile add github:NixOS/nixpkgs/nixos-unstablet3code


The package is maintained in nixpkgs
and includes the desktop app (t3code-desktop) and the t3 command.
See Nix installation for NixOS configuration and updates.
