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, and Google Antigravity. 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, 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.
Command line
1 | curl -fsSL https://t3.codes/install.sh | sh |
On Windows, in PowerShell:
1 | 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
instead.
Desktop app
Install the latest version of the desktop app from GitHub Releases, or from your favorite package registry:
Windows (winget
)
1 | winget install T3Tools.T3Code |
Windows (scoop
)
1 | scoop install extras/t3code |
macOS (Homebrew)
1 | brew install --cask t3-code |
Debian, Ubuntu (.deb
)
Download the .deb
