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.
Note
This is santiago-ramos-02's fork of T3 Code. It follows upstream closely and adds a full Gentle AI integration. Every push to main publishes a new Nightly.
Warning
T3 Code currently supports Codex, Claude, Cursor, Grok Build, OpenCode, Antigravity, and Pi. 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.
Download the latest Nightly for your system from this fork's releases:
| System | File |
|---|---|
| Windows | T3-Code-…-x64.exe |
| macOS, Apple Silicon | T3-Code-…-arm64.dmg |
| macOS, Intel | T3-Code-…-x64.dmg |
| Linux | T3-Code-…-x86_64.AppImage |
The app updates itself to each new Nightly. Windows and macOS may warn that the app is unsigned; choose More info > Run anyway on Windows, or Open from the Finder's context menu on macOS.
To use Gentle AI in T3 Code, install this fork of gentle-ai, which carries the API T3 Code uses:
