What is it?
T3 Code is an agent harness control surface that lets you drive the coding agents already installed on your machine. It connects to Claude Code, Codex, Cursor, Grok Build, OpenCode and Google Antigravity, using the subscriptions and logins you have already set up, so no separate account is needed to start.
The project ships as a command-line server started with `t3`, which serves a local web app, as an Electron desktop app, and as iOS and Android mobile apps. A background service mode and remote access let you reach agents running on another machine from a phone or browser.
The codebase is TypeScript under the MIT license, and the project is in an early stage, so the maintainers expect bugs. Outside contributions are limited to small fixes for now.
Key features
- 01Controls Claude Code, Codex, Cursor, Grok Build, OpenCode and Antigravity agents from one interface.
- 02Runs as a local command-line server with a web app.
- 03Offers an Electron desktop app for Windows, macOS and Linux.
- 04Provides iOS and Android apps for remote control.
- 05Can run as a background service and be accessed remotely.
Use cases
- Monitoring and steering coding agents running on a development machine from a phone.
- Using several agent CLIs side by side from a single desktop window.
- Running an agent on a home or office server and accessing it from another device.
Quick start
- 1
Install the command line tool (macOS/Linux)
curl -fsSL https://t3.codes/install.sh | sh - 2
Start the server and open the local web app
t3
Things to know
- Very early stage, so expect bugs.
- Needs at least one agent provider (such as Codex, Claude Code or Cursor) installed and logged in on your machine first.
- Mostly not accepting outside contributions yet; only small fixes may be considered.
