t3code: Control coding agents from desktop, web, or phone

Added · Updated

Follow and direct coding agents on your computer through web, desktop, and mobile interfaces.

For people already using one of the supported agents.

What it does

T3 Code connects to coding agents that are installed and configured on your computer. Its documentation describes a web app, an Electron desktop app, and companion mobile apps as ways to control those agents. It lists Claude Code, Codex, Cursor, Grok Build, OpenCode, and Google Antigravity as supported providers. The software acts as a control surface for those existing tools; it does not supply the underlying model subscription. After setup, the `t3` command starts its local service and opens the web app.

How to use it

Install and sign in to one supported coding agent, install T3 Code for your system, then run `t3` to start the local service and open its web app.

Common use cases

  • Start a coding agent on a project, then use T3 Code’s interface to follow or direct the agent’s work.
  • Use the documented mobile app to check a coding task that is running on your computer.
  • Install T3 Code as a background service and open its local web app when you want to control the supported agent.

Can I use this?

Desktop, web, and mobile control

Requirements A supported coding agent installed and signed in. The source lists Codex, Claude Code, Cursor, Grok Build, OpenCode, and Antigravity, plus command-line or desktop installation options.

Caveat T3 Code depends on the supported provider’s own installation and account setup; the source says at least one provider must be installed and authenticated.

Worth knowing The source says the project is very early and users should expect bugs. It requires installing and signing in to at least one supported provider. MIT.
