What it is

T3 Code is described by its authors as an "agent harness control surface": it lets you control AI coding agents installed on your machine, such as Claude Code, Codex, Cursor, Grok Build, OpenCode, and Google Antigravity. It can be used through a desktop app, a web app, or mobile apps for iOS and Android. The README says it works with your existing subscriptions, as long as the agents are set up on your computer.

  • Start the local server with the t3 command and control agents through the local web app
  • Run T3 Code as a background service so it keeps running
  • Connect to agents from a phone or another computer (the README links a remote access guide)
  • Connect outside agents over MCP, according to the documentation index

Great for

  • Developers who already use one or more supported coding agents and want a single interface for them
  • People who want to control their agents from a phone or another machine
  • Users who want an MIT-licensed tool they can read, fork, and modify
  • Developers comfortable with a very early project that may have bugs

Not ideal for

  • People who do not use any of the listed agent tools, since at least one provider must be installed and logged in first
  • Teams who need stable software or contributions accepted, because the README says the project is very early and is mostly not accepting contributions yet
  • Users who need full documentation, since the README says there is no docs site yet

    Install desktop app on macOS with Homebrew

    brew install --cask t3-code
  2. 2

    Run it

    • Install and log in to at least one supported agent tool, such as running codex login or claude auth login
    • Install T3 Code using one of the install commands
    • Run t3 to start the server and open the local web app
    • Optionally run t3 service install to keep it running in the background
