## About T3 Code

T3 Code, at [t3.codes](<https://t3.codes/>), is an open-source control plane for coding agents, built by Theo and Julius Marminge at T3 Tools. It controls the agents already installed and signed in on your computer. The README lists Claude Code, Codex, Cursor, OpenCode, Grok Build, Antigravity, Kiro, Pi, Muse Code, fx and any ACP agent.

It doesn't resell tokens. You bring your own subscription or credentials for each agent, and you need at least one agent installed and signed in, such as Claude Code or the Codex CLI.

Every agent thread writes to its own branch. One button commits, pushes and opens a GitHub PR with a generated title and body, and you can review the diff inline before pushing. You can also switch models in the middle of a thread.

There is a desktop app for macOS, Windows and Linux, a web app, and iOS and Android apps for controlling agents on your machine from your phone. Install it with curl -fsSL [t3.codes](<https://t3.codes/install.sh>) | sh, with Homebrew using brew install --cask t3-code, with winget using winget install T3Tools.T3Code, or try it without installing by running npx t3@latest. The source is at [github.com](<https://github.com/pingdotgg/t3code>) under the MIT license.

Pricing: T3 Code is free and open source under the MIT license. It does not resell tokens, so you pay only for the agent subscriptions or credentials you already use. Checked November 12, 2026 at https://t3.codes.
