T3 Code is a free, open-source desktop and mobile application that lets developers orchestrate multiple AI coding agents like Claude Code and Codex from one interface.
About
T3 Code is an open-source application that serves as a control plane for AI coding agents. It addresses a common frustration for developers who work with multiple AI coding tools: instead of juggling separate terminals and interfaces for each agent, T3 Code brings them together into a single workspace that runs on desktop and mobile.
The application lets developers run agents such as Claude Code, Codex, Antigravity, OpenCode, Cursor, and Grok from one surface. It follows a "bring your own subscription" model, meaning users connect their existing provider subscriptions rather than paying T3 Code for model access. Because the project is open source and hosted on GitHub, where it has earned more than 24,000 stars, users are free to inspect, modify, and fork the entire codebase to suit their own workflows. The project is associated with Theo, the developer known for the T3 Stack ecosystem.

Who It's For
T3 Code is aimed at software engineers and indie developers who already use or are evaluating AI coding agents such as Claude Code or Codex and want a unified interface instead of terminal-only workflows. It suits developers with existing model subscriptions who prefer not to pay a second vendor for access. Mobile-focused developers who want to check on or drive agents from a phone will find the iOS and Android apps useful. It also fits open-source contributors and teams comfortable self-hosting or forking the tool, since the entire codebase is public and modifiable.
