T3 Code
One interface for your coding agents: run Claude Code, Codex, OpenCode and more from a single window.
T3 Code is a graphical interface for AI coding agents running on your machine. It's available as a desktop app, a web app and a mobile app. You need at least one supported agent: OpenCode works for free, while Claude Code, Codex and Cursor require their own accounts. Instead of working in the terminal, you get chats, projects and changes in a clean, organized view. The project is still very young, so expect bugs.
