Introduction

Description shown in its original language (English).

T3 Code is an open-source control plane for coding agents, with one interface for Claude Code, Codex, OpenCode, Cursor, Grok, and other coding harnesses. It uses the subscriptions and credentials users already have, supports switching models mid-thread, and gives each thread its own branch. Inline diff review and GitHub actions for commits and pull requests are built in, and the MIT-licensed code can be forked and self-hosted.
