T3 Code offers a cross-platform interface for local coding agents
According to the project README, T3 Code is an “agent harness control surface” for controlling coding agents configured on a user’s computer. It describes iOS and Android apps, a web app, and an Electron-based desktop app, with claimed support for Claude Code, Codex, Cursor, Grok Build, OpenCode, and Google Antigravity. The developers say the project is very early, that users should expect bugs, and that they are mostly not accepting contributions.
The README describes a unified interface for controlling locally configured coding agents across mobile, web, and desktop clients. However, the report is based on the project’s own documentation, and the developers explicitly describe the project as very early-stage.
T3 Code
T3 Code is an "agent harness control surface". It enables control of the agents on your machine with a best-in-class mobile app (iOS, Android), web app and Electron-based desktop app.
Works with your subscriptions on Claude Code, Codex, Cursor, Grok Build, OpenCode, and Google Antigravity. If they're set up on your computer, T3 Code can control them.
"Wait, what are you selling me?"
Nothing. We built T3 Code because we wanted the best possible development experience with agents. We were inspired by existing solutions like the Codex desktop app, Conductor, Claude Desktop and Cursor Glass, but none met our bar.
