T3 Code

T3 Code is an open-source desktop app that runs coding agents such as Claude Code, Codex and Cursor from one interface. It is mainly used to manage agent threads, diffs and pull requests across machines and devices.

Who it's for

Best for

  • Developers juggling Claude Code, Codex and other agents in one place
  • Power users running agents on remote machines from a phone

Not for

  • Developers wanting a full IDE with editing built in

Features

  • Multi-agent control plane

    Orchestrates Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok from one surface.

  • Existing subscriptions reused

    Each harness signs in with its existing login, such as claude auth login or codex login, so an existing paid plan is reused.

  • MIT-licensed source

    The whole app is MIT licensed, with source on GitHub open to browsing and forking.

  • Desktop and mobile apps

    A macOS download is offered alongside other platforms, plus iOS and Android apps.

  • Diffs and pull requests

    Agent work can be reviewed as a diff and opened as a pull request from the app.

What users say

Pros

  • Claude Code, Codex and other harnesses run from one interface, with threads continuing across providers.
  • Desktop, web and phone access make it practical to keep agents working while away from the main machine.
  • Orchestration passes work between threads and models, splitting tasks across cheaper sub-agents.
  • Free, MIT-licensed code makes forking and adding custom features straightforward.
  • Sessions stay persistent on a remote Linux machine, with diffs viewable from a Mac.

Cons

  • Basic UX gaps remain: a fixed-width file tree cuts off filenames and tiny tabs invite misclicks.
  • New threads default to full access, a setting that needs changing first.
  • The app is not an IDE, so a separate editor stays necessary for hands-on coding.
  • The mobile app UI is weak, and voice recording fails on mobile.
  • Self-hosting in containers takes extra work because no official Docker image exists.
