MT Code
One command center for your coding agents
Run Claude Code, Codex, Cursor, Grok Build, and OpenCode from your desktop, browser, or phone — free, open source, on your machine.
Agents that use your computer
An agent takes over the browser and desktop UI so you don't have to — clicking, typing, and verifying its own work on screen.
The same engine is open source on its own for Claude Code, Codex and Cursor: Computer Use.
Click, type, and verify on screen
Computer Use lets agents drive browser tabs and desktop UI on your machine — with any provider, not just one vendor's model.
An activity timeline agents can read
Computer History keeps an opt-in record of what you worked on (not screenshots) so agents can pick up context from your day.
Agents coordinate across threads
Reference another thread with #, let sibling threads message each other, and let agents open, park, and close threads themselves.
Up and running in minutes
Install a coding agent
MT Code drives the agents you already subscribe to. Set up at least one CLI: Claude Code, Codex, Cursor, Grok Build, or OpenCode — then sign in to it once from your terminal.
Download and open MT Code
Grab the installer above. macOS: Developer ID signed. Windows: SmartScreen may warn until Azure Trusted Signing is enabled.
Pick a project and start a thread
Point MT Code at a folder, choose your agent, and send the first message. Every thread keeps durable history, checkpoints, and diffs you can restore.
Take it with you
Generate a pairing link in Settings → Connections and open it at mtcode.munimtech.com to control the same agents from any browser or your phone.
Works with your existing subscriptions — MT Code sells nothing and adds no accounts of its own.
Built for people who run agents all day
Picks up where you left off
Threads and agents that were running when the app closed automatically resume on the next launch.
Keeps working until it's done
Set a goal with /goal and the thread keeps iterating until the objective is met — not just until the next reply.
Plugins and skills, cross-harness
Browse and install Codex, Claude Code, and Cursor plugins from a built-in marketplace, and manage skills that work across harnesses.
Talk instead of type
Voice dictation in the composer, powered by OpenAI or Groq transcription.
Knows when to get you
Desktop and browser notifications for approvals, questions, finished work, and failures — so agents run in the background without babysitting.
Desktop, browser, and phone
Desktop
The full app for macOS and Windows. Bundles the server, so it is also the host your other devices connect to.
Browser
mtcode.munimtech.com pairs with the MT Code server on your machine — nothing to install on the device you are holding.
Phone
The T3 Code mobile app (iOS and Android) pairs with any T3-protocol server, including MT Code.
The app is free. Teams pay for the shared fleet.
MT Code runs on your machine and bills nothing for the models — those stay on the subscriptions you already have. What costs money is a workspace other people can join, and computers the whole team can send work to.

MT Code vs T3 Code
MT Code is an open-source fork of T3 Code that tracks upstream nightlies and adds its own features on top. It installs alongside the official app with its own bundle ID and data directory, so you can run both.
