MonoCode

MonoCode is an open-source desktop app that gives a single tabbed interface to the coding agents already installed, such as Claude Code and Codex.

MonoCode, from the Mono project at usemono.dev, is a desktop interface for coding agents that are already installed and logged in on a developer's machine. It works with existing subscriptions to Claude Code, Codex, Cursor's CLI, Grok Build, OpenCode, Antigravity, Pi, omp, fx and Hermes Agent, and does not sell tokens of its own. Each tab is an agent session, and a shared composer is used to send prompts, so developers can run and switch between several agents without juggling terminal windows. It is available for Apple Silicon and Intel Macs, Windows and Linux, with .deb, AppImage and .rpm packages. The project is open source on GitHub.
