MonoCode
MonoCode is an open-source desktop application built with Tauri that provides a unified graphical interface for multiple AI coding agents. It organizes each agent session as a tab within a single window, allowing developers to run and switch between Claude Code, Codex, Cursor, Grok Build, OpenCode, Pi, omp, and fx without leaving the desktop environment. The application leverages the user's existing subscriptions to these services, meaning no additional API costs or separate logins are required beyond what the user already has. It is designed for macOS, Linux, and Windows, making it a cross-platform solution for developers who work with multiple AI assistants. The core value of MonoCode lies in its ability to consolidate the growing ecosystem of coding agents into a single, manageable interface. Instead of juggling multiple terminal windows or switching between different applications, developers can keep all their agent sessions in one place, each in its own tab. This is particularly useful for comparing outputs, running parallel tasks, or simply keeping a clean workspace. The use of Tauri ensures a lightweight and efficient desktop app that does not consume excessive system resources compared to Electron-based alternatives. As an open-source project, MonoCode invites community contributions and customization. It is positioned as a GUI layer on top of existing agent CLIs, so it does not replace the agents themselves but rather enhances their usability. The project is still evolving, and users can expect ongoing improvements and support for additional agents as the ecosystem grows.

Problem solved
MonoCode solves the problem of managing multiple AI coding agents by providing a tabbed desktop interface that runs them side by side, eliminating the need to switch between separate terminal windows or applications.
Use cases
- Run Claude Code sessions in a dedicated tab
- Switch between Codex and Cursor without leaving the desktop
- Compare outputs from different coding agents on the same task
- Manage multiple agent sessions for parallel development tasks
- Use existing subscriptions to coding agents in a unified UI
- Work across macOS, Linux, and Windows with the same tool
- Keep a clean workspace by consolidating agent terminals into one window
Audience
- Developers
- Hobbyists
- Startups
