Manage all your AI coding agents from one desktop UI. MonoCode runs Claude Code, Codex, Grok Build, and more using your existing subscriptions.
MonoCode replaces the multi-terminal workflow for developers who run more than one coding agent regularly. All agent sessions are accessible from one window, with a shared input and per-session history.
You use only one coding agent consistently. MonoCode's primary value is unifying multiple agents; if you have one workflow that works, the added UI layer is unnecessary overhead.
The pre-built .dmg makes it fast to install on Apple Silicon. Developers who want to compare Claude Code, Codex, Cursor, and Grok Build side by side can run all four from one interface without juggling terminal windows.
You are on Windows or prefer a browser-based coding environment. MonoCode is a native desktop app with no web version and no Windows build currently available.
MonoCode is MIT licensed and built with Tauri, a Rust-based desktop framework. Developers interested in contributing to open source AI developer tooling can fork the project and submit focused pull requests as outlined in CONTRIBUTING.md.
You need a stable, production-tested codebase to build on. The project launched in late August 2026 and is explicitly at an early, experimental stage.
Developers who use AI coding agents like Claude Code, Codex, or Cursor CLI end up managing multiple terminal sessions, each with its own context and output. There is no shared view across agents, no unified session history, and no way to compare what different agents are producing on the same codebase. Switching between them in a terminal means losing focus and context on every switch.
For developers running two or more coding agents regularly, the operational overhead compounds fast. Each agent has its own login, its own session state, and its own terminal window. The promise of AI-assisted coding gets undercut by the manual work of keeping those sessions organized.
Each coding agent runs in its own session tab. Supported agents: Claude Code, Codex, Cursor, Grok Build, OpenCode, Pi, omp, and fx. Sessions persist their history per tab, so you can switch agents without losing context.
A single text input sends your prompt to whichever agent session is active. You do not need to re-open a terminal or re-type context when switching between agents. All sessions share the same composer UI.
The interface shows code diffs and an editor view inline alongside the agent chat, so you can review changes from the agent without switching to a separate application or terminal window.
A terminal view is integrated into MonoCode alongside the agent chat and editor. You can run commands and see agent output without leaving the desktop application.
MonoCode does not proxy or resell AI inference. It runs agents you have already authenticated, so your model costs go directly to the provider (Anthropic, OpenAI, and others) with no markup or per-session fee.
Cursor is a paid AI-first IDE that bundles a fork of VS Code with integrated AI models, real-time completions, and a chat interface. It is a self-contained product: you install Cursor and it handles model access via a monthly subscription.
MonoCode is not an IDE. It is a desktop session manager that can run Cursor CLI (among other agents) if you have it installed. The two products address different problems. Cursor replaces your code editor and bundles AI capabilities into it. MonoCode adds a GUI layer on top of CLI-based agents you already use.
| Feature | MonoCode | Cursor |
|---|---|---|
| License | MIT | Proprietary |
| Self-hosting | Local desktop app | No |
| AI model access | Uses your existing subscriptions | Cursor subscription required |
| Runs Cursor CLI | Yes | N/A |
| IDE features | No | Yes (VS Code fork) |
| Stage | Early/experimental | Mature |
Choose Cursor when you want a complete AI-integrated coding environment with no setup beyond installing one app. Choose MonoCode when you already have Cursor CLI and other agents installed and want to manage them from a single desktop UI rather than multiple terminal windows.
OpenAI Codex (the CLI coding agent) is a paid tool that requires an OpenAI subscription. MonoCode supports Codex as one of its backends: if you have Codex installed and authenticated, MonoCode can run it in a session tab.
The comparison is less MonoCode vs Codex as competing coding agents and more terminal vs desktop UI for Codex. Codex handles the AI reasoning; MonoCode handles the session interface. Developers who want the Codex experience without staying in a terminal can use MonoCode as the frontend.
| Feature | MonoCode | OpenAI Codex |
|---|---|---|
| License | MIT | Proprietary |
| Role | Desktop UI layer | Coding agent / API |
| Self-hosting | Local desktop app | No |
| AI inference | Via Codex or other agents | OpenAI API |
| Stage | Early/experimental | Generally available |
MonoCode is the better choice when you want a desktop interface for Codex alongside other agents. Codex alone is the right pick if you prefer working in the terminal or only need one coding agent.
Install MonoCode from source on macOS or Linux using Node.js 20 and a current Rust toolchain.
```bash
npm install
npm run tauri dev
```Yes. MonoCode is MIT licensed and free to download, build, and use. It does not charge for AI usage or sell tokens. You pay for the coding agents you connect to it (such as Claude Code or Codex subscriptions), but the MonoCode application itself has no cost.
MonoCode supports Claude Code, Codex, Cursor, Grok Build, OpenCode, Pi, omp, and fx. Each agent must be installed and authenticated separately before MonoCode can run it. The project is early-stage, so supported agent coverage may grow as it matures.
Not yet. The current pre-built release targets macOS (Apple Silicon). Linux users can build from source using Node.js 20 and a Rust toolchain with standard Tauri prerequisites. Windows support is not mentioned in the current README or build documentation.
MonoCode gives each agent session a dedicated tab, a shared composer input, and an integrated diff and editor view. Instead of managing separate terminal windows for each coding agent, you work from one desktop application with all sessions accessible in one place and inline code review built in.
No. The README notes it is very early and bugs should be expected. It is suitable for individual developers experimenting with multiple coding agents, not for teams that need stable, production-tested tooling. The project welcomes small, focused pull requests from contributors.
