OpenSumi
by
A framework for quickly building AI native IDE products, supporting Model Context Protocol tools via an MCP server.
OpenSumi Overview
What is OpenSumi about?
OpenSumi provides a modular, extensible platform to create cloud‑based, desktop, or pure‑web IDEs. It bundles core services such as file management, language support, debugging, and UI components, and integrates Model Context Protocol (MCP) tools to enable AI‑driven features.
How to use OpenSumi?
# Install dependencies
$ yarn install
# Initialize the workspace
$ yarn run init
# (Optional) Download default extensions
$ yarn run download-extension
# Start the development server – by default it opens the `tools/workspace` folder
$ yarn run start
# To open a custom workspace:
$ MY_WORKSPACE=/path/to/your/project yarn run start
The project can be run in the browser, as an Electron desktop app, or packaged into a custom IDE product.
Key features of OpenSumi
- AI‑native architecture: built‑in support for MCP tools, enabling intelligent code completion, refactoring, and context‑aware assistance.
- Multi‑environment deployment: same codebase works for web IDEs, Electron desktop clients, and cloud‑hosted IDE services.
- Plugin ecosystem: extensions can be added via the built‑in extension manager or by downloading community plugins.
- TypeScript foundation: strongly typed core APIs make it easy for developers to build custom extensions.
- Rich UI components: ready‑to‑use editor, terminal, file explorer, debugger UI, and more.
- CI/CD ready: GitHub Actions workflows for CI, E2E testing, and coverage badges.
Use cases of OpenSumi
- Custom AI‑enhanced IDEs for enterprises wanting integrated code assistants.
- Educational platforms that provide a browser‑based coding environment with built‑in tutorials.
- Internal developer portals where teams can spin up personalized workspaces quickly.
- Start‑up product MVPs that need a lightweight yet extensible IDE without building one from scratch.
FAQ
Q: Do I need to run an MCP server separately? A: OpenSumi includes client‑side integrations; you can connect to any MCP‑compatible server by configuring the endpoint in the IDE settings.
Q: Can I use OpenSumi with existing VS Code extensions? A: Many VS Code extensions work out of the box thanks to compatible extension APIs, though some may require adaptation.
Q: How do I package a desktop version?
A: Use the opensumi/ide-electron template; it wraps the core with Electron and provides build scripts.
Q: What browsers are supported? A: Modern browsers that support ES2020+ (Chrome, Edge, Firefox, Safari) are fully supported.
Q: Is there a CDN for the static assets?
A: You can host the built dist folder on any static CDN; the framework is framework‑agnostic regarding hosting.

⚡️ Development
$ yarn install
$ yarn run init
$ yarn run download-extension # Optional
$ yarn run start
By default, the tools/workspace folder in the project would be opened, or you can run the project by specifying the directory in the following way:
$ MY_WORKSPACE={local_path} yarn run start
Usually, you may still encounter some system-level environment dependencies. You can visit Development Environment Preparation to see how to install the corresponding environment dependencies.
