## What it is
OpenSumi is a TypeScript framework for building AI-native IDE products, supporting both Electron desktop and web-based (WebIDE) deployments. It includes an MCP client that integrates Model Context Protocol tools for AI-assisted development.

## Use cases
- build a custom IDE product
- create a web-based IDE (WebIDE)
- embed an AI assistant with MCP tools into an editor
- build an AI-native coding environment
- create a desktop code editor with Electron
- customize a VS Code-like IDE framework

## When to choose
- you need a customizable framework to build your own IDE or WebIDE
- you want AI/MCP tool integration built into your editor product
- you need both desktop (Electron) and browser-based editor targets

## When to avoid
- you just need a ready-to-use editor rather than a framework to build one
- you are building a lightweight text editor without IDE features
- your stack is not JavaScript/TypeScript
