Theia - Cloud & desktop IDE framework implemented in TypeScript

Theia is an extensible platform to develop full-fledged multi-language Cloud & Desktop IDE-like products with state-of-the-art web technologies. Theia is entirely written in TypeScript and clearly separates the UI frontend from the backend. The frontend runs in modern browsers or as a Desktop app using Electron with either local or remote (cloud) backends.

Theia provides the VS Code experience in the browser. It integrates a full featured terminal, that reconnects on browser reload keeping the full history. Theia is based on a state-of-the-art web-based technology stack. It provides language support via LSP and DAP.
