Eclipse Theia

Open-source platform and IDE for cloud and desktop tools

About Eclipse Theia

Eclipse Theia is a modular platform for building custom cloud and desktop IDEs, and the Theia IDE built on it works as a full development environment with VS Code extension compatibility via Open VSX. It is independently developed rather than a fork of VS Code, supports desktop, browser and Docker deployment, and lets vendors create fully tailored tools on its extension architecture.
