Selected Tools based on Eclipse Theia
Cloud & Desktop
Not sure whether you need a web or desktop version or both?
With Theia you can develop one IDE and run it in a browser or as a native desktop application from a single source.
Extensible
Theia is designed in a modular way to allow extenders and adopters to customize and extend every aspect.
This goes way beyond “just adding extensions”, because Eclipse Theia lets you build fully customized or white-labeled products!
Vendor Neutral
Theia is truly vendor-neutral and developed by a diverse community. Unlike other “open source” projects, Theia is actually hosted at an Open-Source Foundation, protecting it against single-vendor decisions that are against the interest of the community. Learn more here.
Modern Tech
Theia is based on a state-of-the-art web-based technology stack. It provides language support via LSP and DAP. Further, it can host VS Code extensions and provides full terminal access.
