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.

Icon Extension


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
