About

The Eclipse IDE is a modern and open IDE for cloud and desktop. The Theia IDE is based on the Theia platform. The Theia IDE is available as a downloadable desktop application. You can also try the latest version of the Theia IDE online. The online test version is limited to 30 minutes per session and hosted via Theia.cloud. Finally, we provide an experimental Docker image for hosting the Theia IDE online.

The Eclipse Theia IDE also serves as a template for building desktop-based products based on the Eclipse Theia platform, as well as to showcase Eclipse Theia capabilities. It is made up of a subset of existing Eclipse Theia features and extensions. Documentation is available to help you customize and build your own Eclipse Theia-based product.

Showing 8 of 14. Source: NVD, updated 3h ago. Patch status is best-effort: NVD's fix version is compared against the latest version in winget, but the two version formats don't always align. Confirm with the vendor advisory before treating any specific build as safe.
