Eclipse Theia, an IDE platform for building multi-language desktop and web-based IDEs from the same codebase, has reached version 1.0 status.
The Eclipse Foundation describes Theia as a true open source answer to Microsofts popular Visual Studio Code editor. Theia even runs Visual Studio Code extensions for capabilities such as Python and Java language support. However, thus far Theia is intended to be fitted into third-party products. An end-user version is on the roadmap for release later this year.
