Sorry, to hear it. Theia is an IDE platform and does not target end users but product builders. For end users, we build Gitpod based on Theia to support continious dev environments: https://dev.to/svenefftinge/continuous-dev-environments-the-... You can try to open Theia in Gitpod: https://gitpod.io/#https://github.com/eclipse-theia/theia
Alternatively we provide community supported docker images: https://github.com/theia-ide/theia-apps
