I think so? AFAIK It’s basically a static website that need to be updated periodically, with webxdc/xdcget: Submission system for webxdc app stores - Codeberg.org.
Also I had a similar idea of a purely static store website that uses GitHub / Codeberg API:
There used to be
- webxdc/xstore: Rust bot + webxdc app for the xstore@testrun.org bot, allowing to discover and share the latest community submitted webxdc apps. - Codeberg.org
- Everything-apps without platforms - say 'hi' to xstore 😊 - Delta Chat
but now it’s shut down apparently.
