Differences to F-Droid:
- Fully decentralized, an app is bound to a domain name (like in a web browser)
- Every app can be published on SkyDroid, not just open-source apps
- The developer can directly publish his APK with his own signing key
- New apps and updates can be published almost instantly
- Faster syncing
This is really really cool. Let me add support for my app - GitJournal which I still can't publish it on F-Droid as it integrated with Google Play for billing and uses Firebase Analytics (Sadly not Open Source).
I love that with this I'm in control of when the updates are released unlike the F-Droid model.
Edit: On second thought I'll wait for a week and see if this project continues. I really hope it catches on. @redsolver: Do you plan to continue working on this?
