Some weeks back apkupdater stopped being able to download/upgrade/install from apkpure, but now a days I see issues with apkmirror as well (I see way less apps when searching for them). There was an initial issue about not being able to install from apkpure, but it seems more than that.

Agreed there's aurora store, but to be honest, I pretty much prefer avoiding the Google Play store at all, and I haven't found an issue with apkpure.

There was apkgrabber, but it was not working since so long, and finally it got archived on github.

Is there some FLOSS app similar to apkupdater, other than aurora store?

Anyone experiencing issues with it? Issues are not meant to be status reports once filed, but it seems not many have even noticed about the referred issue.
