I run my own funkwhale.
But i'm not happy with it.
It has so many bugs and drawbacks.
Searching for remote content does not work well. Sometimes it finds it, sometimes it needs 2, 3 or 5 tries of searching for. Sometimes it does not find it.
Searching is inconsistent.
The UI is also inconsistent. To find what you want to click, you have to search a lot...
It's not possible to modify metadata from already uploaded music. Change mp3-tags locally an upload it again is the way...
You csn not move audios between channrls and libraries.
The permissions-concept is broken.
And the devs want to discuss about how to write about bigs, not about the bugs.
