I'm gradually removing myself from big tech and this month I'm focusing on leaving GitHub, as well as software hosted there. I'm looking for a self-hosted music server that meets these criteria:

• Simple UI - Easy to navigate
• Docker support - For hassle-free deployment
• Runs on Pi3B
• Compatible clients on mobile and desktop
• Robust and well maintained - No buggy releases

Current Option:
The only option I've found but not tried is Funkwhale (GitLab).
Site: https://www.funkwhale.audio/

GitHub-hosted exclusions:
All the other's I've looked at are hosted on GitHub ( Ampache, LMS Lightweight Music Server, Supysonic, Gonic, Airsonic-Advanced, Koel, Jellyfin, Navidrome). So I won't be using those.

Question:
Does anyone know of other options besides Funkwhale, or have you tried Funkwhale? Thanks!

Aside:
Some reasons I'm leaving GitHub:

1. Revealed: Microsoft deepened ties with Israeli military to provide tech support during Gaza war
2. ‘A million calls an hour’: Israel relying on Microsoft cloud for expansive surveillance of Palestinians
3. ‘Use AI or get out…': GitHub CEO warns developers
