Personally I use gonic with the Subsonic API, and Ultrasonic on Android.

Gonic is a super lightweight subsonic API server with a very basic static stats “dashboard”. As so, it’s great for lower end devices. Only problem is that it sometimes fails to pick up the album art is some cases, if that don’t disturb you, then it’s great.

Airsonic (abandonedware) is the best subsonic server in my option. It displays all album arts correctly and is folder based which works much better than Navidrome’s Id tag reader, which is a dumpster fire.

Airsonic is on the heavier side on ram usage, around 1GB. Can probably run just fine on 500mb. Probably around what Jellyfin uses.

Ultrasonic is a great android app. It is just not updated for quite some time now.

I’m also running Jellyfin and I’ll experiment with Finamp. Let’s see if it takes the number one spot from Ultrasonic :)
