Top two are definitely Syncthing and Navidrome. I really couldn't live without either of these. Organizing music is always a pain. But I use MusicBrainz picard on a desktop or laptop over an sshfs mount to my server. It works quite nicely. I use Calibre-Web, but the whole Calibre system is just plain awful. It's straight out of the 1990s in terms of UI and work flow. I'd like to replace it one day, but I haven't found anything better. I also self-host an instance of Cyberchef[1] which is an incredibly cool web app that does a variety of data conversions and other things. No real point to hosting it I guess, but nice if you're working with private data. [1] https://gchq.github.io/CyberChef/ https://gchq.github.io/CyberChef/
