Love Roon. I also have Navidrome in my server but found out a docker image of RoonServer and my gosh, I love it. I need a webapp to control it from my Linux desktop, otherwise, perfect (and expensive).

If you want, you can self host an Navidrome instance and listen to your music in your devices with Substreamer (in fact, any subsonic compatible client works with navidrome).
