https://www.navidrome.org/ which is a completely new back-end but built to support the Subsonic API.
I took a look at Navidrome before I started using Emby for music, and it just wasn't compelling enough for me to switch to that instead of Emby. Primarily, this is because both Emby and Navirdrome are based entirely on tags, not file structure and tags like Subsonic, so if your collection is not tagged correctly, you'll have difficulty navigating it. Since I had to deal with that limitation anyway, I went with Emby as I was already using it for video. Emby also supports the "composer" tag, which Navidrome did not—at least at the time—so that was another reason to go the Emby route.
Navidrome is also still relatively new—though under active development—so many features you may rely upon in Subsonic will not be available in Navidrome.
Still, it is definitely worth keeping an eye on.
