I've self-hosted the original Firefox syncserver[0] for a couple of years now. It's a now unmaintained Python 2 + gunicorn web app.
It still uses the Firefox identities service, since I haven't bothered to try setting that one up myself. That means I need a Firefox/Mozilla account even with a self-hosted sync server, which isn't ideal.
Note that Mozilla do provide a script to delete all your data from their servers[1], in case you were using Firefox sync before going self-hosted.
I originally went through the setup instructions manually. Now I've created a Nix package[2] and NixOS module for it[3], which was an adventure by itself. I can now easily reproduce the setup, which I did while migrating my webserver to a different provider.
As for why I didn't try syncstorage-rs, it's rather petty, but the old syncserver was working well for me, and it doesn't yet support SQLite.

Have you considered upstreaming the package and module to nixpkgs? It would be awesome to have those one line of config away for all nixpkgs users.
- The new replacement package, syncserver-rs, has already been added to Nixpkgs, along with a NixOS module [0]
- Python 2 and the package itself are no longer supported, meaning...
- support in Nixpkgs is pretty rough - dependencies have been updated such that they no longer support Python 2, or have been removed outright, meaning...
- syncserver has already been removed from Nixpkgs
- in order to avoid the problem of unsupported dependencies, I delegated dependency resolution to a community project, poetry2nix[1]. Even so, it was a nightmare to get working, lots of hacks and workarounds were needed
Of course, my repo is public, so anyone is welcome to use the Flake within. If they do, I'd suggest dropping me a line so I don't do anything drastic to the package or module.
