Syncthing seems way too manual for my taste. I want something which i can easily provision with Ansible and which does not run a management ui. I want everything to be in config files which can be provisioned. It might be possible to run Syncthing like this but last time I checked it was poorly documented.

I have also tried Unison, which is closer to my needs, but it has its own issues like having to be compiled with the same version of Ocaml on all servers.
