Just wonking about on the internet… oh look, a bee.
When it’s running in server mode it provides a similar UI too when it’s a client, except now you can browse the snapshots/policies of each client that uses it.

My vote goes to Kopia.
I just bought an actual domain and use that 😅
As an added bonus, letsencrypt works with no effort.
