Brought to you by the creators of Matrix, who have been running the biggest homeserver in the network since 2014. Every homeserver comes with a custom instance of Element.
Service provided by ungleich.ch in their own datacenter in Linthal, Switzerland. They use an old building, second-hand servers, passive cooling and are directly plugged into an on-site hydroelectric power plant!
That service will create your Matrix Homeserver on your domain and server (doesn't matter if it's cloud provider or on an old laptop in the corner of your room), (optional) maintains it (server's system updates, cleanup, security adjustments, tuning, etc.; Matrix Homeserver updates & maintenance) and (optional) provide full-featured email service for your domain.
