I have never used it but from the website I gather that it's an app (literally, there's a mobile app) which enables you to remotely set up a VPS with a set of services at generic VPS hosting providers like Hetzner or DigitalOcean with the click of a few buttons.

It builds on NixOS which naturally lends itself to abstraction. They have created a pre-made NixOS configuration which configures these services to sensible defaults and provides a few highly abstract options which the user must set themselves. "Enable service xyz", "Enable backups for services a, b, and c".
I assume these are set using a UI; producing a JSON like this. All the generic NixOS config then needs to do is simply consumes the JSON and set the internal options accordingly. But the user doesn't need to care about any of that, the experienced people who maintain this NixOS config do it for them.

I don't know how well it works currently but I absolutely see and love the vision. Imagine being able to deploy all the cloud services you need on your own VPS by creating a few accounts, copy pasting API tokens and then simply tapping sliders and buttons in a mobile app. I can absolutely see that becoming suitable for the masses.
