It’s a project by among others Q (@q@glauca.space on mastodon), a well known hacker in the CCC sphere of influence. She held some very interesting talks and I use another Project of hers (zügli.app, extracting info from train tickets) every day.

I wanted to use it myself but in the end it was simply cheaper to register my domain elsewhere.

Trustworthy: I think so

Customer support if something breaks: They seem quite busy and this is more of a side project, so be patient

Hate to be that guy, but presumably she?
