For little fun projects I really like uberspace.de. it's a shared hosting platform, basically you get a user account on one of their Linux servers where you can login and do whatever you want. Price is 10€/month by default but you can go down to 5€ if you're low on cash. They let you pick your own price, just try to be fair. You can't register domains directly from them but your account comes with a yourname.uber.space subdomain and setting up domains you bought somewhere else is super easy too, they also take care of SSL certificates automatically. They also have a lot of documentation about how to run practically any service you'd want there. Here's the page for flask for example: https://lab.uberspace.de/guide_flask/
EDIT: German company run by some nerds that are really helpful if you need something.
tl;dr:
Make of that what you want, but it's the same people as redfish and they couldn't even be fucked to get a new telegram channel or at least think of a company name that's just a tiny little bit more different from the last one. If they're not a continuation of "redfish" then for some reason they tried really hard to make it look like they are. Hüseyin Dogru calling Ukrainians "nazis" and the threat from russia "fictitious" also doesn't really help distinguishing them from russian propaganda.
