When it comes to European hosting providers, I think Hetzner is one the best and cheapest options out there. I've been hosting a bunch of Nodejs projects inside docker containers on their servers for several years now and rarely ran into issues.
Big problem tough: you need to setup everything yourself...
They only provide you a blank VPS.
Setting it up and managing your applications can eat up loooooots of time.
That's why I created a PaaS around Hetzner and made it public.

Looking forward for your feedback :-)
