Who is a good hoster for minecraft servers? I don't want to host myself. It should have a nice web interface so you should be able to choose a version, upload plugins and co via FTP and have an IP that you can change or add another one. It should have 30 slots and 3-4 GB RAM (or is that not enough for 30 slots + approx 5plugins?) And have good, friendly support. I would pay up to 15 euro a month. Please do not recommend Nitrado, host unlimited.
A root server is the best choice.
Why no host UNlimited? Always had good experiences with them.
https://www.netcup.de/vserver/ Otherwise I would recommend a VServer at netcup but then you have to learn a bit of linux
Nitrado is the best, whether you like it or not
I personally am very satisfied with the vServern at deinserverhost.de.
They also have game servers and I'm sure that they are also very good
But expensive
You want a lot of performance and service for little money. But that doesn't work.
4gb ram for 30 people won't help you, Vanilla will reach its limits.
