Own SMP Minecraft?

I would like to do my own SMP with my friends and I wonder how, does it cost money? How does that even work?

I would be very happy to receive help.

It all depends on what your requirements are.

There are free servers that provide little ram. (It can also lead to decent lags)

Or servers that offer you a lot of ram but then also cost a lot of money.

In addition, the modpacks can differ.

You have to decide for yourself.

Many love greetings The spruce.

Where can you buy them? Are there any websites for that?
