How do you host Minecraft servers with unlimited slots?

As you can see on the Minecraft server hosting website, it says buy servers with unlimited slots. I wanted to ask how I can host a Minecraft server myself with unlimited slots, and what equipment I need for it.

Another thing:
I wanted to ask if anyone knows where I can find developers, builders and admins.

You just have to raise the slots in the server.properties file.

You can find team members, for example, at https://minecraft-server.eu/ under https://minecraft-server.eu/forum / forums / search-team members.47 /.

But do you know what kind of equipment I need to make it work?

You only need one server for the slots. Actually, this works with every server. If there's enough RAM, that many players can be on the server at the same time.

Many thanks

Find the server.properties file in the server folder, search for slots and enter a desired number
