Every game, every server list.

No. Copy a server's address and connect from the game. You only need an account to run a server of your own.

The server is hosted on Nxeon. Servers without it were found on public server lists: Nxeon does not run them.

Servers from public lists are shown as the list had them at the last refresh (a card says when). Player counts are shown only while they are under an hour old; details may be out of date.

By players online by default. You can sort by newest or by name. Nobody can pay for a position.

Some games have no public server list we can use. Their servers appear here when an owner hosts one on Nxeon and lists it.

Host it on Nxeon, then switch on the Public Directory card in the game panel's Settings tab and add a short description. Free Minecraft servers have the same switch in their Manage tab.
