I already know Aternos, but are there any other websites where you can build your own Minecraft servers where you can create multiple servers in one account? Or are there websites where there are more server settings than Aternos? And which websites to create the server recommend you to me otherwise?
Just make a new account for every Aternos server, it's not that hard.
And Aternos is really the best you will ever find on Free Servers. At least I have not found anything better for years. And what does "more attitudes" mean for you? I would not know anything that could not be done with Aternos.
And if you have money, there are of course many better alternatives, but there's nothing in your question.
Although I can't remember completely but I remember that it is quite cumbersome to create a cracked server, since you need to download the console, etc. Of Mojang I believe and then you seperat the server, these servers are VERY unstable, will also advise you to create a new Aternos Acc for each server, the boot time is quite long but better than nothing
