How to configure Aternos for a Free Minecraft Server #

Playing Minecraft maps with friends is a fantastic experience, but finding the right hosting can be complex. Whether you want to manage a custom map or enjoy the classic Minecraft Vanilla, there is a free and reliable solution for all your multiplayer needs.

In this detailed guide, I will explain to you step by step how to configure and host your Minecraft server for free by relying on Aternos. You will also find out how to upload custom maps and create survival worlds to play in company in total simplicity.

To start your server, the first step is to create an account. You can do it by visiting their official website. Once you create the profile, click the “Play” button located at the bottom right (if you don’t see it immediately, scroll slightly down the page). Always remember that to play safely it is essential to have an authorized copy of the game, which can be purchased from the Minecraft official website.

Just press on “Start”, share the IP address of the server with your friends and start playing. If, instead, you need to install a specific map, keep reading the next section.

How to Load a Custom Map on Aternos #

Custom maps often require less recent versions of Minecraft, as developers take time to update them after each official patch. If the map you have chosen requires a specific edition of the game, you can easily change it by clicking on the green button “Change” in the section dedicated to the software. To see the history of the game versions, you can refer to the Minecraft Wiki Official.

Set the correct version, it’s time to upload. In the left side menu, click on the item “Mondi”. On this page you will have the opportunity to reset the current world or replace it by uploading a new one. To import your custom map, click the “Load” orange button.

The system will ask you if you want to upload a ZIP archive or a folder. Make sure you only upload the folder containing the actual files of the map (such as the level.dat file and region folder), otherwise the server will not be able to read them. The image below illustrates the correct structure of a newly developed map.

After loading, go back to the main dashboard and start the server! Please note that startup may take a few minutes due to the physiological waiting queues of the free service and world loading times. A sound alert will alert you as soon as the server is fully operational. At that point, you and your companions can join the adventure using the IP address shown on the top left in your panel.

Frequently Asked Questions (FAQ) about Aternos and Minecraft #

Is Aternos really free and secure to host a Minecraft server? #

Yes, Aternos is a completely free and secure service. The project is funded through the display of adverts on the platform, allowing players to exploit excellent multiplayer services without having to support any monthly hosting cost. It is the perfect option to play with a small group of friends.

Can I install mod or plugin on my Aternos server? #

Absolutely. Directly from the management panel, Aternos offers an extremely intuitive interface to change the server software type (e.g. Forge, Fabric, Spigot or Paper). This allows you to easily integrate modpacks and custom plugins to enrich your gaming experience.

Why does my Aternos server go offline alone after a while? #

The servers hosted free of charge on Aternos enter automatic shutdown mode if they remain empty (i.e. without active players in the world) for a certain limit of minutes. This measure is used to better manage system resources and make room for other users waiting. To keep it online, make sure there is always at least one player connected to the server.
