Host a Minecraft server for free: the real options

A free Minecraft server does exist. But "free" always means something else is paying: your computer and your connection, advertising, or your time. The right choice depends on what you want to do: play with friends at the weekend, or open a public server running day and night.

The three ways to pay nothing

	Ideal for	The limit that counts
At home	friends, tests, discovery	the PC must stay on, and the upload speed carries every player
Free host (Aternos and the like)	a small group, a few evenings	queue, shutdown when the server is empty
Free cloud offer	curious people comfortable with Linux	sign-up with a bank card, terms that change

At home: free, but not without constraints

The official server and Paper are free, and a recent PC runs a server for a dozen friends without trouble. The guide Create a Minecraft server details the installation.

Two obstacles always come up:

• Joining the server from outside. You need to open a port on your router, which isn't always possible (shared IP, 4G or 5G connection). Playit.gg gets around the problem for free with a tunnel, and keeps your personal address hidden.
• Availability. The server stops when the PC shuts down or goes to sleep. For friends playing together in the evening, that's acceptable; for a public server, it's a deal-breaker.

Also count the upload speed: 0.15 to 0.2 Mbit/s per player on average, more when everyone explores at the same time.

Free hosts

Aternos is the best known: a simple panel, plugins and modpacks installable in one click, and no fees. The model has its rules, and they aren't hidden:

• The server only runs when it's used. You have to start it from the website, and it stops a few minutes after the last player leaves.
• A queue at startup during peak hours.
• Shared resources, enough for a small group but not for fifty players.
• No domain name of your own: the address carries the host's.

It's perfect to discover, play a season with friends, or test a modpack. For a public server, the automatic shutdown is a problem: a player who finds your server off doesn't come back.

Free cloud offers

Some cloud providers offer "forever free" machines, sometimes with enough memory for a real server. On paper, it's the best deal; in practice:

• signing up requires a bank card and identity verification;
• free machines are often unavailable in the regions you want, and the terms can change or the account can be closed;
• everything is up to you: Linux system, firewall, backups. The guide Install a server on a Linux VPS applies to the letter.

Don't build a community on a machine you can lose overnight. If you use one, keep backups off the machine.

When paying becomes simpler

A Minecraft host costs a few euros a month for about twenty players. The price buys three things free options don't give: a server that's always on, automatic backups, and your own address. The resources and budget calculator gives the memory and price range for your number of players.

The moment to switch to a paid offer is easy to spot: as soon as players you don't know personally come to play, or as soon as you want to list your server. A directory measures uptime: a server that shuts down when nobody plays quickly shows low uptime.

What to pick

• Among friends: at home with Playit.gg, or a free host.
• To test a project: a free host, long enough to validate the idea.
• For a public server: a small paid monthly plan, then better hosting when the community grows.
