What you need to know before starting

A Minecraft server is a computer that runs the game and lets multiple players connect to the same world at the same time. You have three main routes: rent a server from a hosting company (easiest, costs money monthly), run a server on a computer you already own (free but that computer must stay on), or use Minecraft Realms (Microsoft's official option, middle ground for cost and effort). Most people new to this start with either renting or Realms because they don't tie up your personal machine.

The choice depends on how many players you want, how much control you need, and whether you want to pay. A rented server handles everything for you — you log in, change settings, and play. Running your own server means you control everything but you're responsible for keeping it running and secure. Realms sits in the middle: Microsoft handles the technical side, but you pay per month and have fewer customization options.

Key Takeaways

  • Renting a server from a hosting company is the fastest way to play with friends and requires no technical setup beyond choosing a plan and logging in.
  • Running a server on your own computer is free but keeps that machine tied up and only works when it's powered on and connected to the internet.
  • Minecraft Realms is Microsoft's official subscription option and works on Windows, Mac, and console versions of the game.
  • You need the Java Edition of Minecraft to run your own server; Bedrock Edition (Windows 10/11, console, mobile) uses different server software.
  • Port forwarding is required if you run a server at home, and it exposes your network to security risks if not done carefully.

Renting a server from a hosting company

This is the simplest route for most players. Companies like Nitrado, Aternos, and GameServers rent you space on their computers, handle all the technical work, and let you manage the server through a web panel. You pick how many players you want (usually 2 to 128), choose a monthly plan, and start playing within minutes. The hosting company keeps the server running 24/7 whether you're playing or not, so your friends can log in anytime.

Costs vary widely. Free options like Aternos shut down the server after 30 minutes of no players, then restart it when someone joins — this works for casual groups but adds a wait. Paid plans usually run $3 to $15 per month depending on player count. Most hosting panels let you install mods, change game rules, set the difficulty, and manage who can join without touching any code.

To start: pick a hosting company, choose your plan, create an account, name your server, and wait for it to boot up. You'll get an IP address to share with friends. They add that address to their server list in Minecraft and connect. That's it.

Running a server on your own computer

If you want complete control and don't mind keeping a computer running, you can host the server yourself. Download the server software from minecraft.net (the official launcher), run it on any Windows, Mac, or Linux machine, and players connect through your internet connection. This is free and gives you total control over every setting, but your computer must stay on and connected to the internet the whole time you want people to play.

The basic steps: download the server file, run it once to generate the world and settings files, then edit the server.properties file to change things like difficulty, game mode, and whether PvP is on. Run the server again, and it starts listening for connections. Players need your public IP address (not your home IP — your actual internet-facing address) to connect, which you can find by searching "what is my IP" in a browser.

The catch is port forwarding. Your router blocks outside connections by default for security. You have to log into your router's settings and tell it to forward port 25565 (Minecraft's default) to your computer's local IP address. This opens a hole in your firewall, which is a security risk if not done right. If you're not comfortable with router settings, this route gets complicated fast. Also, if your internet goes down or your computer crashes, everyone gets kicked out.

Using Minecraft Realms

Realms is Microsoft's official subscription service. It works on Java Edition (Windows, Mac, Linux) and Bedrock Edition (Windows 10/11, Xbox, Nintendo Switch, mobile). You create a Realm, invite up to 10 players (Java) or 11 (Bedrock), and Microsoft handles everything — hosting, backups, security, keeping it online. It costs about $8 per month for Java or $8 per month for Bedrock.

The tradeoff is simplicity for flexibility. You can't install mods on Realms (though you can use resource packs and behavior packs on Bedrock). You can't run custom plugins or change advanced server settings. But you also don't have to think about port forwarding, security, or keeping a computer on. Microsoft backs up your world automatically, and if something breaks, you contact Microsoft support instead of troubleshooting alone.

To start: open Minecraft, go to the Realms menu, click Create Realm, pick your subscription plan, and invite players by username. They get a notification and can join immediately. It's the most hands-off option.

Choosing between Java Edition and Bedrock Edition servers

Minecraft has two versions, and they use different server software. Java Edition (the original, runs on Windows, Mac, Linux) uses the official server software from minecraft.net and supports mods, plugins, and custom tools. Bedrock Edition (Windows 10/11, Xbox, Nintendo Switch, mobile, PlayStation) uses different server software and doesn't support mods or plugins the same way.

If you're running your own server or renting from a hosting company, check which version they support. Most hosting companies support both, but the server software is different. Java servers are more flexible and have a bigger modding community. Bedrock servers are simpler but more limited. If your friends play on different versions, you'll need separate servers — they can't play together on the same one.

Setting up port forwarding if you host at home

Port forwarding tells your router to send incoming connections on port 25565 to your computer. Log into your router (usually by typing 192.168.1.1 or 192.168.0.1 into a browser, then entering your admin password — check your router's manual if you don't know it). Find the Port Forwarding section, create a new rule, set the external port to 25565, the internal port to 25565, and the internal IP to your computer's local address (something like 192.168.1.100).

This is a security risk because you're opening your network to the internet. Only do this if you trust the people connecting to your server. Use a strong password for your server, keep your Minecraft server software updated, and consider running it on a separate user account with limited permissions. Never port forward if you don't understand what you're doing — a mistake can expose your whole network.

Common mistakes and how to avoid them

The biggest mistake is confusing your local IP (the address your computer has on your home network) with your public IP (the address your internet provider gives you). Your local IP looks like 192.168.1.100. Your public IP is what you find when you search "what is my IP" online. Players need your public IP to connect from outside your network. If you give them your local IP, it won't work.

Another common problem is forgetting that your public IP can change. If your internet provider assigns you a new one, your friends' connections break. Some hosting companies and home routers let you set up dynamic DNS, which keeps a web address pointed at your IP even when it changes. If you're running a server at home, look into this.

People also underestimate how much bandwidth a server uses. If you're on a capped internet plan, a busy server can eat through your limit fast. Check your plan before inviting a lot of players. Hosting companies don't have this problem because they have unlimited bandwidth.

Frequently Asked Questions

Can I run a server and play on it at the same time?

Yes, but it's not ideal. If you're running the server on your computer and playing on the same machine, you're using resources for both at once, which can cause lag. It works for small groups, but performance suffers. Most people either play on a different computer or use a hosting company.

What's the difference between a server and a realm?

A Realm is Microsoft's managed service — they run it, back it up, and handle security. A server is software you run yourself or rent from a third party. Realms is simpler but less flexible. Servers give you more control but require more work or money.

Do I need to buy Minecraft again to run a server?

No. If you own Minecraft Java Edition, you can download the server software for free from minecraft.net. For Bedrock, you need a Realms subscription or a third-party hosting company. You don't buy the game twice.

How many players can a server handle?

It depends on the server's hardware and your internet connection. A home computer might handle 5 to 10 players comfortably. A rented server can handle 20 to 128 or more depending on the plan. Realms supports up to 10 or 11 players depending on the version.

What happens if my server crashes?

If you're running it at home, everyone gets disconnected and the world stops. You have to restart the server software. If you're renting, the hosting company usually restarts it automatically. Realms backs up your world constantly, so you won't lose progress either way.
