If you want to enjoy Minecraft version 1.21 with mods and play with friends, hosting your own server is a great way to do it. You don’t need to be a tech expert to set up a 1.21 Minecraft server with mods. This guide will walk you through every step using very simple language. Whether you’re looking for a paid host, a free host, or want to do everything yourself on your computer, we will explain all the possible ways. Mods make Minecraft even more exciting, and with version 1.21 being one of the most awaited updates, hosting a server with mods is more popular than ever.

Let’s break down the process and cover everything you need to know about 1.21 Minecraft server host with mods — including what tools you need, how to install mods, and where to host your server.

What Does It Mean to Host a Minecraft Server With Mods?

Hosting a Minecraft server means that your computer or a company’s computer will run the world that you and your friends can join. When you add mods, you are customizing that world with new items, creatures, blocks, or gameplay changes. Mods are made by players and fans, and they can completely change how Minecraft feels.

A modded server lets all players enjoy these changes together. But it also means that every player must have the same mods installed on their computer as the server. That’s why choosing the right method to host your server is important.

Minecraft Version 1.21: What’s Special About It?

Minecraft 1.21 introduces new features like new mobs, blocks, mechanics, and maybe even new structures. Because of this, mod creators are updating their mods to work with this version. If you want to enjoy 1.21 with mods, make sure that the mods you choose are already updated to this version.

What You Need Before Hosting a Modded Minecraft Server

Before we jump into how to host the server, here’s a short list of things you will need:

A copy of Minecraft Java Edition
A computer with enough RAM (at least 4GB free for the server)
Mods that are compatible with version 1.21
Forge or Fabric (mod loaders)
Server software (modded version of the Minecraft server)
Internet connection with decent upload speed
Optional: A hosting service (paid or free)

Now let’s explore different ways you can host a Minecraft 1.21 server with mods.

Method 1: Hosting a Modded Minecraft 1.21 Server on Your Own Computer (Free Option)

This method is completely free but depends on your computer and internet connection. It’s a good way to test things or play with a few friends.

Step 1: Install Java

Minecraft runs on Java. You need to install the latest version of Java 17 or later.

Search for “Java 17 download”.
Download and install it.

Step 2: Download Forge or Fabric for 1.21

Forge is the most popular mod loader.

Visit the Forge website.
Download the Installer for Minecraft 1.21.
Run the installer and choose Install Server.
Choose a folder to install it into.

Step 3: Prepare the Server Folder

Once Forge installs the server files:

Place all your 1.21 mods into the mods folder.
Run the forge-1.21.jar file to start the server.
A file called eula.txt will appear. Open it and change false to true.
Run the file again to fully start the server.

Step 4: Share Your IP

To let friends join:

Share your IP address.
They must also install the same Forge version and mods as you.
They connect by clicking Multiplayer > Direct Connect > Your IP.

If you want to keep the server running all the time or don’t want to deal with internet setup, consider a host.

Method 2: Using a Paid Host for 1.21 Minecraft Server With Mods (Easy and Reliable)

Many companies offer Minecraft server hosting. They handle everything — your server is always online, and some even offer one-click mod installations.

These are popular hosts that support 1.21 modded servers:

Select Minecraft Java Edition > Modded (Forge).
Choose version 1.21.
Use the control panel to upload mods into the mods folder.
Restart the server.

Now your server is live and ready for friends.

Method 3: Free Hosting Options for 1.21 Minecraft Server With Mods (Limited Features)

Free Minecraft server hosting is possible but comes with limits such as lag, timeouts, and fewer customization options. It’s okay for small games.

Common Mistakes to Avoid

Wrong Mod Versions: All mods must match the server version (1.21). If even one is wrong, the server might crash.
Too Many Mods: More mods need more RAM. Start small and test.
Players Without Mods: Make sure everyone has the same mods.
Not Enough RAM: If the server crashes often, you might need to upgrade your RAM or hosting plan.

Can I Host a Minecraft Server With Mods?

Yes, anyone can host a Minecraft server with mods. You can do it from your computer, use a paid host, or use a free host like Aternos. The most important part is making sure all mods match the server version and are installed correctly.

How to Make Minecraft Server 1.21.5?

The process is almost the same as explained above. If 1.21.5 is a sub-version (like 1.21.1 or 1.21.5), download the correct version of Forge or Fabric for that sub-version, and install your mods accordingly. Always double-check that the server files and mods are built for that exact version.

Running a Minecraft server with only 1 GB of RAM is technically possible, but it is not optimal for most users. While it may suffice for hosting a small, vanilla server with just a few players, it will struggle when hosting larger worlds or using newer Minecraft versions. Servers with minimal RAM can experience lag, crashes, and long load times, especially if you add plugins or mods. For better performance, it’s recommended to have at least 2–4 GB of RAM to ensure smooth gameplay, especially with multiple players.

What Version of Java Does Minecraft 1.20.1 Use?

This version provides enhanced performance and security improvements, which is essential for optimal gameplay.

Does Aternos Support Mods?

Yes, Aternos does support mods. Aternos is a popular, free Minecraft server hosting service, and it allows players to install a variety of mods through its easy-to-use interface.

What Does Getsockopt Mean?

In the context of programming and server hosting, getsockopt is a system call used to retrieve the value of a socket option. It’s typically used to get information about a network socket, such as whether it is in blocking mode, the maximum size of the send/receive buffer, or whether there is a timeout for the connection.

Do I Need DDoS Protection on a Minecraft Server?

DDoS (Distributed Denial of Service) attacks can pose a significant threat to any online service, and Minecraft servers are no exception. These attacks are designed to overwhelm a server with massive amounts of traffic, rendering it inaccessible to legitimate players. If you’re hosting a Minecraft server, especially if it’s public or has a large player base, it’s wise to consider DDoS protection.

Minecraft servers can be particularly vulnerable to these attacks because they often rely on specific ports to allow players to connect. A DDoS attack targeting these ports can bring your server to a halt, disrupting the gaming experience for everyone involved. For servers with a significant player base, or if you’re operating a popular server, DDoS protection can help ensure the stability of your service and prevent downtime, ensuring that players can connect without interruptions.

There are several services and hosting providers that offer DDoS protection as part of their server hosting packages. Investing in a reliable protection service can save you from the headaches of dealing with downtime and player frustration. In short, while not mandatory for every server, DDoS protection is highly recommended for those who want to keep their server running smoothly.

Is Minekeep 24/7?

Minekeep is a Minecraft server hosting service that offers the ability to host Minecraft servers with high availability. When asking if Minekeep is 24/7, the answer is generally yes. Minekeep guarantees uptime for Minecraft servers, meaning that servers hosted with their service are designed to be available round the clock. However, as with any service, issues such as server maintenance, technical glitches, or hardware failure can occasionally cause temporary interruptions. Still, Minekeep’s infrastructure is built with uptime in mind, and most users should experience minimal disruptions.

For players and server administrators, the 24/7 availability of a hosting service like Minekeep is essential for uninterrupted gameplay. Whether you’re hosting a private server for friends or running a large-scale public server, the reliability of the hosting service plays a major role in keeping the server available at all times.

Are 1.20 and 1.20.1 the Same?

No, Minecraft 1.20 and 1.20.1 are not the same. While they share the same primary version number, the update labeled 1.20.1 is a patch update for Minecraft 1.20. The “1.20” version introduced major content and features to the game, including new mobs, blocks, and gameplay mechanics. However, patch updates like 1.20.1 typically focus on fixing bugs, improving performance, and addressing minor issues that players have encountered in the initial release.

Players can expect that 1.20.1 will contain bug fixes, optimizations, and stability improvements based on feedback from the community after the release of Minecraft 1.20. These patch versions are important because they ensure that players’ experiences are as smooth as possible, with fewer glitches or gameplay disruptions.

When Was 1.20.2 Released?

Minecraft 1.20.2 was released on August 9, 2023. This version came out after 1.20 and 1.20.1, offering additional bug fixes, optimizations, and improvements based on user feedback.

In the case of 1.20.2, players saw continued efforts to enhance performance and fix any issues that arose following the broader 1.20 update.

What Does 1.20 Add?

How to Get Mods on Minecraft 1.21.4?

To install mods on Minecraft 1.21.4 (assuming this refers to a future release), you’ll generally need to use a mod loader, with Forge and Fabric being the two most popular options. Here are the general steps to install mods:

Install Minecraft Forge or Fabric: Download and install the mod loader compatible with your Minecraft version.
Download the Mods: Visit trusted sources like CurseForge or Modrinth to download mods designed for the 1.21.4 version of Minecraft.
Place Mods in the Mods Folder: Once you have the mods, move them into the “Mods” folder located in your Minecraft directory.
Launch Minecraft: Open the Minecraft Launcher, select the Forge or Fabric profile, and start the game.

It’s always important to ensure that the mods you download are compatible with the Minecraft version you’re running to avoid crashes or issues.

Is Aternos Laggy with Mods?

Aternos is a popular free Minecraft server hosting provider that allows players to host their own Minecraft servers. While Aternos provides an easy way to host servers, performance can sometimes be an issue, especially when running mods. Mods often increase the resource demand on a server, which may lead to lag or slower performance, particularly with more complex or resource-heavy mods.

If you experience lag on an Aternos server with mods, it could be due to the limited resources available with the free hosting package. Upgrading to a paid server hosting solution with more dedicated resources might help mitigate the lag, or you could try optimizing your mod selection to include fewer performance-heavy mods.

Is CurseForge Safe?

Yes, CurseForge is generally considered a safe platform for downloading mods for Minecraft. CurseForge is a reputable site with a long history of providing mods, and it has a dedicated team that works to ensure that the files hosted on the site are free of malware and other harmful content. However, as with any online platform, it’s always important to double-check that you are downloading mods from trusted creators and avoid external sites that might host unverified files.

Is Minecraft 1.21.5 Out?

As of now, Minecraft 1.21.5 has not been released. New versions of Minecraft are regularly released, and each new update typically includes bug fixes, new features, or other improvements. The latest version will always be made available through the official Minecraft launcher, so it’s recommended to keep an eye on official channels for news on the latest releases.

Is Minecraft an 18?

Minecraft is rated E for Everyone, meaning it is suitable for all ages. However, the content within Minecraft can vary depending on the player’s actions. While the game itself is family-friendly, certain servers or mods may introduce more mature themes. The game’s sandbox nature allows for a wide range of player-created content, which may not always be suitable for younger audiences. It’s important for parents and guardians to monitor online interactions, especially in multiplayer environments.

Final Thoughts

Hosting a Minecraft 1.21 server with mods is easier than it sounds. You don’t need to be a coding expert. With just a little patience, you can build your dream world with dragons, magic, machines, or anything else the modding community creates.
