Minecraft Modded Server Hosting: Forge, Fabric and RAM

By Alex Rivera · Published July 15, 2026 · Updated July 15, 2026

Minecraft modded server hosting is a managed server service that runs a Forge or Fabric server for you, so your whole friend group can play the same mods together without anyone leaving their own computer on overnight.

Quick answer: To run a modded server you need three things: a Forge or Fabric server, enough RAM for your mod list, and every player running the same mods locally. The rule of thumb is 2 GB for a handful of light Fabric performance mods, 4 GB for 10 to 30 mods, and 8 GB for big modpacks. Expect to pay roughly $15 to $45 per month for hosting, depending on how heavy your pack is.

Mods vs plugins: what's the difference?

People mix these up constantly, and it matters, because they need different server types and different amounts of work.

Mods (Forge or Fabric) change the game itself: new blocks, new dimensions, new machines, Create contraptions, that kind of thing. Plugins (Paper or Purpur) add server-side features like land claims, economies, and minigames without touching the game files on anyone's computer.

If all you want is claims, teleports, and a shop for a vanilla-feeling server, use plugins. They are less work for everyone. If you want Create, Ars Nouveau, or a full modpack experience, you need mods, and this guide is for you.

One more honest note: mods are a Java edition thing. NovaCraftHost hosts both Java and Bedrock, but Forge and Fabric servers are Java only, so everyone in your group needs Java edition to play modded. More on that in our guide to Java server hosting.

Forge or Fabric: which should you pick?

Pick based on the mods you want, not on loyalty. Most mods are built for one loader or the other.

• Forge is the older, heavier loader. Most big classic modpacks and large tech and magic mods target Forge. If your group wants a famous kitchen-sink pack, it is probably Forge.
• Fabric is lighter and faster to update to new Minecraft versions. Performance mods like Lithium and quality-of-life mods tend to live here. If your group wants near-vanilla plus 10 to 20 handpicked mods, Fabric is usually the better call.

The practical method: build your wishlist of mods first, check which loader they support, then create the server to match. On NovaCraftHost you pick Forge or Fabric and the Minecraft version when you create the server, and you can change both later in settings. Just know that switching loaders mid-world usually means mod content disappears, so decide before you get attached to your base.

How much RAM do mods really need?

RAM is the single biggest factor in whether a modded server feels good. Vanilla logic like "2 GB is plenty" stops applying fast once mods load thousands of extra blocks, entities, and recipes into memory.

Player count matters less than mod count. Five friends on a 150-mod pack will hurt a 4 GB server far more than fifteen friends on near-vanilla. When in doubt, start one tier lower and upgrade if you see lag; that beats overpaying from day one.

How do you install mods on a hosted server?

Here is the honest version: NovaCraftHost does not have a one-click modpack installer. Installing mods means uploading the mod files yourself through the web file manager. It is not hard, but it is a real step, so here is the exact process.

1. Create a Forge or Fabric server. Pick the loader and the Minecraft version your mods need. Mods are version-specific, so a 1.20.1 mod will not load on a 1.21 server.
2. Download the server-side mod jars. Get them from Modrinth or CurseForge, matching your exact Minecraft version and loader.
3. Upload them to the mods folder. Open the web file manager, go to the mods folder, and upload the jars. No FTP client needed, it all happens in the browser.
4. Restart the server. Watch the console while it boots. If a mod is missing a dependency or built for the wrong version, the log tells you which one, and you fix it by adding or removing that jar.
5. Everyone installs the same mods locally. Each player adds the same mods (same versions) to their own Minecraft install, usually via the CurseForge app, Modrinth app, or Prism Launcher. Client-only mods like minimaps or shaders do not need to go on the server.

For a big modpack, the flow is the same but bigger: upload the pack's server files to your server, and have every player install the pack itself in their launcher. Budget 20 to 30 minutes the first time. If mismatched versions get someone kicked on join, the error message names the mod that does not match.

Why is my modded server slow and how do you fix it?

Modded lag almost always comes from one of four places. Work through them in order.

• Not enough RAM. If the server stutters, hangs on world generation, or crashes with out-of-memory errors, you are underprovisioned. Move up a tier. This fixes the majority of cases.
• One misbehaving mod. Check the console and metrics after adding new mods. If tick times spiked when a specific mod arrived, remove it and confirm.
• Chunk-loading machines. Giant Create contraptions, quarries, and mob farms that run in loaded chunks eat server time even when nobody is nearby. Spread them out or scale them down.
• Slow startup after sleep. NovaCraftHost servers auto-sleep when empty to save resources, and modded servers take longer to wake than vanilla, usually a minute or two. That first slow join is normal, not lag. Once it is up, it stays up while people are playing.

On Fabric, adding Lithium and FerriteCore is nearly free performance. On Forge, ModernFix helps startup and memory. These are server-side, so uploading them to the mods folder benefits everyone without players changing anything.

What should you look for in a modded server host?

Any host can technically run Forge. The things that matter for a friend group are the boring ones: automatic daily backups with restore (mods corrupt worlds more often than vanilla does), a web file manager that makes uploading mod jars painless, a live console for reading crash logs, and a friendly server address your group can actually remember. Every NovaCraftHost plan includes all of those. For a wider comparison of what separates good hosts from cheap ones, read our guide to the best Minecraft server hosting.

Also check the exit terms. NovaCraftHost bills monthly through PayPal, you can cancel anytime, and your world is kept for 14 days after cancellation, so a summer-only server is a real option.

How do you get started?

Pick a plan based on your mod count using the table above, create a Forge or Fabric server (it is live in minutes), upload your mods through the file manager, and share the server address with your group. Have everyone install the same mods locally, then join. Compare NovaCraftHost plans and start with the tier that matches your pack; you can move up later if the pack grows.

Bottom line: A modded server for your friend group needs a Forge or Fabric server, RAM matched to your mod count (2 GB light, 4 GB for 10 to 30 mods, 8 GB for big packs), and the same mods on the server and every player's computer. There is no magic one-click button for modpacks, but with a web file manager and a console the whole setup is a one-evening job, and daily backups mean a bad mod never costs you the world.

Frequently asked questions

Do my friends need to install mods to join my modded server?

Yes. Every player needs the same mods, at the same versions, installed in their own Minecraft launcher. Client-only mods like minimaps and shaders are the exception; those can differ per player. The easiest route is having everyone install the same modpack through the CurseForge app, Modrinth app, or Prism Launcher.

Can Bedrock players join a Forge or Fabric server?

No. Forge and Fabric mods only exist for Minecraft Java edition, so everyone in your group needs Java to play modded. NovaCraftHost hosts Bedrock servers too, but if mods are the goal, create a Java server and make sure your whole group plays Java.

How many mods can I run on a 4 GB server?

Roughly 10 to 30 mods runs well on 4 GB for a small friend group, depending on how heavy the mods are. A few large tech mods can cost more than twenty small quality-of-life mods. If tick times climb or the server crashes with memory errors, that is your cue to move to 8 GB.

Does NovaCraftHost have a one-click modpack installer?

Not for modpacks. You create a Forge or Fabric server, then upload the pack's server files or individual mod jars through the web file manager and restart. Plugins are different: on Paper and Purpur servers you can install plugins from Modrinth in one click, because plugins are server-side only.
