How to Play Modded Minecraft With Friends

Before choosing a method, understand the constraint that shapes all of them. Any mod that adds blocks, items, mobs or recipes must be installed on every participant's machine and on whatever is hosting the world, at identical versions.

A mismatch produces an immediate rejection when someone tries to connect, usually naming the offending mod, which is at least a clear failure rather than a silent one.

Client-side mods are the exception and they are exempt entirely. Shaders, minimaps, performance mods and interface tweaks live only on the player's own machine. The host neither knows nor cares whether you are running Sodium, so everyone can differ freely there.

The practical consequence: coordinating a mod list is the real work in modded multiplayer, and it is why using a published modpack rather than a hand-assembled list saves so much trouble.

Open a single-player world, press Escape, and choose Open to LAN. Anyone on the same network can then join from their multiplayer list without any configuration.

It is genuinely instant and costs nothing, and for people in the same house it is the obvious answer. It also inherits your mods automatically, since it is your game hosting.

The limitations are real. Everyone has to be on the same physical network, the world only exists while your game is open, and your machine is running both the client and the server, which on a large pack is demanding.

LAN is the right answer for a weekend with someone in the next room and the wrong answer for anything ongoing.

Essential is a mod that adds an invite system to Minecraft, letting you host a world for friends over the internet without touching your router. You install it, open a world, and invite people from a friends list.

It is free for the basic hosting, works with most modpacks, and requires no port forwarding, which removes the single most common obstacle to self-hosting.

The trade-offs are that everyone needs Essential installed, the world only exists while the host is playing, and the connection is relayed through their infrastructure so latency is a little higher than a direct connection.

For a group that wants something Realms-like and free, and does not need the world to persist when everyone logs off, this is the most convenient option available.

Running a dedicated server on your own computer gives you a persistent world with no ongoing cost. The world exists independently of anyone's game session, so people can play whenever the machine is on.

Setup involves downloading the server files for your loader, accepting the EULA, copying your mods into the server's own mods folder, and forwarding TCP port 25565 on your router.

That last step is where most attempts stall. Router interfaces vary enormously, some ISPs use carrier-grade NAT which makes port forwarding impossible, and getting it wrong exposes more than intended. Tunnelling services like Playit.gg sidestep the router entirely and are the pragmatic fallback.

The ongoing cost is that your machine has to stay on, and your upload bandwidth — usually a fraction of your download speed — determines everyone else's experience.

A rented server removes every operational problem at once. It is on permanently, it has its own bandwidth, it does not compete with your game for memory, and most hosts install popular modpacks with a single click.

Cost for a modded-capable plan is roughly five to fifteen pounds a month depending on memory, which is usually split between the group and works out to very little each.

The one-click modpack installation deserves emphasis. Setting up a three-hundred-mod pack by hand on a self-hosted server is an evening of copying files and matching versions; on a host that supports it, it is a dropdown and two minutes.

Billing is normally monthly with no contract, so trying one costs a month rather than a commitment.

Minecraft Realms is Mojang's own subscription hosting, and it is the first thing most people think of. For Java Edition it supports no mods whatsoever — not Forge, not Fabric, not a single .jar.

This catches people out constantly, because Realms is advertised inside the game and looks like the official answer to playing with friends. It is, for vanilla.

Bedrock Realms do support addons, which adds to the confusion when a Bedrock player tells a Java player it works fine.

If you have already bought Realms and want mods, the subscription is not wasted — it is simply the wrong product for this. Cancel or keep it for vanilla worlds and use one of the four methods above.

The decision comes down to two questions: does the world need to exist when the host is offline, and how many people are playing.

If everyone is in the same building and it is casual, LAN. If you want Realms-like convenience for free and do not need persistence, Essential. If you want persistence and enjoy the technical side, self-host. If you want persistence and would rather not think about it, rent.

Group size pushes toward renting faster than people expect. At two or three players a self-hosted server is comfortable; at six, your upload bandwidth and your machine's memory are both under real pressure.

However you host, everyone needs the same content mods, and there are three ways to achieve that with very different amounts of friction.

Use a published modpack and everyone installs the same thing from the same launcher. The lists match by construction and updates are coordinated. This is comfortably the best option and it is why packs dominate modded multiplayer.

Export your own pack from Prism Launcher or the Modrinth app and share the file. Each person imports it once. Nearly as good, with the small overhead of maintaining it yourself.

Zip your mods folder and send it round. This works for four people and stops working around eight, because every update means another round of files and someone always misses one.

The most common way an established modded group breaks is an uncoordinated update. One person's launcher auto-updates the pack, they can no longer connect, and nobody is quite sure what changed.

Turn off automatic pack updates on every client. This is a per-instance setting in most launchers and it prevents the whole category of problem.

Update deliberately, together, and update the server first. Announce it, take a backup, move the server, then have everyone update. Ten minutes of coordination beats an evening of confusion.

Keep a note of the pack version everyone is on. When someone rejoins after a month away, that note tells them exactly what to install.

A single-player world you break is your problem. A shared world represents everyone's time, and losing it is a considerably worse outcome.

Rented servers almost always include automated backups. Find the setting and confirm it is enabled rather than assuming — several hosts ship it switched off by default.

Self-hosted servers back up nothing. Copy the world folder on a schedule, and always before a mod-list change, which is when worlds actually break.

Keep at least one backup somewhere other than the machine running the server. A drive failure that takes the server also takes backups stored beside it.

For most groups: use a published modpack, rent a server with one-click installation of that pack, split the cost, and turn off automatic updates on every client.

That combination removes port forwarding, mod-list drift, uptime and backups from your life for roughly the price of a coffee each per month, and it is why it is what most established modded groups end up doing.

Start with LAN or Essential if you are just trying modded multiplayer for an evening. Move to a rented server when you find you want the world to still be there next week.
