Best Minecraft Modpacks for a Server in 2026 (Top 10 With RAM Needs)

A good modpack can turn Minecraft into a factory game, an RPG, a roguelike or a Pokemon adventure, and all of them are better on a shared server where the world keeps going between sessions. These are the ten packs we think are most worth running on a server in 2026, each with the version, loader and memory it needs.

Before you pick

• Everyone must match the server. Modpacks need the same pack version on every client and on the server. Launchers like CurseForge, Modrinth and the FTB App install the exact version for players.
• Use the server files. Most packs publish a separate server pack. On CurseForge it is under Additional Files on the pack's Files tab.
• Java version matters. Packs on Minecraft 1.21.1 need Java 21, packs on 1.18.2 to 1.20.1 run on Java 17, and 1.12.2 packs need Java 8.
• Most packs lag behind vanilla. Minecraft itself is now on year based versions like 26.2, but most big packs still target 1.21.1 or older because that is where their mods are stable. That is normal.

For how memory is used and when to add more, see how much RAM a game server needs.

Quick comparison

The ranges assume a small group. Add memory for more players, big bases and heavy automation.

1. All the Mods 10

The kitchen sink pack. ATM10 bundles hundreds of tech, magic and exploration mods with a quest book that leads to crafting the ATM Star, an endgame goal that pulls every mod together. On a server it works beautifully because people naturally split up: one player builds a factory, another goes deep into magic, and it all feeds the same goal. It is also one of the heaviest packs, so give it room.

RAM: 8 GB for a few friends, 12 GB for a bigger group.

2. FTB StoneBlock 4

You start underground in a world made of stone and mine your way into a full tech and magic progression. StoneBlock is a long running series from Feed The Beast and the fourth entry is the most polished yet. Note that it needs command blocks turned on (enable-command-block=true in server.properties) or parts of progression break.

RAM: 6 GB minimum, 8 GB for a smooth group server.

3. Craftoria

A 1.21.1 pack with 500 plus mods and a huge quest book of more than 2,000 quests, blending tech like Mekanism and Applied Energistics 2 with magic like Ars Nouveau, plus seasons and world tiers that unlock tougher bosses. It is a good alternative for groups who have already played through ATM packs and want something fresh on a modern version.

RAM: 8 GB, or 12 GB for larger groups and big factories.

4. Cobblemon Official Modpack

Cobblemon adds Pokemon style creatures you can catch, train and battle, and the official pack wraps it with structures and quality of life mods so it works out of the box. It is the most approachable pack on this list for younger players and families, and it is still updated regularly.

RAM: 6 GB for a family or small group, 8 GB for more.

5. Prominence II: Hasturian Era

An RPG pack on Fabric 1.20.1 with story campaigns, voiced NPCs, dungeons, bosses and a talent tree. Friends can build very different characters and still tackle the same bosses together, which makes it one of the best adventure packs for a server.

RAM: 6 to 8 GB.

6. Better MC (BMC4)

Better MC keeps the feel of vanilla survival but makes everything bigger and prettier: new biomes, structures, mobs and dungeons without a heavy tech tree. It is the easiest pack to hand to friends who only know vanilla. Versions exist for both Fabric and Forge.

RAM: 6 GB, or 8 GB for more players.

7. Create: Astral

A tightly designed Create pack where you build contraptions, automate production and eventually launch into space to visit other planets. Its questline gives a group clear shared goals, and big spinning machines are more fun when your friends can see them.

RAM: 6 to 8 GB. Huge contraptions are more CPU bound than memory bound.

8. Vault Hunters 3rd Edition

Vault Hunters mixes normal modded survival with a roguelike loop: you enter procedurally generated vaults, grab loot and get out before the timer runs out. It is built for groups and has a big multiplayer community. Vaults generate on the fly, so it wants more memory than the mod count suggests.

RAM: 8 GB minimum, 12 GB for a busy server.

9. GregTech: New Horizons

The legendary hardcore pack. GTNH has a progression measured in months or years, with every recipe rebalanced around GregTech. It is still actively developed on 1.7.10 and now runs on modern Java. Perfect for a small dedicated group who want a long term project.

RAM: 8 GB, more for late game bases.

10. RLCraft

RLCraft is brutally hard survival on 1.12.2, with thirst, temperature, dragons and very little mercy. It has been around for years and remains one of the most played packs, mostly because dying together is funny. It is lighter than most packs here.

RAM: 4 to 6 GB.

Running a modpack on a server

1. Download the server pack for the exact version your players will use.
2. Start it once so it generates its files, then accept the EULA in eula.txt.
3. Set memory to match the table above. On a home server that means the -Xmx value in the pack's start script or user_jvm_args.txt.
4. Pre-generate the world around spawn with a tool like Chunky if the pack includes it, which cuts early lag.
5. Take a backup before updating the pack. Pack updates can remove mods and break worlds.

Which pack for your group

• Casual friends who like vanilla: Better MC or Cobblemon.
• Builders and engineers: Create: Astral or GregTech: New Horizons.
• A bit of everything: All the Mods 10 or Craftoria.
• RPG and bosses: Prominence II.
• Hardcore challenge: RLCraft.
• Something different: StoneBlock 4 or Vault Hunters.

With Minecraft server hosting you choose Forge, NeoForge, Fabric or a CurseForge or Modrinth modpack from the panel, and the 8 GB plan covers most of these packs for a small group.
