The Complete Guide to Minecraft Modpacks in 2026

Modpacks have transformed Minecraft from a simple sandbox into hundreds of different games. Whether you want factory automation, brutal survival challenges, or RPG-style progression, there’s a modpack for it. But the sheer number of options — and the technical setup involved — can be overwhelming.

This guide covers everything you need to know about playing and hosting modpacks in 2026.

What Exactly Is a Modpack?

A modpack is a curated collection of mods bundled together so they work as a cohesive experience. Instead of downloading 150 individual mods, troubleshooting conflicts between them, and configuring each one, someone has already done that work for you.

Modpacks typically include:

• Core mods that define the experience (tech, magic, exploration, etc.)
• Utility mods for quality of life (JEI/REI for recipes, minimap mods, inventory sorting)
• Performance mods (Sodium, Starlight, FerriteCore) to keep things playable
• Config files that tune mod settings for balance
• Custom recipes or quest lines that tie everything together

Most modpacks are distributed through CurseForge, Modrinth, or the FTB App. The mod loader is either Forge, NeoForge, or Fabric — and this distinction matters because mods built for one loader won’t work with another.

Top Modpacks in 2026

All The Mods 10 (ATM10)

The “everything but the kitchen sink” pack. ATM10 includes 300+ mods spanning tech, magic, exploration, and quality of life. It’s the spiritual successor to ATM9, updated for the latest Minecraft version.

• Style: Kitchen sink (a bit of everything)
• Difficulty: Medium — no imposed progression, play how you want
• Server RAM: 8-12GB recommended for small groups, 12-16GB for larger servers
• Best for: Groups who want maximum variety and freedom
• Note: Heavy on resources. Make sure both client and server have adequate RAM.

Better MC

A polished vanilla-plus experience. Better MC enhances every aspect of vanilla Minecraft — better terrain generation, more structures, new biomes, quality-of-life improvements — without fundamentally changing the game.

• Style: Vanilla-plus enhancement
• Difficulty: Easy to medium
• Server RAM: 4-6GB for small groups, 6-8GB for larger servers
• Best for: Players who love vanilla Minecraft but want more content
• Note: Excellent entry point for players new to modpacks.

Create

Built around the Create mod’s mechanical systems. Design factories, conveyor belts, water wheels, trains, and elaborate contraptions. It’s Minecraft meets engineering simulation.

• Style: Tech/engineering focused
• Difficulty: Medium (learning curve on the Create mod itself)
• Server RAM: 4-6GB for small groups, 6-10GB for larger servers
• Best for: Players who love redstone and automation
• Note: Create’s animations can be client-intensive. Players need decent GPUs.

RLCraft

The “hardest modpack ever made” — and it lives up to the reputation. RLCraft adds temperature, thirst, realistic torches that burn out, terrifying mobs, and a leveling system. You will die. A lot.

• Style: Hardcore survival RPG
• Difficulty: Brutal
• Server RAM: 6-8GB for small groups, 8-12GB for larger
• Best for: Players who want a punishing survival challenge
• Note: Not recommended for casual players or young kids. Genuinely difficult.

Vault Hunters

An RPG-style pack where players delve into procedurally generated vaults for loot, abilities, and progression. Each vault is a unique dungeon with timed challenges.

• Style: RPG / dungeon crawling
• Difficulty: Medium to hard
• Server RAM: 6-8GB for small groups, 8-12GB for larger
• Best for: Players who enjoy loot-driven progression and dungeon crawling
• Note: Vaults are instanced per player, so server load scales with active vault runners.

Cobblemon

Pokemon in Minecraft, built on Fabric. Cobblemon replaces Pixelmon with a from-scratch implementation that feels more integrated with Minecraft’s world. Catch, battle, and breed Pokemon in a multiplayer Minecraft world.

• Style: Pokemon adventure
• Difficulty: Easy
• Server RAM: 4-6GB for small groups
• Best for: Pokemon fans who want a multiplayer experience
• Note: Fabric-based, so it’s generally lighter weight than Forge packs.

How to Install a Modpack (Client Side)

Using CurseForge App

1. Download the CurseForge app from curseforge.com
2. Select Minecraft as your game
3. Browse modpacks or search by name
4. Click “Install” — the app handles downloading all mods and configuring the launcher
5. Click “Play” when installation completes

Using Modrinth App (Theseus)

1. Download the Modrinth app from modrinth.com
2. Search for your modpack
3. Click “Install”
4. The app creates a separate game instance with all mods configured

Using the FTB App

1. Download from feed-the-beast.com
2. Browse the FTB pack library
3. Click install and play

Manual Installation

For packs not on major platforms, or if you prefer manual control:

1. Install the correct mod loader (Forge, NeoForge, or Fabric) for the Minecraft version the pack targets
2. Download the modpack zip file
3. Extract into a new instance folder
4. Ensure the mods/, config/, and other pack folders are in the correct location
5. Allocate sufficient RAM in your launcher settings (see below)
6. Launch and verify

Setting Up a Modpack Server

Running a modpack on a multiplayer server requires the server-side component of the pack. Here’s the general process:

Step 1: Get the Server Files

Most modpacks provide a server download separate from the client download. This contains:

• The server jar (Forge/NeoForge/Fabric server)
• Server-side mods (client-only mods like shaders and minimaps are excluded)
• Configuration files
• A startup script

Step 2: Upload to Your Server

If you’re using a hosting provider like Witchly, this typically means:

1. Select the correct game and mod loader version when creating your server
2. Upload the server files via SFTP or the file manager
3. Ensure the startup command points to the correct server jar

Many hosts, including Witchly, offer one-click modpack installation that handles all of this automatically. Check if your specific modpack is supported before doing manual setup.

Step 3: Allocate Enough RAM

This is where people most commonly go wrong. Your server needs enough RAM for:

• The Java Virtual Machine overhead (~500MB-1GB)
• The mods themselves (varies wildly — 200 mods might need 2-4GB just for mod data)
• Loaded chunks and entities
• Player data

Refer to the modpack’s documentation or community forums for recommended server RAM. The tables earlier in this article give rough guidelines.

Step 4: Configure Server Properties

Key settings in server.properties:

• max-players: Set to your expected maximum
• view-distance: Lower this for better performance (8-10 for modded, down from the default 10-12)
• simulation-distance: Controls how far from players entities are simulated (6-8 for modded)
• max-tick-time: Some heavy modpacks need this increased to prevent watchdog crashes. Set to 60000 or -1 if you get “server overloaded” crashes during world generation

Step 5: Test Before Inviting Players

Join the server yourself first. Explore, craft some items, test mod interactions. Many mod conflicts only appear during gameplay, not during startup.

Client-Side vs Server-Side: What Goes Where?

This distinction confuses many new modpack server admins.

Client-Only Mods

These run only on the player’s computer and don’t belong on the server:

• Shader mods (Iris, OptiFine)
• Minimap mods (Xaero’s, JourneyMap) — some have server-side components, most don’t
• HUD mods (AppleSkin, Jade)
• Performance mods that only affect rendering (Sodium, Embeddium)

Installing client-only mods on the server usually causes crashes or errors on startup.

Server-Only Mods

These run only on the server:

• Permission mods (LuckPerms)
• Server utility mods (Chunky for pre-generation)
• Anti-cheat mods

Shared Mods

Most content mods (new blocks, items, mobs, machines) need to be on both the client and server. If a mod is in the modpack’s server download, it should also be in your client installation, and vice versa. Version mismatches between client and server mods will prevent players from connecting.

Performance Tips for Modded Servers

Allocate RAM Correctly

In your server’s startup script or hosting panel, set both minimum and maximum heap size:

-Xms4G -Xmx8G

Don’t set -Xms and -Xmx to the same value for modded servers. Allowing the JVM some flexibility helps with garbage collection.

Use Appropriate Java Flags

Modern Java (17+) benefits from optimized garbage collection flags. GraalVM or Aikar’s flags are widely recommended for Minecraft:

-XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200
-XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC
-XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40
-XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20
-XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15
-XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5
-XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem
-XX:MaxTenuringThreshold=1

Pre-Generate Your World

World generation is the single most CPU-intensive task for modded Minecraft. Modpacks with custom worldgen (Terralith, BOP, etc.) are especially demanding.

Use Chunky to pre-generate a reasonable area (5000-10000 block radius) before players join. This shifts the CPU cost to a one-time operation instead of ongoing spikes during exploration.

Set a World Border

Without a world border, players can explore infinitely, generating an ever-growing world file. Set a border appropriate for your player count and storage limits. For most modded servers, a 10000-20000 block radius provides more than enough space.

Monitor and Adjust

Use Spark (available for both Forge and Fabric) to profile your server. It shows exactly which mods, entities, and chunks are consuming the most resources, letting you make informed decisions about optimization.

Getting Started

The best way to pick a modpack is to try a few on singleplayer first. Most packs play very differently from each other, and personal preference matters more than popularity rankings.

Once you’ve found a pack your group enjoys, setting up a dedicated server lets everyone play together without the host needing to be online. Hosts like Witchly offer one-click modpack installation and dedicated resources so you can focus on playing instead of troubleshooting server configurations.
