Forge, NeoForge, Fabric or Quilt: Which Modloader to Choose?
Which modloader you need is decided by your modpack rather than by you: every pack is built for exactly one loader. NeoForge is the modernised fork of Forge, leads on Minecraft 1.20.2 and newer and carries the big content packs such as All the Mods 10 (Minecraft 1.21.1, more than 18 million downloads on CurseForge). Forge has the largest legacy and keeps classics like RLCraft (Forge 1.12.2, 27-plus million downloads) alive, Fabric is the lightweight loader that follows new versions fastest and is the home of Sodium and Lithium, and Quilt is a fork of Fabric with a distinctly smaller ecosystem.
What does a modloader actually do?
Vanilla Minecraft has no concept of mods. A modloader sits between the game and your mods: it patches the game code, gives mods a shared API for registering new blocks, items, mobs and dimensions, and makes sure hundreds of mods do not trample over each other. Without a loader, a mod jar is just a file Minecraft ignores.
That is also the biggest difference from plugins. Plugins for Paper or Purpur run purely server-side on otherwise vanilla mechanics: your players install nothing, whether it is EssentialsX for /home and /tpa or LuckPerms for ranks. Our overview of the best Minecraft plugins runs through them. Mods work the other way round: they have to be present on server and client in exactly the same version. Choosing a loader therefore also decides what your players have to install.
Forge, NeoForge, Fabric and Quilt side by side
All four do the same job, with a different history and a different audience. Here is how it stands in 2026.
| Loader | Origin | Strength | Typical packs | Version speed |
|---|---|---|---|---|
| Forge | The oldest, the standard for modded Minecraft for years | The largest legacy, above all on older versions | RLCraft (Forge 1.12.2, 27-plus million downloads) | Slow; heavier and later to new versions |
| NeoForge | Fork of Forge that modernises the same codebase | Leads on 1.20.2 and newer, carries the big content packs | All the Mods 10 (Minecraft 1.21.1, more than 18 million downloads) | Brisk; the de facto new standard |
| Fabric | Built separately from Forge as a lightweight loader | Light and fast, home of Sodium and Lithium | Fabulously Optimized (12-plus million on Modrinth), Create: Astral (Fabric 1.18.2) | Fastest to follow new versions |
| Quilt | Fork of Fabric | Its own design choices, close to Fabric | Few large packs; rarely a requirement | Follows Fabric, with a smaller ecosystem |
Do not read those download counts as a verdict on quality: mostly they tell you how long a pack has existed. RLCraft had years on 1.12.2, while All the Mods 10 on 1.21.1 is a good deal younger.
Do you choose the loader, or does your modpack?
In most cases you choose nothing at all. If you run an existing modpack, the authors already picked the loader and the required build is listed on the pack page. All the Mods 10 is a NeoForge pack and will not run on Fabric; RLCraft is a Forge pack on 1.12.2 and does not simply move across. Go against that and you are effectively building your own pack.
You do choose when you assemble your own mod list: then you look at where the mods you genuinely want live, and that majority points at the loader. How packs fit together is covered in our guide to what a modpack is and how you install one.
Keep an eye on the Minecraft version too. Java has used year-based version numbers since 2026: the 1.21.x series was followed by 26.1 "Tiny Takeover" (March 2026) and 26.2 "Chaos Cubed" (June 2026), and 26.3 with the dappled forest biome is still in snapshots. The mod ecosystem always trails behind: 1.21 "Tricky Trials" with the Trial Chambers, Vaults and the Mace is still the most played version on Dutch servers, and it is where most serious packs live.
Do Forge mods run on Fabric as well?
No. The loaders hook into the game code in different places and hand mods a different API. A Fabric mod in the mods folder of a NeoForge server is ignored at best and crashes the server during loading at worst. The same applies in reverse, and between Forge and NeoForge too: they share a past but have grown apart. So always take the build your pack names, not the newest one.
Compatibility layers exist that try to run mods from one loader on another. They sometimes work surprisingly well, but they remain an extra layer that breaks with every update to the mod, the loader or Minecraft. On a server with several players I would not build on that; better to check whether your mod has a native version for your loader.
Quilt is the edge case: as a fork of Fabric it aims to load the same kind of mods, but treat it as a separate loader unless a pack explicitly asks for it.
When do you pick which loader?
Forge
Pick Forge when the mod or pack you want lives there, which is often on older versions. Around 1.12.2 sits an enormous body of work that never moved across, with RLCraft as the best-known example. The downside: Forge is heavier, loads more slowly and arrives later on new versions. For something new it is rarely the logical choice in 2026.
NeoForge
Pick NeoForge for a large content pack on a modern version. This is where the kitchen-sink packs live: All the Mods 10 with 400 to 500-plus mods needs Java 21 and at least 10 GB of RAM. The optimisation mods are in good shape: FerriteCore saves 30 to 40 percent memory, while Canary and ModernFix cut loading time and tick pressure.
Fabric
Pick Fabric if you want to travel light or get onto a new Minecraft version quickly. Sodium and Lithium belong here, and Fabulously Optimized bundles exactly that without touching the game world. The downside: the very largest content packs turn up here less often, though there are exceptions such as Create: Astral on Fabric 1.18.2.
Quilt
Pick Quilt only when a pack or mod explicitly asks for it. The ecosystem is small and for most people it adds nothing that Fabric does not already do.
What does your server notice about the loader choice?
What your server feels is mainly the number of mods, not the loader itself. Three things do tie directly to your loader choice.
- The Java version. It follows the Minecraft version, and your loader decides which version you are on. All the Mods 10 on 1.21.1 requires Java 21 and will not start on Java 17.
- Memory. Big Forge and NeoForge packs are memory hogs because every mod registers its own blocks, items and recipes. For All the Mods 10, 10 GB is the minimum, 12 GB is comfortable for a small group and 14 to 16 GB is sensible with five players or more. A Cobblemon pack, by contrast, often runs happily on 4 to 8 GB.
- Storage. Reading hundreds of mods is disk work: on a mechanical hard disk a large pack takes 10 minutes or more to start, on an SSD 2 to 3 minutes.
That translates straight into your hosting: with Minecraft hosting at MC-Node the budget line costs EUR 1.10 per GB of RAM per month, which puts 8 GB at EUR 8.80; larger packages are cheaper per GB, so 15 GB comes to EUR 15.00. Before you buy more, check what is still to be gained from your current server; optimising your Minecraft server is the cheaper first step.
Decision tree: which modloader suits you?
Work down the list and stop at the first one that fits.
- Are you running an existing modpack? Then the choice is already made. Take the loader and the exact build from the pack page. Done.
- Do you only want better performance, not new content? Then you need no modloader on the server side at all: Paper is the default choice, and on the client side a Fabric pack like Fabulously Optimized does the rest.
- Do you want a big content pack with machines, dimensions and quest lines on a modern version? NeoForge, and budget for plenty of memory.
- Is the mod you absolutely want only available on 1.12.2 or another old version? Forge, with the Java version that pack prescribes.
- Do you want to be on a new Minecraft version quickly, or run a light mod list? Fabric.
- Does a pack or mod explicitly ask for Quilt? Then Quilt, and otherwise not.
If you are torn between mods and plugins, weigh up the admin side as well: plugins are simpler to update, while mods deliver genuinely new content but tie everyone to the same version.
Frequently asked questions
Can I run Forge mods on NeoForge? Not just like that. NeoForge began as a fork of Forge, but the projects have grown apart and on 1.20.2 and newer NeoForge is the leading loader. Always take the mod and loader build your pack names, not the newest version.
Which modloader is the fastest? Fabric is the lightest and the home of Sodium and Lithium, but in practice the number of mods shapes your performance more than the loader does. On NeoForge, FerriteCore delivers 30 to 40 percent lower memory use, and Canary and ModernFix cut loading time and tick pressure.
Which loader does All the Mods 10 use? NeoForge, on Minecraft 1.21.1. The pack has more than 18 million downloads on CurseForge, contains 400 to 500-plus mods and requires Java 21; on Java 17 it will not start. Budget for at least 10 GB of RAM for the server.
Should I use Quilt if I run Fabric mods? No. Quilt is a fork of Fabric with a smaller ecosystem, and for most servers it adds nothing over Fabric itself. Use it only when a pack or mod explicitly asks for it.
Do mods from a modloader work with plugins such as EssentialsX? Not in the same installation without hybrid server software, and that tends to lag behind new Minecraft versions. Plugins run on Bukkit variants such as Paper and Purpur, mods on Forge, NeoForge, Fabric or Quilt. For a stable modpack server, stick to the loader your pack prescribes.
