Most mod download pages make you pick a file: Fabric or NeoForge, and on older versions Forge too. That pick decides which mods and modpacks you can run and how soon you can move to a new Minecraft version, because a mod built for one loader does not load on the other. Below is how the two compare on performance, mods, versions and Java, and where Forge still fits, checked on 31 October 2026 against the loaders' own version lists, Mojang's version files and the mods' own pages.
Quick answer: Install the loader your modpack or most important mod names, because Fabric and NeoForge mods do not load on each other. Pick Fabric for a light setup close to vanilla: the Sodium developers recommend it to new users, and it reaches new Minecraft versions first, with builds for the 26.4 snapshots that NeoForge does not have yet. Pick NeoForge for big content and tech mods: All the Mods 10 and 11, Create, Mekanism and Applied Energistics 2 run on it. Performance alone is no longer a reason to switch, since Sodium, Lithium, Iris and FerriteCore ship for both loaders on Minecraft 26.3. Forge is for packs on 1.20.1 and older. On any loader, every Minecraft 26.x version needs Java 25, and 1.20.5 to 1.21.11 need Java 21.
Fabric vs NeoForge at a Glance
| Fabric | NeoForge | |
|---|---|---|
| What it is | "A modular, lightweight mod loader", plus Fabric API, a separate mod with the hooks most Fabric mods use | A fork of Forge, started in July 2023; the API comes with the loader |
| Newest build | Loader 0.20.1 (19 October), the same loader for 1.21.1 and 26.3 | 26.3.0.100 (31 October), one build line per Minecraft version |
| Newest Minecraft | 26.3, plus the 26.4 snapshots | 26.3, stable builds since 11 October |
| Performance mods on 26.3 | Sodium, Lithium, Iris, FerriteCore, Moonrise, C2ME, Krypton | Sodium, Lithium, Iris, FerriteCore, Moonrise |
| Well-known packs | Fabulously Optimized, Cobblemon Official Modpack, COBBLEVERSE | All the Mods 10, All the Mods 11 (beta) |
| Tech mods | Create (through a separate port) and Applied Energistics 2, both only up to 1.20.1 | Create 6, Mekanism, Applied Energistics 2 |
| Server setup | One launcher jar, no installer | An installer, then a start script |
Fabric vs NeoForge Performance
Neither project publishes a speed test against the other, and we have not run one, so here is what the developers write. Sodium has shipped for both loaders since version 0.6.0, and its README says: "We generally recommend that new users prefer to use the Fabric mod loader, since it is more lightweight and stable (for the time being.)"
Beyond that, frame rate and tick time come down to the mods you add. What their own pages say they do, and their 26.3 builds on 31 October:
| Mod | What its developers say it does | Where it runs | 26.3 builds |
|---|---|---|---|
| Sodium | Rendering engine that "improves frame rates and reduces micro-stutter" | Client only | Fabric, NeoForge |
| Iris | Shader pack loader meant to work with OptiFine shader packs | Client only | Fabric, NeoForge |
| Lithium | Optimizes game logic and "doesn't change any game mechanics or visuals" | Client and server | Fabric, NeoForge |
| FerriteCore | "Memory usage optimizations" | Client and server | Fabric, NeoForge |
| Moonrise | Optimizes the server, with "measurably lower tick times" | Mainly the server | Fabric, NeoForge |
| ModernFix | Shorter launch and world load times, lower memory use | Client and server | None yet; current builds for 1.21.1 and 26.1.2 are NeoForge only |
| C2ME | Faster chunk generation, I/O and loading on several CPU cores | Server, optional on the client | Fabric only, alpha builds |
| Krypton | Optimizes the networking stack | Mainly the server | Fabric only |
For a server, Sodium and Iris do nothing: Modrinth marks both as unsupported on the server side, so they only help your players' clients. On the server, Lithium, FerriteCore and Moonrise run on both loaders, Fabric adds C2ME and Krypton, and NeoForge keeps ModernFix, whose last Fabric build for 1.21.1 is from November 2025. Moonrise's README lists C2ME as incompatible, because Moonrise replaces the chunk system that C2ME changes, so pick one of the two. C2ME's 26.3 builds are all alpha, and its README asks you to back up your worlds.
Older guides, this one included, sent NeoForge players to Embeddium and Oculus. Embeddium's last build is for 1.21.1 (January 2025) and Oculus stops at 1.20.1; Sodium and Iris now publish NeoForge builds themselves.
For numbers on your own server, use spark, a profiler with builds for Fabric, NeoForge and Forge. Run as an operator:
/spark tps
/spark health
/spark profiler start --timeout 60
/spark tps shows the tick rate and CPU usage, /spark health adds memory and disk use, and the profiler stops after one minute and links to the results in spark's online viewer. For a fair comparison, test a copy of the same world with mods that exist for both loaders.
Mods and Modpacks on Each Loader
On Modrinth on 31 October 2026, 47,552 mods carry the Fabric tag and 30,381 the NeoForge tag; for Minecraft 26.3 it is 9,008 against 5,137. Many mods carry both tags, and CurseForge, where the All the Mods packs are published, is not in these counts. What matters more is where your must-have mods are:
- NeoForge only, from 1.21.1 on: Create (6.0.10, for 1.21.1), Mekanism (10.7.19, for 1.21.1) and Applied Energistics 2, which has an alpha for 26.3 and Fabric builds only up to 1.20.1. Create's Fabric port, made by a separate team, also stops at 1.20.1.
- Fabric only: Fabric API itself, and C2ME and Krypton among the performance mods.
- Both, as separate files: Cobblemon (1.8.4 for 1.21.1, released 27 October), Sodium, Lithium, Iris, JEI, Jade, Distant Horizons, Simple Voice Chat, Geyser and Terralith.
Modpacks follow the same split. The most downloaded Fabric modpacks on Modrinth are Fabulously Optimized, a graphics and performance pack already on 26.3, and two Cobblemon packs on 1.21.1, the Cobblemon Official Modpack and COBBLEVERSE. On CurseForge, All the Mods 10 (version 8.4, 29 October) runs NeoForge on 1.21.1, and All the Mods 11 (0.13.0-beta, 27 October) runs NeoForge on 26.1.2. A NeoForge server with Create or Mekanism stays on 1.21.1 for now, since neither has a 26.x build on Modrinth yet.
Minecraft Versions and Java 25
Fabric keeps the loader separate from the game: loader 0.20.1, the only build Fabric marks stable, runs 1.21.1 as well as 26.3, paired with the Fabric API file for your version. NeoForge has one build line per Minecraft version. Since 26.1 its version numbers have four parts: the first three are the Minecraft version, the last is the NeoForge build, and a -beta suffix means breaking changes are still allowed, as NeoForged's 26.1 post explains.
| Minecraft | Java | Fabric API | NeoForge | Forge |
|---|---|---|---|---|
| 26.3 | 25 | 0.165.0+26.3 | 26.3.0.100 | 66.1.2 |
| 26.1.2 | 25 | 0.155.3+26.1.2 | 26.1.2.125 | 64.1.5 |
| 1.21.1 | 21 | 0.116.17+1.21.1 | 21.1.265 | 52.1.20 |
Newest builds on 31 October 2026; Java as set in Mojang's version files, whatever the loader.
Mojang released 26.3 on 15 September 2026. Fabric API's first build labelled 26.3 is dated 14 September on Modrinth. NeoForge's first 26.3 beta followed on the evening of 15 September and its first stable build, 26.3.0.76, on 11 October; Forge's first 26.3 build came on 19 September. Fabric API also has beta builds for the 26.4 snapshots, while NeoForge has none yet.
On a server or VPS you manage yourself, check Java first:
java -version
The first line has to show version 25 for 26.1 to 26.3, and 21 for 1.20.5 to 1.21.11.
Installing Each One on a Server
Fabric's server launcher is one jar that "will start the Fabric enabled Minecraft server", with "no need to use an installer", in Fabric's words. For 26.3, loader 0.20.1 and installer 1.1.2, Fabric's server page gives these two commands, the second with 2 GB of RAM:
curl -OJ https://meta.fabricmc.net/v2/versions/loader/26.3/0.20.1/1.1.2/server/jar
java -Xmx2G -jar fabric-server-mc.26.3-loader.0.20.1-launcher.1.1.2.jar nogui
NeoForge's installer builds the server folder. The RAM goes in the user_jvm_args.txt file it creates, and run.sh, or run.bat on Windows, starts the server:
curl -LO https://maven.neoforged.net/releases/net/neoforged/neoforge/26.3.0.100/neoforge-26.3.0.100-installer.jar
java -jar neoforge-26.3.0.100-installer.jar --installServer
./run.sh
Both stop on the first start after writing eula.txt. Set eula=true in it to accept the Minecraft EULA, and start again. On Fabric, also put the Fabric API jar for your Minecraft version in the mods folder; NeoForge has no separate API mod. Full steps: installing Fabric Loader, Fabric API and installing NeoForge.
Forge vs NeoForge vs Fabric: Where Forge Fits in 2026
NeoForge began on 12 July 2023, when almost all of the Forge team moved to the new NeoForged project, as its announcement explains. Forge is still updated: 66.1.2 for Minecraft 26.3 came out on 29 October 2026, with 66.1.0 marked as recommended. On 1.20.1 the two were still close: NeoForge's 1.20.1 build keeps Forge's mod id, so many 1.20.1 Forge mods load on it. With 1.20.2 NeoForge renamed its packages and its mod id, and since then mods are built for one or the other. On Modrinth, 35,516 mods carry the Forge tag, but only 2,607 of them list 26.3.
So in the three-way choice: Forge for packs on 1.20.1 or older, NeoForge for new Forge-style packs from 1.21.1 on, Fabric for light setups and new versions. Our Forge vs NeoForge comparison covers which Forge mods still work where.
All three load mods, not Bukkit or Paper plugins; for economy, permissions or chest shops you want Paper or Purpur, compared in Paper vs Purpur vs Spigot.
Can Fabric and NeoForge Mods Mix?
Not out of the box. A Fabric jar does not load on NeoForge or Forge, and the other way round. Many mods ship one file per loader, as Sodium, Lithium and Cobblemon do, so take the file that matches yours. Sinytra Connector, used with Forgified Fabric API, "allows running Fabric mods on NeoForge", and only in that direction. Every Connector build on Modrinth is marked beta, and none is out for 26.3 yet, so on a server your players depend on, stick to mods built for your loader.
Moving an existing world to the other loader means swapping most of its mods, so back it up first. Our guide to updating a modpack without losing your world covers the backup.
Fabric or NeoForge for Your Server
- Your modpack names a loader. Use that one; CurseForge and Modrinth show it next to the Minecraft version, such as NeoForge 1.21.1 for All the Mods 10.
- A vanilla-like SMP with performance mods. Fabric. Lithium, FerriteCore, Moonrise or C2ME, Krypton, Simple Voice Chat and Geyser for Bedrock players all have Fabric builds for 26.3.
- Cobblemon. Either loader runs the mod, but the official modpack and COBBLEVERSE are Fabric packs.
- Create, Mekanism, Applied Energistics 2 or a kitchen-sink pack. NeoForge, on 1.21.1 for Create and Mekanism.
- The newest Minecraft version in its first weeks. Fabric.
- An older 1.20.1 pack. Forge, or NeoForge's 1.20.1 build if the pack names it.
On our Minecraft plans you pick Fabric, NeoForge or Forge in the Pterodactyl panel and set the Java version yourself, and popular modpacks install from the panel's modpack installer. For RAM, our modpack hosting page lists what we suggest for each pack.
FAQ
Is Fabric better than NeoForge? Not across the board. Fabric is lighter and first on new Minecraft versions; NeoForge has Create, Mekanism and All the Mods 10. The mods you want decide it.
Is Fabric faster than NeoForge? Neither project publishes a benchmark against the other, and we have not measured one. The Sodium developers call Fabric "more lightweight and stable (for the time being.)" On 26.3 the main performance mods run on both loaders, and Fabric adds C2ME and Krypton for servers. Measure your own server with spark.
Can I use Fabric mods on NeoForge? Not directly. Sinytra Connector runs many Fabric mods on NeoForge, but all its builds are betas and none is out for 26.3 yet. For a server, use mods built for your loader.
Which has more mods, Fabric or NeoForge? Fabric, on Modrinth: 47,552 mods carried the Fabric tag on 31 October 2026, against 30,381 for NeoForge. The big tech mods and the All the Mods packs are on NeoForge.
Should I use Forge, NeoForge or Fabric in 2026? NeoForge for new Forge-style packs on 1.21.1 or 26.x, Fabric for light setups and new versions, Forge for packs on 1.20.1 and older.
Which Java version do Fabric and NeoForge need? The one your Minecraft version needs, as set in Mojang's version files: Java 25 for 26.1 to 26.3, and Java 21 for 1.20.5 to 1.21.11.
