NeoForge vs Fabric: Which Loader to Install, Version by Version

NeoForge is younger than most players assume. According to a post on neoforged.net dated 13 July 2023, the Discord server formerly known as Forgecord was rebranded on 12 July 2023 as a new project called NeoForged, and at the same time the NeoForged GitHub organisation forked the original Minecraft Forge project. The post, written by cpw, one of the people behind the move, states that almost all of the original Forge team joined the new project. In other words, NeoForge is not a newcomer competing with Forge's ecosystem; it is that ecosystem's development team continuing under a new name.

The first NeoForge release announcement on neoforged.net covers NeoForge 20.2 for Minecraft 1.20.2, posted on 30 October 2023. For 1.20.1, the project published builds under its old Forge artifact name: NeoForged's Maven repository lists them as net.neoforged:forge with version numbers like 1.20.1-47.1.106. From 1.20.2 onward the artifact is called neoforge and the version number tracks the Minecraft version, so NeoForge 21.1 is for 1.21.1 and NeoForge 21.11 is for 1.21.11. With Minecraft's move to 26.x numbering, NeoForge's own 26.1 announcement explains that versions now have four parts: the first three identify the Minecraft version and the last one is the NeoForge build, with a -beta suffix while breaking changes are still allowed.

Fabric describes itself on fabricmc.net as 'a modular, lightweight mod loader for Minecraft'. The important word for players is modular. The loader on its own is, in Fabric's own words, 'the bare minimum', and the site tells you to combine it with Fabric API, which must be placed in the mods folder like any other mod. Most Fabric mods list Fabric API as a dependency, so in practice installing Fabric means installing two things: the loader through the installer, and the Fabric API jar alongside your mods. NeoForge has no equivalent split; its hooks are part of the loader itself.

Version coverage is where the two differ most. Fabric's metadata service lists 48 stable Minecraft releases with Fabric support, running from 1.14 to 26.3, and Fabric's blog has a 'Fabric for Minecraft' post for every major release in between. NeoForge's coverage starts at 1.20.1 and runs to 26.3; there is no NeoForge for 1.19, 1.18 or 1.16, and there never will be, because the project did not exist when those versions were current. If the version you want to play is older than 1.20.1, the comparison is over before it starts: your options are Fabric or the original Forge.

The table below is a set of searches we ran against the Modrinth API, filtering for projects of type 'mod' that declare a given loader and a given Minecraft version. It counts what mod authors have tagged their uploads with, which is the same information Modrinth's own filters use when you browse the site.

Two patterns stand out. The first is 1.21.1, the only version in the table where NeoForge has more mods than Fabric. That fits what NeoForge's maintainers wrote when 26.1 arrived: the 26.1 release post described 1.21.1 as the version that 26.1 was likely to replace as 'the next stable modding version', and flagged that as the author's own educated guess rather than an official statement. A version that modders treat as the long-term stopping point collects ports, and NeoForge's count on 1.21.1 reflects that.

The second pattern is everything after 1.21.1. On 1.21.11, 26.1.2 and 26.3, Fabric's count is the larger one every time. 26.3 had been out for less than a month when we read these numbers (Modrinth records its release as 15 September 2026), so both columns on that row are still filling in. The low NeoForge figure on 1.20.1 has a different cause: that version predates NeoForge's own numbering, and the large back catalogue for 1.20.1 is mostly tagged as Forge rather than NeoForge. Modrinth returned 25,151 Forge-tagged mods for 1.20.1, and some of those load on NeoForge's 1.20.1 builds, but the tags alone cannot tell you which ones.

Searches for 'fabric vs neoforge performance' usually expect one loader to be the fast one. The loaders' own pages do not make that claim about each other, and we will not put a frame-rate figure on it, because no benchmark exists that we can cite. What can be checked is where the performance mods are available, and how their authors describe them.

On Modrinth, Sodium, Lithium and Iris all list the same three loaders: Fabric, NeoForge and Quilt. Sodium's author describes it as 'a high-performance rendering engine replacement for Minecraft, which greatly improves frame rates and reduces micro-stutter'. Lithium's description is 'no-compromises game logic optimization mod, useful for both single-player games and multi-player servers'. Iris is 'a modern shader pack loader for Minecraft intended to be compatible with existing OptiFine shader packs'. All three had published builds for 26.3 on both Fabric and NeoForge when we checked, and Sodium's 26.3 builds were labelled alpha on both loaders, so the newest version is equally early on either side.

That changes the shape of the question. A few years ago, choosing the Forge lineage often meant giving up the best rendering mods or relying on unofficial ports. Today the same three projects publish for both loaders directly, so a NeoForge player and a Fabric player on the same version can install the same performance stack from the same authors. Whatever difference remains comes from the rest of your mod list, not from the loader name at the top of the launcher.

If you want to know which setup runs better on your own machine, measure it. Build one profile per loader with the same version and the same performance mods, load the same world, and compare the frame counter on the F3 screen in the same spot. That gives you a number that applies to your own hardware.

Not natively. A Minecraft profile runs one loader, and a Fabric mod's jar contains Fabric-specific entry points that NeoForge does not recognise on its own. Dropping a mix of Fabric and NeoForge jars into one mods folder does not give you both sets of mods.

The one real exception is Sinytra Connector. Its authors describe it as 'a translation/compatibility layer that allows running Fabric mods on NeoForge', built so that players can 'play all their favourite mods in one modpack'. It works in that one direction only: Fabric mods on NeoForge, not NeoForge mods on Fabric. You install NeoForge, add Connector and its dependency Forgified Fabric API (described on Modrinth as 'Fabric API implemented on top of NeoForge'), and then drop Fabric mods into the mods folder. Connector has passed 26 million downloads on Modrinth.

It is, however, explicitly unfinished, and its authors are clear about the limits. Every Connector release on Modrinth is labelled beta. Its FAQ names 1.21.1 as the primary supported version that receives new fixes and compatibility improvements, calls 1.20.1 a long-term-support version that gets critical bug fixes but no compatibility fixes, and says backports to versions older than 1.20.1 are not planned. The project's home page also lists support for Fabric-exclusive mods released for 26.1.2, where its latest test build, 3.0.0-beta.6, was released on 15 August 2026. The limits the authors themselves list are:

The count table turns the choice into a version question, and most people already know which version they want. Work from the version, then from your mod list, and the loader usually picks itself.

On 1.21.1, NeoForge is a strong default. It has the larger pool on that version, NeoForge's maintainers treated 1.21.1 as the long-term modding version, and Connector is primarily supported there if you need a Fabric-only mod alongside your NeoForge mods. Large content mods that add machines, magic systems or new dimensions are the main reason people pick this combination.

On 1.21.11 and the 26.x releases, Fabric has the larger pool on every version we checked, and Fabric's blog posted its 26.3 announcement on 15 September 2026, the day Modrinth records 26.3 as released. NeoForge is not absent here: its Maven repository listed 76 builds for 26.3 on the day we checked, with the latest, 26.3.0.76, carrying no beta suffix. If the specific mods you want are on NeoForge for these versions, that is a perfectly sound choice. Note too that NeoForge's 26.1 post states Minecraft now uses Java 25, which affects anyone running the loader installers or a server by hand.

On anything older than 1.20.1, NeoForge is not an option, and the decision is Fabric or the original Forge. On 1.20.1 itself, NeoForge builds exist but most of the catalogue is tagged for Forge, so check each mod's page.

Whatever the version, the most reliable method is the one that ignores the comparison entirely. Write down the four or five mods you most want, open each one's Modrinth page, and note which loaders it lists for your version. If they agree, you are done. If they split, decide which mods matter most, or use Connector on NeoForge for a Fabric-only mod or two and accept that it is still in beta. If you are following a modpack, install the loader the pack names and skip the whole decision.
