Sinytra Connector: Run Fabric Mods on NeoForge in 2026

Ever felt stuck choosing between Fabric and NeoForge? You've probably picked one platform, watched your favorite mods only update on the other, and thought, "why can't I just have both?" Connector solves that problem by letting Fabric mods run on NeoForge, collapsing what used to be a hard choice into one unified setup.

What Connector Does

Here's the core deal: Connector is a translation layer. Think of it like having a universal adapter for your modded Minecraft setup. Fabric and NeoForge are two different modding platforms with different APIs, different event systems, different ways of patching the game. Connector sits in the middle and speaks both languages, so mods written for Fabric can run without modification on a NeoForge instance.

Developers only write their mod once. Players pick whichever platform they prefer. Both get the same experience.

The project has 728 GitHub stars and is maintained by the Sinytra team. It's open source under the MIT license, written in Java (as Minecraft modding usually is). Honestly, if you've ever checked Modrinth or CurseForge recently, you've probably seen mods tagged as "Connector compatible." That's what this is.

Why You'd Use This

Let's get specific. Say you run a modpack on NeoForge because you like its ecosystem, but there's a Fabric-only mod you desperately want. Without Connector, you're stuck. With it, you grab the mod, drop it in the mods folder, and it just works (most of the time, anyway).

From a developer perspective, it's even more compelling. You write your mod once. Anyone don't maintain two codebases, two versions, two bug reports. That's huge time savings.

The modding community was sort of split between these two platforms for years. Some developers went Fabric because of its cleaner API design. Others preferred NeoForge for its larger corporate backing and different feature set. Players caught in the middle had to pick a platform and live with whatever mods supported it. Connector closes that gap.

It's also useful if you're building a custom server and want maximum flexibility. Need that specific Fabric utility mod plus that NeoForge admin tool? Connector lets you mix and match instead of rebuilding around platform constraints.

How to Set It Up

Installation is straightforward. First, you need NeoForge installed. Go to neoforged.net, grab the latest stable version, and run the installer (just like you would with Forge).

Once that's done:

1. Download Connector from Modrinth or GitHub Releases
2. Drop the JAR file into your mods folder
3. Also download the Forgified Fabric API (it's a separate download, and Connector needs it to run)
4. Launch the game

That's really it. No special configuration files. No environment variables to set. It's designed to feel like installing any other mod.

# If you're managing installs via command line, it looks like this:
# 1. Install NeoForge
# 2. Download Connector JAR
# 3. wget https://github.com/Sinytra/Connector/releases/download/.../connector-version.jar -O mods/connector.jar
# 4. Download Forgified Fabric API JAR into the same folder
# 5. Launch with your usual Java command

The Forgified Fabric API is basically what it sounds like: the Fabric API ported to work on NeoForge. Connector needs it as a dependency, so don't skip that step (I almost did, and yeah, nothing loaded until I grabbed it).

Key Features That Matter

Connector isn't just a simple compatibility wrapper. So it does some real heavy lifting under the hood.

Automatic event translation. Fabric and NeoForge have completely different event systems. Connector maps Fabric events to NeoForge equivalents on the fly. You don't see this happening, but it's what makes the whole thing possible. A Fabric mod that listens for "ServerTick" events gets automatically wired to the NeoForge equivalent.

Mixin handling is another big one. Both platforms use Mixins for patching the game, but they apply them differently. Connector sorts this out so Fabric mods' Mixins don't conflict with NeoForge's runtime environment.

API compatibility. Fabric has a lot of utility APIs (for blocks, items, networking). Connector provides NeoForge implementations of these so mods that depend on the Fabric API don't break when running on NeoForge.

There's also built-in support for Connector Extras, which is a separate project that handles trickier third-party library compatibility. If you're running mods that depend on unusual libraries, Extras smooths out potential conflicts. It's optional but worth knowing about.

Common Issues and How to Avoid Them

Not every Fabric mod works on Connector. The project maintains a compatibility database that shows which mods have been tested. Always check there before adding a new mod to your instance.

Some mods depend on Fabric-specific libraries or use very deep Minecraft internals in ways that don't translate. You'll know this happened because the mod either won't load or will crash immediately. The compatibility database usually flags these.

Version mismatches between Connector and your NeoForge version can cause subtle issues. Make sure you're grabbing the Connector release that matches your NeoForge version. The GitHub releases page is pretty clear about which version supports which NeoForge build.

One thing that tripped me up: if you've a modpack that mixes Fabric and Fabric-adjacent tools (like Mod Menu, for example), you need the NeoForge equivalents instead. The game won't error, but features might be missing. Check the mod's page on Modrinth to see if it explicitly supports Connector.

The community Discord is active and helpful. If a mod isn't working, you can ask there and usually get an answer quickly about whether it's a known compatibility issue.

Alternatives Worth Knowing About

Connector isn't the only cross-platform mod solution, though it's the most mature one for Fabric-to-NeoForge specifically. Some developers just maintain separate codebases using shared libraries, but that's more work. Others have moved to NeoForge entirely as it's gained adoption.

There are also platform-agnostic modding frameworks emerging, but they tend to require opt-in from mod developers. Connector is valuable because it works with existing Fabric mods without requiring the developer to change anything.

Before You Jump In

Connector is genuinely impressive from a technical standpoint. It's not a hacky workaround; it's a serious engineering project that handles a surprisingly complex compatibility problem. That said, it's not magic. Some mods won't work, and debugging why can be frustrating.

If you're setting up a server and want to use specific mods from both ecosystems, Connector is worth the 10 minutes it takes to set up. Check the compatibility database, grab the downloads, and see if it solves your problem. For most people, it'll save you from having to choose between mod ecosystems.
