Launchpad
Porting a Fabric mod to NeoForge used to mean weeks of rewriting metadata, reworking entrypoints, and untangling dependency chains. Launchpad changes that equation entirely. This lightweight compatibility layer lets you run Fabric-style mods on NeoForge without a full native port, making it a favorite tool among mod developers who want results without the grind.
What Is Launchpad for Minecraft?
Launchpad is a small tool designed for developing NeoForge mods using Fabric conventions. Instead of forcing you to abandon everything you built for Fabric, it bridges the gap by reading your existing mod structure and translating it into something NeoForge can understand. Think of it as an adapter rather than a rewrite.
The add-on handles several core tasks automatically:
- Reading mod metadata from fabric.mod.json files
- Running mod entrypoints, both standard and custom
- Access transformation using Class Tweakers or Access Wideners
- Loading nested jar dependencies
On top of the Fabric standard, Launchpad adds its own extensions documented in its usage guide, giving developers extra flexibility when the default behavior is not quite enough.
Supported Versions and Loaders
Minecraft Versions
Launchpad targets modern Minecraft releases that align with current NeoForge builds, typically covering the 1.20.x and 1.21.x lines. Because it depends on the Forgified Fabric API, you should always check that your chosen Minecraft version has a matching Forgified Fabric API release before you download Launchpad. Running mismatched versions is the fastest way to crash on startup.
Loader Compatibility
This is a NeoForge-only tool. It does not run on Fabric, Quilt, or Forge. That might sound odd given its Fabric roots, but the entire point is to bring Fabric conventions into the NeoForge ecosystem. If you are already building natively for NeoForge, you do not need it.
When Should You Use Launchpad?
Launchpad shines in specific scenarios. It works best for small to medium-sized Fabric mods that are already potentially compatible with NeoForge and just need that final push to load properly.
Reach for it when:
- You want to port your mod to NeoForge but lack time for a full native port
- Your mod needs little to no changes to work with NeoForge, particularly regarding Mixins
- You are comfortable adding extra dependencies, namely the Forgified Fabric API and Launchpad itself
If you maintain a sprawling mod that leans heavily on NeoForge APIs, wants full control over metadata and entrypoints, or simply cannot tolerate extra dependencies, a native port or the MultiLoader template will serve you better. Launchpad is a shortcut, not a replacement for proper architecture.
How to Install Launchpad
Getting started is straightforward. First, confirm you are running a compatible NeoForge version for your Minecraft release. Next, place the Forgified Fabric API jar into your mods folder, since Launchpad depends on it. After that, add the Launchpad jar itself. Launch your game through your NeoForge profile, and the loader will pick up both files during startup.
For developers testing in a workspace, the setup mirrors a standard NeoForge development environment, with the extra step of including Launchpad as a dependency in your build configuration. Full instructions live in the project repository, which is worth reading before you attempt anything ambitious.
If you would rather skip manual file juggling, the foxygame.net launcher streamlines the whole process: it bundles Launchpad alongside its curated add-on catalog, so a single click installs the right build for your exact Minecraft version and keeps it updated automatically.
Common Pitfalls to Avoid
Most Launchpad failures trace back to three causes: a missing Forgified Fabric API, a version mismatch between Minecraft and NeoForge, or metadata that assumes full NeoForge behavior. Double-check your fabric.mod.json entries and confirm your Mixins do not rely on Fabric-specific hooks that NeoForge handles differently.
It also helps to test with a clean instance. Conflicts with other mods that transform classes can produce confusing errors that have nothing to do with Launchpad itself.
Final Thoughts
Launchpad fills a genuinely useful niche. It is not trying to be a universal bridge or a permanent solution for every project, and that honesty is part of its appeal. For developers with modest Fabric mods who want them running on NeoForge quickly, it removes hours of tedious work while keeping the door open for a proper native port later. Download Launchpad, pair it with the Forgified Fabric API, and see how far a small compatibility layer can carry your project.
