JumpQuilt
Minecraft modding has always been about choice, but sometimes the launcher you use dictates which mods you can enjoy. If you have ever wanted to combine the convenience of a CurseForge modpack with the lightweight power of Quilt mods, JumpQuilt is the bridge you need. This clever utility hijacks the Forge loading process and replaces it with Quilt, letting you run Quilt mods in environments that normally only support Forge. It is a direct fork of the popular Jumploader, which performed the same trick for Fabric before CurseForge added native Fabric support.
What Is JumpQuilt?
JumpQuilt is a specialized mod that allows the use of Quilt mods inside CurseForge modpacks by loading Quilt as if it were a Forge mod. It does not enable Forge and Quilt mods to run side by side. Instead, it completely takes over the launch sequence so that Forge never actually loads. This means you can enjoy the Quilt ecosystem—known for its speed and modularity—without leaving the familiar CurseForge app. The mod only activates when your game is launched from Forge or ModLauncher, so it stays dormant if your Minecraft launcher already supports Quilt natively.
How JumpQuilt Works
When you start Minecraft through a Forge profile, JumpQuilt intercepts the process early. It loads Quilt instead of Forge, automatically fetches the latest Fabric loader version for your game release, and ensures that Quilt and Mixin do not see the classes loaded by ModLauncher. If necessary, it also loads the unpatched vanilla Minecraft game so that Quilt can attach cleanly. The result is a seamless experience where your modpack thinks it is running Forge, but in reality, Quilt is handling all the mods.
Key Features and Limitations
JumpQuilt brings several important capabilities to the table, but it also has clear boundaries. Understanding both will help you avoid lost worlds and broken saves.
- Automatic loader installation: On first launch, JumpQuilt downloads the latest Quilt loader for your Minecraft version. No manual configuration is required.
- Forge-free environment: It completely prevents Forge mods from loading. Any blocks, items, or entities added by Forge mods will vanish if you open a world that previously used them.
- Smart activation: The mod only runs when launched through Forge/ModLauncher. If your launcher already supports Quilt, JumpQuilt does nothing.
- No Forge-Quilt hybrid: You cannot run Forge mods and Quilt mods together. For that, you would need a project like Patchwork.
- Configurable loader version: You can pin a specific Quilt loader version by editing the
pinQuiltLoaderVersionproperty in thejumpquilt.jsonconfig file.
How to Install JumpQuilt for Minecraft
Installing JumpQuilt is straightforward, but you must take precautions. Because it stops Forge mods from loading, always back up your worlds before joining any save that previously used Forge mods. All custom blocks and items from those mods will disappear permanently.
To install, simply place the JumpQuilt JAR file into your mods folder like any other Forge mod. The mod requires a Forge version that uses ModLauncher, which typically means Minecraft 1.13 or newer. Once added, launch the game through your Forge profile. JumpQuilt will detect the environment and swap in Quilt automatically. If you ever need to update the Quilt loader manually, open the config file and set the desired version number.
For those using the foxygame.net launcher, JumpQuilt appears in the add-on catalog with automatic version matching, so you can install it without manual configuration and keep it updated effortlessly.
Download JumpQuilt and Get Started
You can download JumpQuilt from its official distribution channels. Look for the latest release that matches your Minecraft version. Since the mod is a fork of Jumploader, it inherits a stable codebase and a straightforward update policy. Remember that JumpQuilt does not automatically update the Quilt loader after the first install to prevent breaking existing modpacks. If you want a newer loader, you must edit the config file or delete it to trigger a fresh download.
Compatibility and Supported Versions
JumpQuilt works with any Forge installation that relies on ModLauncher, covering Minecraft versions from 1.13 up to the latest releases. It is compatible with both the standard Minecraft launcher and third-party launchers that use Forge profiles. Because it only loads when ModLauncher is present, you can safely keep it in your mods folder even if you sometimes launch with a native Quilt profile—it will simply stay inactive.
The mod is designed for CurseForge modpacks, but it can be used in any Forge-based setup where you want to switch to Quilt. Just be mindful of the one-way nature: once you open a world with JumpQuilt active, all Forge-specific content is gone. Always make a backup first.
Conclusion
JumpQuilt fills a specific niche for modpack creators and players who prefer Quilt mods but rely on the CurseForge ecosystem. By silently replacing Forge with Quilt, it opens the door to a faster, more modular modding experience without forcing you to abandon your favorite launcher. Whether you are building a lightweight pack or simply experimenting with Quilt, JumpQuilt for Minecraft is a tool worth adding to your modding toolkit. Just remember to back up your worlds, and you will be ready to explore a new side of Minecraft modding.
