The Quilt Project

The Quilt project is an open-source, community-driven modding toolchain designed primarily for Minecraft. By focusing on speed, ease of use and modularity, Quilt aims to provide a sleek and modern modding toolchain with an open ecosystem.

Quilt is a project that was born out of a need for change in the Minecraft modding ecosystem. Our teams contain many experienced members of the modding community, providing a level of familiarity that helps us to avoid the mistakes of the past -- whether those mistakes relate to community management, diversity and inclusivity, project governance or transparency. For more information on how we hope to do this, please see our "about" pages.


Quilt is currently in beta. Here be dragons -- there may be issues, but we'll fix them as quickly as we can!

If you'd like to help us test Quilt, please feel free to install it, try it, and let us know how you get on!


Quilt is community-driven, and couldn't exist without its users and contributors. We care about our community; whether you're a member of our community spaces, an occasional contributor to one of our projects or simply a user: Quilt exists for your needs -- not in spite of them.


Quilt has the extra features and tools your mods need to succeed. From a rich library of modules that help you to write more compatible mods with less effort, to one of the most accurate decompilers provided by any Minecraft modding toolchain, you can be sure that your mod is in good hands.

Quilt Loader Telemetry Explained


July 12, 2023

Update 17/07/2023: The beacon has been temporarily disabled following a report that it was errorneously storing IP addresses. Please see this forum post for more information.

Quilt Loader 0.19.2 adds beacon functionality to count Quilt's Monthly Active Users, or MAUs. There has recently been some confusion about how this functionality works and why it was added, so this blog post is intended to provide a clear explanation of both of those things.

July 9, 2023

The Quiltflower decompiler is an integral part of Quilt's toolchain, and has been quietly developed by jaskarth and the rest of the Decompilers team since our earliest beginnings. Yesterday, the team decided to separate from Quilt and continue development under the Vineflower organisation.
