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.

QSL and QFAPI for 1.20.6 and beyond


July 3, 2024

QFAPI is out now for 1.20.6 and 1.21. However, the version of QSL (the Quilt-only tools we provide developers) bundled in these versions is much smaller than before, and currently only contains the qsl_base and crash_info modules. More APIs will be reintroduced to QSL as time goes on. This means that mods written using Quilt Standard Libraries may need extra work to be ported to 1.20.6 and beyond, while Fabric mods for these versions will work fine. Additionally, delays on updating to new versions should be significantly shorter in the future.

More importantly, however, you may have noticed that this is the second blog post in two days! That's not even enough time for Eminem to write another song. This is because rai (your usual blog post correspondent) now has competition! If she doesn't turn in the next monthly blog post on time, I'm replacing her with an AI trained on speeches given by members of the Canadian Parliament. What could go wrong?

Quilt Development Update: April, May & June 2024


July 2, 2024

Welcome back to the blog, quilters. It's been three months since the last time I wrote up one of these big update posts, three months since you skipped to the parts you cared about without reading my whole post, and one month since Eminem released a new Slim Shady song and took away my chance to start this post with a "guess who's back" joke. Which is fine. I'm not mad. Not even a little. Let's see what happened with Quilt in the last few months!

Quilt Development Update: March 2024


April 8, 2024

In my journeys through the many QuiltMC codebases, I've learned many things. One of those teachings is that I should keep this intro short and sweet. This month saw tons of work on QSL, a big release of Quilt Loader, and a ton of new mappings. Simply delightful. Grab your machete, and I'll show you the path to enlightenment via learning about updates to our block game modding toolchain.
