The Quilt Project is a modern, open source, free, and lightweight mod loader for Minecraft since version 1.18.2, forked from the similar Fabric Project. If you use Fabric, Forge, vanilla, or OptiFine on a day-to-day basis when playing on 1.18.2, I would recommend checking out Quilt.
Quilt forked from Fabric for a good number of reasons, the primary of which was due to lack of proper moderation or administration. A good portion of the rationale for Quilt forking can be found in this gist.
