Quilt Installer (1.21.5, 1.20.1) – Lightweight Mod Loader for Minecraft Java

Quilt Installer is a lightweight and modern mod loader for Minecraft Java Edition, built as a fork of Fabric with the goal of creating a more open, collaborative, and community-driven modding platform. It allows players to install and run mods effortlessly while giving developers the tools and flexibility to build complex modpacks, libraries, and plugins with ease.

Unlike traditional mod loaders, Quilt focuses on openness and modularity, empowering modders around the world to work together on shared projects. With extended documentation, plugin support, and a transparent development structure, Quilt aims to be more than just a loader—it’s a long-term ecosystem for Minecraft modding.

Key Features

• Detailed developer tools: Comes with robust debugging support, build tools, and comprehensive documentation.
