One ecosystem.
Zero compromises.
Alloy is a complete Minecraft modding stack — custom framework, launcher, toolchain, and IDE — engineered together from a blank page. Every layer talks to every other. Nothing is bolted on.
The full picture
Others give you a mod loader.
We built the entire stack.
Every existing modding platform is a patchwork — a loader here, a community-maintained mapping there, three competing launchers, and an API designed by committee a decade ago. Alloy is one integrated pipeline where every piece was designed to work with every other piece.
Custom Mod Loader
Not a fork. Not built on Forge, Fabric, or Quilt. A clean-room mod loader designed for how Minecraft actually works today — fast classloading, zero legacy overhead, built for modern JVMs.
Modding API
A single, coherent API surface. Event-driven, well-typed, documented from day one. No guessing which of three deprecated methods is the right one.
Automated Mappings
Deobfuscation that updates itself. When Mojang ships a snapshot, the pipeline runs. No waiting weeks for volunteers. No broken builds.
Alloy Launcher
Purpose-built launcher with native modpack support. Install, update, and launch — no manual jar shuffling, no third-party wrappers.
Dev Environment
Gradle plugin, project templates, hot-reload, integrated debugging. Idea to running mod in minutes, not hours of environment wrestling.
Developer experience
Idea to running mod.
Three commands.
Not incremental
What this actually means
The current state
- Pick a loader. Hope it supports the version you need.
- Find community mappings. Wait for updates.
- Three different launchers, none designed for modding.
- API designed around Minecraft 1.7. In 2025.
- Documentation scattered across wikis, Discord pins, and blog posts from 2019.
With Alloy
- One loader, always current. Version support is automated.
- Mappings update themselves when Mojang ships.
- A launcher built for mods — install, update, launch.
- API designed for modern Minecraft, modern Java.
- Documentation is a first-class deliverable, not an afterthought.

We're building Alloy in public. The code is open, the roadmap is transparent, and we ship every week. Come build with us.
