Building in public

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.

01Framework

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.

02API

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.

03Toolchain

Automated Mappings

Deobfuscation that updates itself. When Mojang ships a snapshot, the pipeline runs. No waiting weeks for volunteers. No broken builds.

04Client

Alloy Launcher

Purpose-built launcher with native modpack support. Install, update, and launch — no manual jar shuffling, no third-party wrappers.

05IDE

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.

terminal
$alloy init my-mod
✓ Scaffolded project from template
✓ Resolved Alloy API 1.0.0
✓ Generated mappings for 1.21.4
$cd my-mod && alloy dev
✓ Compiled in 340ms
✓ Hot-reload enabled
Minecraft 1.21.4 running with my-mod@0.1.0
$alloy publish
✓ Built release artifact
✓ Published my-mod@0.1.0
$

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.
