Mod MixinBootstrap

MixinBootstrap, Mixin support for Forge

MixinBootstrap is a small Forge library mod that provides a temporary, unofficial way to start SpongePowered Mixin in a MinecraftForge production environment. It does not add blocks, items, biomes, or gameplay systems. Instead, it supplies the bootstrap layer required by some older mods that use Mixin to modify Minecraft classes during startup.

Designed for Minecraft Java Edition, it supports Forge releases from 1.12.2 through 1.17.1 and can run on both clients and servers. Because it is a transitional solution, compatibility depends on the modpack. Our BoxToPlay team treats it as a technical dependency that can help a Minecraft server load legacy Forge content reliably.
