Introduction

Meow Craft Launcher (mcl) is a native Minecraft: Java Edition desktop launcher built with Go and MyGo.

It is designed to keep Minecraft instance management fast, predictable, and self-contained without a browser runtime or bundled telemetry.

What mcl includes

• Isolated instances — Each instance keeps its own mods, resource packs, shader packs, saves, and loader configuration.
• Five runtime environments — Vanilla, Fabric, Quilt, Forge, and NeoForge.
• Integrated resource market — Search, filter, and install mods, shaders, resource packs, data packs, and modpacks from Modrinth and CurseForge.
• Modpack import & repair — Import .mrpack (Modrinth) and .zip (CurseForge) archives into isolated instances, with local fallback for restricted CurseForge files.
• Automatic Java & memory handling — Probes local Java runtimes, installs matching Eclipse Temurin JDK/JRE builds when needed, and sets architecture-safe memory bounds automatically.
• Unified accounts — Supports official Microsoft OAuth sign-in alongside offline profiles.
