MultiMC 0.9

MultiMC is a free, open-source launcher for Minecraft that makes it easy to create, organize, and customize multiple isolated game instances. Developed by the MultiMC Contributors, it gives you fine-grained control over each setup—versions, mod loaders, mods, resource packs, saves, Java settings, and more—without mixing files or configurations between them.

Key features:

• Manage multiple instances side by side, each with its own worlds, settings, and screenshots
• Install and switch between Minecraft versions, including snapshots
• Simplify modding: add or remove mods per instance and use popular mod loaders like Forge and Fabric
• Import and export modpacks; compatible with common modpack formats
• Choose the Java runtime per instance and configure memory and JVM options
• Review detailed logs with a built-in console and crash reporting
• Sign in with Microsoft accounts and select profiles
• Cross-platform support for Windows, macOS, and Linux
• Lightweight and portable, with no background services

Whether you’re testing new mods, keeping a clean vanilla build, or sharing a ready-to-play pack, MultiMC streamlines your Minecraft workflow.
