MultiMC
What it is
MultiMC is an alternative launcher for Minecraft that keeps game setups in separate instances. Each instance can have its own mods, resource packs, and saves, and instances can be imported or exported as MultiMC .zip files for sharing. It imports modpacks from Modrinth, CurseForge, FTB, Technic, ATLauncher, and FTB legacy, and includes a built-in modpack catalog. The launcher also manages Minecraft worlds and resource or texture packs, provides control over Java settings and runtimes, and displays color-coded logs with added diagnostic information. It can update automatically and lets users stop Minecraft if it crashes or freezes. MultiMC is free and runs on Windows, macOS 10.13 or newer, and Linux distributions; Linux may require Qt5 and distribution-specific packages. The project is designed to run in the background, including on older machines. Its code is hosted on GitHub, and users can contact the team on Discord, though the team says it is often busy. A listed Patreon support option is priced on request.
