One toolbox, fully stocked

Mod loaders
Forge, NeoForge, Fabric or Quilt. Pick one per instance and Flux handles the install.
Instances
Every install keeps its own mods, saves and settings — nothing bleeds into the next one.
Accounts
Sign in with Microsoft, play on an offline profile, or log in with Ely.by — skins included.
Modrinth
Search, browse and install mods and modpacks without leaving the launcher.
Skin preview
Rotate and zoom your skin in 3D before you launch, powered by skinview3d.
Logs
Every launch is logged. When something crashes, the reason is one click away.
