Linux build available now
Every loader. Every account.
One launcher.
Forge, NeoForge, Fabric and Quilt without the launcher-juggling. Sign in with Microsoft, play offline, or bring an Ely.by account. Built because the stock launcher wasn't enough.
One toolbox, fully stocked
Every piece you'd normally bounce between launchers for, built into one.

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.
Up and running in two lines
$ chmod +x Flux-Launcher.AppImage
$ ./Flux-Launcher.AppImageWindows and macOS builds are on the way. Building from source today? npm install && npm run build:linux gets you there.
