Room to make it yours

One launcher.
Many ways to play.

01 / INSTANCES

Keep worlds separate.

Give each instance its own mods, saves, and settings. Switch between Minecraft versions without mixing your files.

02 / MODDING

Find your next favourite.

Start with Vanilla or Fabric. Browse Modrinth and CurseForge, install mods, and manage them from the launcher.

03 / YOUR SPACE

Feel at home.

Choose light or dark mode, your accent colour, language, and game settings. User data stays together in your .aluma folder.

Made in the open

A small project.
A clear direction.

Aluma is currently in development. Packaged downloads are not available yet. Microsoft account sign-in is implemented; Minecraft Services API approval is pending before online account access can work.

Authentication takes place on Microsoft's sign-in page. Aluma uses the resulting tokens to request the Minecraft profile and launch the game; it does not collect your Microsoft password.
