The same rail you get in the app

Five places. The icons are the launcher’s 12 by 12 pixel set.

  • Home

    Open the instance you played last.

  • Library

    Every instance you keep, ready to launch.

  • Discover

    Browse Modrinth and install into a chosen stack.

  • Accounts

    Microsoft sign-in, or offline profiles.

  • Settings

    Java, theme, gamepad, Discord presence, and the rest.

A cairn marks the trail. An instance does the same.

Stack the game, loader, and content, then come back to it. New profile, Modrinth App import, or an .mrpack.

  1. Build the stack

    Pick Minecraft and a loader, or pull in a folder you already have.

  2. Add Modrinth content

    Mods, resource packs, shaders, and datapacks go into the instance you choose.

  3. Launch and return

    Home opens what you played last. Worlds, servers, and logs stay on that stack.

Screens from the real build

Basalt chrome. Lichen for play. Moss when something is running or installed.
