What the launcher does

Two catalogs, one launcher

Modrinth and CurseForge in one place. Find it, install it, play — no app-switching.

Modpacks that install in full

Even big CurseForge packs download complete — including mods you'd otherwise grab by hand.

Every instance, its own way

Per-instance version, mod loader, memory and Java. Switch between them with no conflicts.

Microsoft or offline account

Play via Microsoft, or create an offline account. Both work — you don't need premium to run it.

Java sorts itself out

The launcher downloads and picks the right Java per instance. Nothing to install by hand.

Always up to date

Updates install themselves on launch, with a changelog.
