Documentation

What the launcher does and how, one topic per page. Everything comes from the official repository: README and release notes.

Instances

Own version, loader, mods and worlds. One never interferes with another.
Mods, shaders and packs

Mods, resource packs, shaders and data packs from Modrinth and CurseForge, dependencies resolved.
Modpacks

Install from the catalog, a .mrpack or a .zip; update without losing your changes; export any instance.
Worlds and maps

Your worlds with .zip backups, ready-made maps from CurseForge and each instance's screenshots.
Skins and capes

Change skin, model and cape on your Microsoft account; offline profiles keep the skin in the launcher. 3D viewer.
Accounts

Official Microsoft login, credentials in the system keychain. Offline profiles for servers that allow them.
Automatic Java

The right runtime for each version, downloaded from Mojang when missing.
Performance

Opens fast and uses little memory. Each instance gets a check that suggests the right memory in one button.
Compatibility

Java, loader and version verified before launch. Whatever doesn't match becomes a warning with the button that fixes it.
Errors explained

When the game closes with an error, the launcher reads the log, recognizes the cause and offers the fix in one click.
Updates

Hash checked on every download. The launcher announces new versions and only installs signed packages.
Dedicated servers

Create and manage a vanilla, Fabric, Quilt, Forge or NeoForge server, and open it to friends over the internet.
