Minecraft Java 1.21.1, 1.21.3, 1.21.4, 1.21.5, 1.21.8, 1.21.10, 1.21.11, 26.1.2, 26.2 and 26.3, all with Fabric. The launcher picks the right client build for each instance.

Yes. Amethyst shows what your game already knows and never plays for you: no auto-clicking, no aim help. Some servers still ban certain kinds of mods, such as freelook or hitboxes, so check the rules of the servers you play on and switch off what they don't allow.

Amethyst is a Fabric client, so Fabric mods work next to it. Sodium, Iris, Lithium and the other usual performance mods are what the benchmarks run with. Where a mod does the same job as an Amethyst module, such as ShieldStatus or ShulkerBoxTooltip, Amethyst steps aside.

Yes. The launcher imports profiles from Lunar, Prism, the Modrinth App, CurseForge, Feather and .minecraft, and tells you what it could not bring over. It reads mod files and settings only, never the accounts or sign-ins of other launchers.

When the launcher opens, it asks amethystclient.com whether a newer version exists. Every update is signed, and the launcher installs it only if the signature and checksum match. If an update fails, the version you have keeps working, and Settings lets you go back to an earlier one.

You sign in on Microsoft's own page in your browser; the launcher never sees your password. The sign-in it keeps on your PC is encrypted with Windows' protection for your user account.

The launcher already has the code for both, and test builds are being made. They will appear on the download page once they have been tested on real Macs and Linux PCs.
