In their own words
Basalt Launcher
Basalt Launcher is a free, open-source Minecraft launcher written in Rust for Linux, Windows, and macOS. It keeps saves, mods, resource packs, shaders, settings, and launch options separate for each instance. Users can install and switch among Fabric, Quilt, NeoForge, and Forge, browse Modrinth and CurseForge with compatibility filtering, dependency resolution, changelogs, and update checks, and create an instance from a Modrinth modpack. Multiple Microsoft accounts are supported with device-code sign-in and silent token refresh. Skin and cape tools allow importing, previewing, saving, and applying cosmetics. Basalt can locate compatible Java runtimes and set global or per-instance overrides. Downloads and installs can be monitored, cancelled, or recovered after interruption. Separate launcher and game logs, adjustable log levels, and launch-argument previews aid diagnosis. Installers are provided for the three desktop systems, though testing coverage varies by platform during beta. Basalt is not an official Mojang or Microsoft product.
