What Freesm Launcher is
Freesm Launcher is free Minecraft launcher software for Linux, macOS, and Windows. As a Prism Launcher fork, it removes offline account restrictions, supports custom authentication servers, and adds customization options. Offline mode works without signing in with a Microsoft account, while Ely.by provides another authentication choice and can display Minecraft skins without mods or plugins. The launcher supports separate instances, manages Java runtimes, and updates automatically. Its feature list includes FTB pack support. Users can choose dark or light themes with Fluent icons and Catppuccin or Rosé Pine colors. Animated GIF cat packs, image cropping, animated snow, and random username or instance icon selection provide additional changes. It can copy in-game screenshots into buffer history without mods. The project describes itself as FLOSS under GPL-3.0, says it does not collect user information, and accepts bug reports and contributions through GitHub Issues. Stable packages and a NixOS Flake are available; development builds may contain bugs or instability.
