Luna Launcher
What Luna Launcher is
Luna Launcher is a free, open-source Minecraft launcher for Linux, macOS and Windows. It organizes separate game instances, each with its own mods, resource packs and settings, and it can install and launch modpacks while managing Java runtimes. Built-in Terracotta and YukariConnect support is intended to let friends connect without port forwarding or complicated network setup. A toolbar preview shows server status and player information and offers one-click joining. Per-instance LunaUI panels can be written in JavaScript or JSON to read instance state and toggle mods. Community mirror APIs such as BMCLAPI can accelerate downloads, but that support remains in development and may fail in some cases. Launching and managing Minecraft servers from the launcher is also in development. The maker describes Luna Launcher as an early version that may lack stable installation packages, recommending source builds or preview Releases. Code uses GPL-3.0-only; logo assets use CC BY-SA 4.0.
