LumilioCL
A native Minecraft launcher with no Electron or WebView. Create Vanilla, Fabric and Quilt games, import modpacks, install mods from Modrinth and CurseForge, let it manage Java, map worlds from saves or seeds, and preview Litematica schematics in 3D.
LumilioCL
LumilioCL is a native Minecraft launcher written in Rust with GPUI and GPUI Kit. There is no Electron or WebView: the interface, the downloads, the world map and the 3D schematic preview are all compiled code. It runs on macOS (Apple silicon), Windows 10 and 11 (x64) and Linux (x64), with the interface in English and Simplified Chinese.
Game library
Create Vanilla, Fabric or Quilt games, or bring games over from MultiMC, Prism and .minecraft without changing the original files. Modrinth .mrpack, CurseForge and MultiMC / Prism modpacks import directly. Favorites, collections and search keep a large library in order, and snapshots, full backups and modpack export protect each game.
Discover
Browse mods, resource packs, shaders and modpacks from Modrinth and CurseForge inside the launcher. Filter by game version and loader, and install straight into the current game; downloads and their progress appear in Activity.
World map
Draw the surface of a world from its saved Region files, or predict structure locations from the seed alone. Structure, chunk and Region layers can be turned on and off, coordinates can be copied, and waypoints are shared in a format that Xaero's Minimap understands.
Litematica schematics
Open Litematica schematics, read the material list and export it as CSV, or look at the build in 3D with the game's own textures, either orbiting it or flying through it in first person. The schematic studio can also replace blocks, convert schematics between game versions, find duplicate files and restore earlier copies.
Help when the game crashes
When a game crashes, the launcher reads its logs and crash report, states the probable cause in one sentence and suggests a fix, with the technical details one step further. The full analysis can be copied with personal details removed.
