Mapcrafter
What it is
Mapcrafter is free, GPL-licensed software that renders Minecraft worlds as images viewable in a web browser using Leaflet.js. It provides top-down 2D and isometric 3D views, four world rotations, and day, night, and cave render modes. Overlays can display information such as slime-spawn and nighttime-monster locations, while markers can be generated automatically from world data. Configuration files let users choose which worlds to render and set views and other rendering parameters. Listed capabilities include biome colors, incremental rendering, and multithreading. Mapcrafter supports offline viewing, server maps, and dimension maps. It runs on Linux and Unix-like systems such as Mac OS; Windows support is experimental. Building it requires a C++ compiler, CMake, make, and libraries including libpng, libjpeg, and Boost components, though Debian and Ubuntu packages are provided. The software requires Anvil world format and Minecraft 1.6 resource packs. The maintainer says they can no longer develop new features, though issues and pull requests may still be addressed.
