biomed is a free Minecraft biome editor for Java world saves. Users can select a biome and apply it to a map with Fill or Draw tools, then switch between biome and map views. Its Fix Snow/Ice tool adjusts snow and ice for warm and cold biomes. A world can be opened through the File menu or by selecting its region directory, and saved from the menu after editing. The listed capabilities focus on biome changes and include batch operations; terrain and entity editing are not included. biomed supports Minecraft world saves containing level.dat and a region directory, and runs on Linux, macOS and Windows. Precompiled downloads are listed for 64-bit Linux and 32-bit Windows, and GTK 2.x is required. The README advises backing up maps before making changes. The MIT license permits use, copying, modification, distribution, sublicensing and sale subject to its conditions, and provides the software without warranty.
