Bedrock Viz vs Mapee

Bedrock Viz parses Minecraft Bedrock Edition world files to create overview images and reports, and it can generate a browser-based viewer for exploring a world. The viewer covers Overworld and Nether layers, biomes, mobs and items, spawnable blocks, chunk boundaries, elevation shading, and distance measurement. It can browse 256 layers from bedrock to the build limit. Image outputs include world layers, biomes, block light, block height, and grass color; movie output is available for world layers and requires ffmpeg. The software is free and listed for Linux, macOS, web, and Windows. The README provides a Windows 10 download, supports macOS 10.15 and later through Homebrew, and directs Linux users to compile the source. Generated maps can be served locally with Docker and NGINX, or viewed offline. Running the program can change world files, so work from a backup. Locally opened viewers may lose some features because of browser restrictions, and slime chunk finding may be unreliable.
