Bedrock Viz vs BlueMap

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.

BlueMap reads Minecraft Java Edition world files and turns them into 3D surface maps that people can view in a browser. It can run as a Spigot/Paper or Sponge plugin, a Fabric or Forge mod, or a standalone command-line tool without a Minecraft server. The CLI documentation also covers Docker use. Plugin and mod installations render asynchronously relative to the Minecraft server thread, and the render-thread count is configurable. After the first conversion, BlueMap tracks world changes and processes only changed chunks. Maps can be stored in files or an SQL server. Configuration files can add or remove maps, with settings for display names and web app ordering. An API lets third-party plugins, mods, resource packs, and external tools integrate features. BlueMap is free: the listed plan is free. Server plugin and mod use requires Java 25 or later; the standalone CLI documentation lists Java 21 or later. BlueMap does not support Bedrock worlds. Its integrated webserver has no SSL or built-in authentication; the FAQ suggests using an external webserver for those functions.
