BlueMap vs MCA Saenk

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.

MCA Saenk is a Windows top-down rendering mapper for Minecraft that produces screenshots and can export them as in-game maps. It renders 3D shading from multiple angles and can reproduce the look of in-game maps when settings are calibrated. Styles include default, Java map, Bedrock map, and betaplus, with custom styles possible from resource packs and mods. The tool handles semi-transparent blocks, filtering, and custom blocks, biomes, and dimensions from mods and datapacks. More than 30 settings cover contrast, lighting, shading, colormaps, biome blending, and water translucency, with many adjustments using hardware acceleration. A virtual screenshot window can be dragged and scaled before capture. Official Java releases from 1.2.1 through 26.2 are supported, while Fabric and Forge modded-world support is an aim. OpenGL rendering requires version 4.0 and falls back to legacy rendering when unavailable.
