BlueMap
What BlueMap is
BlueMap reads Minecraft world files and produces 3D surface maps that can be viewed in a browser. It supports Java Edition worlds, not Bedrock Edition. Users can install it as a Spigot, Paper, or Sponge plugin, or as a Fabric or Forge mod; it can also run from the command line without a Minecraft server. Documentation describes using the CLI in Docker. For plugin or mod installations, rendering runs asynchronously to the Minecraft server thread, and users can configure the number of render threads. After the initial conversion, BlueMap tracks world changes and converts only changed chunks. Maps can be stored in files or an SQL server. Configuration includes map display names and web app ordering, and map configuration files can add or remove maps. An API allows third-party plugins, mods, resource packs, and external tools to integrate features. The integrated webserver does not support SSL, and BlueMap itself provides no authentication; an external webserver is suggested for those functions. BlueMap is free. Server plugin and mod use requires Java 25 or newer, while the standalone CLI documentation lists Java 21 or newer.
