BlueMap
What it is
BlueMap reads Minecraft world files and turns them into 3D surface maps that can be viewed in a browser. It supports Java Edition worlds, not Bedrock Edition. You 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, including through Docker as described in its documentation. Plugin and mod installations render asynchronously to the Minecraft server thread, with a configurable render-thread count. After the first conversion, BlueMap tracks world changes and converts only changed chunks. Maps can be stored in files or an SQL server. Configuration options cover map display names and web app ordering, while map configuration files can add or remove maps. Its API supports feature integration by third-party plugins, mods, resource packs, and external tools. The integrated webserver does not support SSL, and BlueMap does not provide authentication itself; the FAQ points to an external webserver for those functions. BlueMap is free. Plugin and mod use requires Java 25 or later; the standalone CLI documentation lists Java 21 or later.
