What is BlueMap

BlueMap is a program that reads your Minecraft world files and generates not only a map, but also 3D-models of the whole surface. With the web-app you then can look at those in your browser and basically view the world as if you were ingame! Or just look at it from far away to get an overview.

BlueMap comes as a Spigot/Paper or Sponge Plugin, as a Fabric or Forge-Mod and you can also use BlueMap without any Server from the Command-Line as a standalone tool.

If installed as a Plugin/Mod, BlueMap renders asynchronously to your MinecraftServer-Thread. This means at no time will it block your server-thread directly. So as long as your CPU is not fully utilized, your server should not be slowed down while BlueMap is rendering.

Using BlueMap

You can download BlueMap from here.
Read the installation instructions to get started!
And here is a list of addons and tools that work with bluemap.

Here you can see how many servers are using BlueMap:

Metrics and Webserver

BlueMap uses bStats and an own metrics-system and is hosting a web-server!

Metrics are really useful to keep track of how the plugin is used and helps me stay motivated! Please turn them on :)

bStats: All data collected by bStats can be viewed here: https://bstats.org/plugin/bukkit/BlueMap/5912.

own metrics: Additionally to bStats, BlueMap is sending a super small report, containing only the implementation-name and the version of the BlueMap-plugin to my server. I do this, because there are some other implementations for BlueMap (Fabric, Forge, CLI) that are not supported by bStats. Here is an example report:

{
    "implementation": "sponge",
    "version": "5.23",
    "mcVersion": "26.2"
}

All metrics can be disabled in the plugins config.

web-server: The web-server is a core-functionality of this plugin. So it is enabled by default but can be disabled in the plugin-config. By default the web-server is bound to all network-interfaces ('0.0.0.0') on port 8100 and is hosting the content of the ./bluemap/web/-folder.

Todo / planned features

Here is a todo-list ordered by what i right now think is the priority, but might always change or be reordered at my discretion. (I develop BlueMap in my free-time, so nothing here is a promise and there are no ETA's)

5.23-spongeРелиз26.1.1, 26.1.2, 26.2 · 6 августа 2026 г.

Highlights / Notes

The integrated webserver now pushes markers and freshly rendered tile-updates to connected webapps using SSE.
And some more fixes and smaller improvements.

Upgrading from 5.22

  • Replace the bluemap.jar-file with the new one
  • Delete your <webroot>/index.html to make bluemap update the webapp

Optionally:

  • Add the following lines to your webserver.conf:
    # Whether to use Server-Sent Events (SSE) for pushing tile and marker-updates to the connected clients.
# Default is true
sse-enabled: true
  • Add the following lines to your webapp.conf:
    # This will configure the webapp to request the map-tiles compressed and decompress them manually.
# Enable this only if you intend to host the webapp statically, with an external webserver without additional configuration.
# Default is "false"
#client-decompression: true

Changelog since 5.22

  • Use Server-sent events to push updates for map-tiles, players, and markers (optional, thanks to @pR0Ps, #819)
  • Added webapp-option to decompress tiles on the client, making it possible to host the webapp statically (thanks to @fechan, #815)
  • No longer delete the whole map if no region-files exist (map might be configured incorrectly)
  • Try to resolve symlinks when loading resources
  • Added (usually hidden) config for dimension-type to fix paper-api added worlds
  • Removed native linear region format support, use the linear-addon instead
  • Track full-update-interval per-map instead of globally
  • Fixed race-condition when saving lowres-tiles sometimes corrupting them (#821)
  • Fixed live-player-markers config not being respected
  • Fixed worlds with / in dimension key not being detected correctly on paper
  • Fixed tasks sometimes not saving/loading correctly
  • Fixed in-memory region-update-timestamps not resetting on purge
