A Minecraft world downloader that works as a proxy server between the client and the server to read & save chunk data. Download multiplayer worlds by connecting to them and walking around. Chunks can be sent back to the client to extend the render distance.
Latest Windows release (GUI): world-downloader.exe
Cross-platform jar (GUI & command-line): world-downloader.jar
Download the latest release and run it. Enter the server address in the address field and press start.
Instead of connecting to the server itself, connect to localhost in Minecraft to start downloading the world.
If you run into any problems, check the FAQ page for some common issues.
- Requires no client modifications and as such works with every game client, vanilla or not
- Automatically merge into previous downloads or existing worlds
- Save chests and other inventories by opening them
- Extend the client's render distance by sending chunks downloaded previously back to the client
- Overview map of chunks that have been saved:
