To use dungeon finder, enter your world seed in the text box at the top and click "Find Dungeons!". Afterwards, you can use the map below to find chunks that contain dungeons:
- Multiple Spawners in chunk
- Zombie Spawner
- Skeleton Spawner
- Spider Spawner
To get the exact coordinates:
- mouse input: hover over a chunk or double click
- touch input: tap or long press on a chunk
Then, the coordinates will be displayed below the map.
How accurate is it?
The finder is not 100% accurate. Some of the locations may not be actual dungeons in-game, and some in-game dungeons may be missing. My goal is that the finder is accurate enough to be useful and not be frustrating to use.
If you find multiple locations to be wrong, try again in a distant location. If that doesn't help, let me know in the comments. Also post your world seed, the locations you checked and your Minecraft version.
For technical reasons, you need to know the seed of your world to use Dungeon Finder, unless, of course, you want to find a seed for a new world. If you're playing SSP, the app is able to fetch the seed from your savegame. Alternatively, you can use the /seed command ingame. In SMP, you can use the same command if you have sufficient rights. Otherwise, however, you're dependent on the server owner, who started the world and has access to the savegame and config files.
This app uses some relatively new web technologies. As a result, some features may be disabled for older browsers. I recommend using the latest version of a major browser such as Chrome, Firefox, Edge or Safari.

The first thing you should do is select a seed and version. You can either type it in manually, or you can load it from your savegame. The latter can be done by clicking on "Load from Save..." and selecting your level.dat, or by drag&dropping the level.dat file into your browser window. Level.dat is a small file located in the folder of every Minecraft savegame. You can find the savegames in the saves folder of your Minecraft installation. On Windows you can use %appdata%\.minecraft\saves to get to that folder.
You should also know that a seed is always a number (up to around 20 digits). If you type in anything else (like letters), it will be converted to a number. The app does this the same way Minecraft does, so it's safe to use letters (and other characters) as well.
