How To Use
Choose a preset from the menu or define custom conditions. Pick an anchor position such as world spawn, origin coordinates, or custom coordinates. Use the condition builder to add requirements for biomes, structures, or terrain height. Press the search button to dispatch work to background web workers. Matching seeds appear in the results list alongside interactive preview thumbnails.
Troubleshooting
If no seeds match your configuration, review the active criteria to ensure constraints do not conflict. Expanding the search radius or lowering the required feature count allows candidates to qualify more quickly. You can stop or resume the search process at any point using the main action control.
Known Limitations
Calculations run locally in your web browser utilizing WebAssembly. Complex searches involving multiple features across large distances require more processor time. Selecting a higher grid sampling setting prioritizes faster scanning over granular biome border detection.
