About DMapper

DMapper is a web-based grid mapping tool for 3D dungeon games.

It operates entirely client-side without requiring a server and stores data in the browser's local storage.

Each dungeon consists of multiple floors (B1F to B100F), allowing you to create independent maps for each floor.

Each dungeon can have individual grid size settings, and you can manage multiple dungeons simultaneously.

Perfect for mapping Wizardry-like games and similar dungeon crawlers.
