DnD Map Maker

DnD Map Maker is a map design tool for dungeon masters and world-builders to produce grid-based fantasy maps for tabletop play. It supports dungeon interiors, caverns, cities, and outdoor regions, enabling rapid iteration with precise grid control. The underlying model treats the map as a tile grid with layered data—terrain, walls, doors, lighting, and markers—allowing both manual editing and algorithmic generation. Conceptually, the tool uses a seeded generator to produce repeatable layouts, while still permitting user-guided adjustments. This makes it ideal for DM prep, encounter planning, and teaching map-based storytelling to students. Unique value lies in seed-reproducible outputs, template-based region generation, and straightforward export workflows for print or virtual tabletop use. Core features include tile-size configuration, region templates, auto-fill for rooms and corridors, and multiple export formats (SVG, PNG, and JSON). Use cases range from a quick dungeon crawl to a full campaign world with layered regions. The tool empowers game groups to experiment with layouts, share seeds for consistent play sessions, and produce handouts or digital scenes without external software. By combining deterministic generation with flexible customization, it serves both solo world-builders and organized play groups seeking efficient, reproducible map design.
