## What it is
A browser-based tool that procedurally generates American-style city maps with images exportable as PNG or SVG and 3D models exportable as STL files. It offers both automated generation and step-by-step manual control over the map creation process.

## Use cases
- generate procedural city maps for tabletop RPGs
- create fictional American-style city map images
- export 3D printable city models as STL files
- make stylized map graphics like Google or Apple maps themes
- generate hand-drawn sketch style city maps
- automate city map generation for game assets

## When to choose
- you need fictional city maps for games, stories, or D&D campaigns
- you want 3D-printable city models from generated maps
- you need fine-grained control over each stage of map generation
- you want map images in multiple visual styles including sketch themes

## When to avoid
- you need real-world geographic map data or routing
- you need a programmatic map-generation library to embed in your own app
- you need non-American-style city layouts or non-city terrain
