Worldsmith
Worldsmith is a free, open-source browser application for generating fantasy world maps from a numeric seed, with a mode for rendering real Earth. Procedural terrain uses domain-warped fractal noise, including ridged mountain ranges, while biomes derive from elevation, moisture, and temperature. Rivers use D8 flow accumulation to form tributary drainage networks. Exports include PNG maps up to 5120 pixels, editable SVG maps up to 3840 pixels, JSON world data, and 8-bit or 16-bit heightmaps. The maker says heightmaps can be imported into Unity, Unreal Engine, Blender, and World Machine. Earth mode uses NOAA ETOPO1 elevation and bathymetry, averaged to about five kilometers per sample; synthesized detail is disclosed and can be disabled with Detail set to 0. The app runs entirely client-side without an account, server, or dependencies, and is offered under the MIT license.
