In plain English

Fantasy Map Generator is a free web application for creating and editing detailed fantasy maps. You open it in a browser at azgaar.github.io/Fantasy-Map-Generator, no installation required. It is aimed at fantasy writers, game masters, and cartographers who want maps for stories, tabletop roleplaying games, or personal projects. The application builds maps using procedural generation, meaning it produces landscapes, regions, rivers, cities, and other geographic features automatically. Once a map is generated, users can edit it interactively. The tool is described as highly customizable, and the project wiki provides guidance on how to use it. The creator also maintains a blog with background notes on the project. There is an active community around it. A Discord server and a Reddit community give users a place to share maps, suggest ideas, and get updates. The creator tracks ongoing development on a public Trello board. Bug reports go through GitHub issues or a dedicated Discord channel. The project wiki includes performance tips for users who encounter slowdowns. The codebase is written in JavaScript and is being gradually converted to TypeScript. Pull requests are welcome for contributors, though the creator notes the codebase is messy and recommends starting with minor changes. The long-term architectural goal is a separation into four layers: world data and styles, procedural generators, interactive editors, and a renderer. Each layer has a defined role. The renderer is meant to be a pure visualization step that does not modify the underlying world data. The project draws on several published articles about procedural terrain and map generation. It is free to use, and the creator accepts financial support through Patreon.

Copy-paste prompts

Prompt 1

I'm using Fantasy Map Generator at azgaar.github.io. How do I customize the generated regions and city placements to better fit my fictional world?

Prompt 2

Help me write a description of a fantasy world based on this map: [describe your generated map's key features]. Make it suitable for a novel introduction.

Prompt 3

I want to contribute to the Fantasy Map Generator open-source project. The codebase is JavaScript being migrated to TypeScript. Suggest small, beginner-friendly areas to start with.

Prompt 4

Using Fantasy Map Generator, I've created a map with mountains, rivers, and kingdoms. Help me design a political conflict between two neighboring kingdoms based on their geography.

Prompt 5

Explain the four architectural layers of Fantasy Map Generator, world data, procedural generators, interactive editors, and renderer, and how I should think about extending or modifying each.
