Fantasy Map Generator is an open source tool by Azgaar. You may use auto-generated maps as they are, edit them or even create a new map from scratch. Check out the Quick start, Q&A, Video tutorial, and hotkeys for guidance.

Join our Discord server and Reddit community to ask questions, get help and share maps. The created maps can be used for free, even for commercial purposes.

The project is under active development. Creator and main maintainer: Azgaar. To track the development progress see the devboard. For older versions see the changelog. Please report bugs here. You can also contact me directly via email.
