A world from a seed
The same seed always gives the same world: terrain, rivers, climates, biomes, countries, cultures and cities.
AIM MapsBeta
Generate a whole world map from a seed and make it your own: terrain, countries, cities, routes, names and styles.
Free, no sign-up, no card.

For game masters, novelists, game makers and teachers who bring invented worlds to history and geography.
AIM Maps opens in a browser tab: nothing to download, install or update.
AIM Maps is free and complete, with no time limit and no card.
AIM Maps works in your browser: your files never leave your computer.
What you export with AIM Maps comes out clean, with no watermarks.
The same seed always gives the same world: terrain, rivers, climates, biomes, countries, cultures and cities.
Paint the terrain, move borders, add cities and routes, and rename countries, cities and regions.
Turn layers on and off (terrain, borders, routes, labels, grid…) and pick an illustrated style or make your own.
More than thirty typefaces for the names on the map, included in the app.
PNG and JPEG at the scale you choose, and SVG to keep editing in AIM Vector.
Save the map as a .map project and open it later to carry on where you left off.
Nothing is uploaded. Work saves itself and comes back if you reload the page.
AIM Maps runs inside your browser: it opens and saves on your computer. Your files are never uploaded to a server and nobody else sees them.
AIM CREATE belongs to Biomag, a Spanish technology company since 1987. The website and accounts run on servers in the European Union.
Not even on the free plan: what you export is yours, as it is, and video goes up to 4K.
Free forever. CREATE Plus is optional: €1.99 a month on the yearly plan (€23.88 a year) or €2.49 a month paid every 6 months, VAT included.
Yes. The maps you create are yours, commercial use included.
A number that fixes the generated world: share it and someone else gets the same map.
No. Everything happens in your browser and nothing is sent to any server.
