Watabou Github Io

watabou github io is a free, browser-based collection of procedural map generators created by indie developer Oleg Dolya. Better known as Watabou's Procgen Arcana, this small corner of the web has become one of the most trusted resources for tabletop role-playing game enthusiasts, dungeon masters, worldbuilders, and fantasy writers who need beautiful maps without paying for heavy design software. What makes watabou github io stand out is that everything runs directly in your browser: there is nothing to install, no account to create, and no subscription to remember. You simply open the page, pick a card, and a brand-new map is generated for you on the spot.

The collection includes a wide range of generators that cover almost every scale a fantasy campaign needs. The Realm generator produces continent-scale maps with coastlines, mountain ranges, rivers, and political borders. The City generator creates detailed urban maps with streets, districts, walls, and landmarks that look like they belong in a printed campaign setting. The District generator zooms in further, producing neighbourhood-scale maps, while the Village generator crafts small rural settlements with fields, cottages, and local roads. For adventurers heading underground, the Cave/Glade generator builds organic cave networks and forest clearings, and the Dungeon generator lays out room-by-room floor plans ready for encounters. The Dwelling and Mansion generators round out the set with individual buildings, from humble homes to grand estates. In short, watabou github io covers realms, cities, districts, villages, caves, dungeons, dwellings, and mansions under one simple interface.

Each generator exposes a handful of thoughtful settings so you can influence the outcome: map size, randomness seed, density of features, and other thematic options. Press the button again and you get an entirely different map, which makes the tool perfect for rapid brainstorming during a session. Because it is a static, dependency-free site, watabou github io loads quickly and never nags you with ads or pop-ups. The project has been maintained since 2022 through 2026, with an FAQ section and news updates confirming that it is a living, actively cared-for hobby project.

Whether you are preparing a one-shot dungeon crawl, building a whole homebrew world, or just exploring algorithmic art, watabou github io is a delightful, zero-cost addition to your toolbox. It is highly recommended for game masters, indie TTRPG designers, and anyone who loves maps.
