Driftopolis is an infinite procedural city visualizer — a generative skyline you can drift through forever. Tune density, lighting, fog, palette, and camera to shape your own ambient focus environment, then export a 4K wallpaper of any moment you like.
Driftopolis is a free procedural 3D city visualizer that runs in your browser. It generates an infinite ambient skyline you can drift through, with controls for density, lighting, fog, palette, and camera. It works as a focus background, a desktop screensaver replacement, and a 4K wallpaper generator. No account, no signup, nothing leaves your device.
Yes. Completely free, no hidden limits, no account required, no watermarks, no feature gates. Everything runs locally in your browser using JavaScript and WebGL. Settings and exported wallpapers stay on your device.
Open the page and the city starts drifting on its own. Drag to rotate the camera, scroll or pinch to zoom, click or double-tap the canvas to randomize. Open the settings panel from the top-right icon to tweak density, sun angle, fog, palette, and more. Hit Capture 4K Wallpaper to export a 3840×2160 PNG of the current view.
No. Everything runs locally in your browser. Your settings, exports, and any imported state files never leave your device. There are no servers, no uploads, and no tracking beyond basic anonymous page analytics.
Yes. Open Driftopolis full-screen and leave it running for an ambient screensaver-style experience. For a true desktop wallpaper, use Capture 4K Wallpaper to export a still image at 3840×2160 and set it as your background. Tools like Lively Wallpaper on Windows can pin Driftopolis as an animated live wallpaper. Need an animated alternative? Try Cosmic Forge or Neotropolis.
Any modern browser with WebGL — Chrome, Edge, Firefox, or Safari, on desktop or mobile. Performance scales with your GPU. On a recent laptop or phone it runs smoothly at full quality; on older hardware, lower the density or window size for a steadier framerate.
Pixel City is Shamus Young's classic procedural city screensaver from 2009 — Windows-only download, no live controls. Driftopolis is the spiritual successor that runs in any browser with no installation, on any operating system. It adds runtime controls for density, lighting, sun angle, fog, palette, and 4K wallpaper export that Pixel City does not offer.
Yes. Use Export State in the settings panel to download a JSON file with every parameter that defines the current city. Import State loads it back on the same device or another one. Share the JSON to share your exact city look.
Yes. The interface is touch-aware. One-finger drag rotates the camera, two-finger pinch adjusts the field of view, and double-tap randomizes the city. The settings panel is fully responsive for narrow screens.
