Pick a place. Explore it in 3D.
Choose anywhere on the world map, then walk its streets, drive a car or fly above the city. Built live from OpenStreetMap.
Time stays fixed while clouds drift and change shape. Set cloud drift to zero to stop their travel.
Your actual street, in a browser
This is the SETech engine running as WebAssembly with WebGPU, streaming live OpenStreetMap data for wherever you point it. Nothing here is a pre-built level: the roads, buildings, pavements and street furniture are fetched for the coordinates you give it, and the ground is real elevation data. Give it your own address and walk down your own road.
Streamed, not shipped
Sectors are fetched and built around you as you move, then released once you leave. The world has no edge and no load screen.
Real ground
Terrain comes from elevation tiles, so hills are the hills that are actually there. Roads are painted analytically, sharp at any distance.
Walk or take flight
Explore on foot, or press F3 to send the same third-person character into flight and survey the streamed city from above.
Controls
- Arrow keys or a gamepad move the character.
- F3 toggles third-person flight; press it again to fall back to the ground.
- While flying, use Q / E to descend or climb and hold Shift to boost.
- On a phone or tablet, on-screen controls appear automatically.
Needs a WebGPU browser: recent Chrome or Edge, or Safari 18+. First load downloads about 35 MB of engine and assets, then map data streams as you explore.
