Turn any road on Earth into a Grand Prix circuit, then watch a full grid of 22 cars race it. GeoPrix is a racing simulator and race track builder on real streets. Draw a circuit on the map — your street, a mountain pass, a coastal road — or race a legend like Monaco, Baku, Macau or the Nürburgring Nordschleife. GeoPrix snaps it to the real road geometry, measures every corner and the true width of every street, and simulates the whole race. DRAW ANY CIRCUIT Search for a place or tap points on the map. GeoPrix follows the real roads between them and closes the loop, working out the corner radii, the braking zones and where a car can realistically overtake. A SIMULATED RACE, NOT A LAP A full grid of 22 lines up, the lights go out, and every car is simulated from the start to the chequered flag: overtakes, retirements, safety car periods, and a running order that actually changes. Narrow streets run single file; wide boulevards let cars race side by side. Watch it live on the map, or skip ahead to the result. 19 LEGENDARY CIRCUITS Monaco, Baku, Macau, the Nordschleife, Le Mans and more, ready to race on their real streets. EXPORT A REEL Turn a race into a video you can share — a captioned highlight reel of the best moves, or the full race from lights out to flag. BUILD YOUR GRID Eleven teams, twenty-two drivers, all of them yours to rename and recolour. NO ACCOUNT, NO SERVER There is no sign-in, and GeoPrix never asks for your location. Circuits, results and your grid live on your device. GeoPrix is free and supported by ads, with races up to 20 laps. One optional purchase, GeoPrix Pro, removes every ad, unlocks full-race exports and lets races run up to 99 laps, for good.
