Raitsikat shows every Helsinki tram on a live map in real time. The data comes from HSL's public MQTT feed (High-Frequency Positioning), so trams move on the map exactly as they move on the street.
Filter the view by line and click a tram to see its route. Runs in the browser with no signup, and installs as a PWA.
