Passing By in Real Time

Passing By turns the invisible traffic of the sea into something you can feel.

Every ship within range of your location is shown as a cinematic story card — its name, its journey, its purpose. Swipe through the vessels around you and read the small narratives behind a tanker bound for Rotterdam, a tug working the harbor at dawn, or a cruise ship slipping past on its way south.

• Live vessel data, refreshed continuously over a persistent connection
• Ranked carousel that surfaces the most interesting ships first — moving cargo, named tankers, distant cruisers — instead of a wall of moored boats
• Rich detail screens with status, destination, speed, distance, and a live map
• Distances in kilometers or nautical miles
• Works in any port, harbor, or coastal city in the world
• No account required

Bring your own free AIS data key from aisstream.io for real-time vessel tracking, or explore with simulated traffic out of the box.

Passing By is for anyone who has stood at a window or a shoreline and wondered: where is that ship going?
