A live harbor/ship tracker. Set a location on a map (your own position, or anywhere you're
curious about), and see live AIS ship positions nearby — name, speed, heading, destination, ETA,
vessel type, call sign, IMO number, all in a click-through modal per ship.
Ship data comes from AISStream.io, a free network of volunteer
terrestrial AIS receivers. A small Cloudflare Worker holds the one live upstream connection and
merges position/static data by ship, so any number of visitors can watch the same harbor without
each opening their own connection.
Coverage is terrestrial, not satellite — ships well offshore or far from a receiver may not
appear, which the app itself notes.
