Maritime Vessel Intelligence (AIS) 🚢

Live AIS vessel tracking + ship intelligence for the Baltic Sea / Northern Europe — straight from Finland's official Digitraffic service. No API key, no proxy.

Get a live snapshot of vessels at sea, each merged with its identity: position, speed, course and navigation status combined with vessel name, IMO, ship type, destination, draught and ETA. AIS/vessel data is normally paid and locked behind commercial APIs — this uses a fully open government feed.

Perfect for maritime logistics & port ops, supply-chain visibility, shipping analytics, research and journalism, and vessel-monitoring apps.

Uses Digitraffic (Finnish Transport Infrastructure Agency) — no key, no login. Coverage: Baltic Sea / Northern Europe (the area Digitraffic receives AIS for).

Modes

• 🛰️ Live vessel positions — every currently-tracked vessel with position + identity.
• ⚓ Port calls — recent/scheduled port call records.

Features

• ✅ No API key, no proxy — open government AIS feed.
• ✅ Position + identity in one row — name, IMO, type, destination, not just coordinates.
• ✅ Decoded — ship-type category, navigation status and AIS ETA decoded to readable values.
• ✅ Filters — by MMSI, ship-type category, bounding box, or moving-only.

Input

Field	Description
Mode	positions / port-calls.
MMSI list	Track specific vessels, e.g. ["230099950"].
Ship type categories	Cargo / Tanker / Passenger / Fishing / ….
Moving only	Only vessels under way (speed > 0.5 kn).
Bounding box	minLat / maxLat / minLon / maxLon.
Max results	Cap on records.

Example — moving cargo & tankers

  "shipTypeCategories": ["Cargo", "Tanker"],
  "movingOnly": true
}

Run it on a schedule

Run every few minutes to build a track history for your fleet or a sea area — pipe to a database, map or webhook for live monitoring and ETA prediction.

Notes & limitations

• Coverage is regional (Baltic Sea / Northern Europe) — this is a Finnish government feed, not global AIS.
• AIS is self-reported by vessels; some fields (destination, ETA, occasionally speed) can be stale or inconsistent — values are passed through faithfully.
• Data source: Digitraffic / Fintraffic (CC BY 4.0). Attribution appreciated.
