Should you build or buy Vessel Tracking & Maritime Intelligence?
Vessel tracking and maritime intelligence software combines AIS position data, satellite coverage, and sanctions or ownership records into a single feed that shows where ships are, predicts arrivals, and flags sanctioned or high-risk vessels. Buyers are carriers, commodity traders, insurers, and ports that need global ship visibility and compliance screening.
Buy the tracking and intelligence feed; build only the decision layer on top. Open AIS feeds exist for a few coastal regions, but the collection network, vessel identity history and sanctions analytics are the product, and no independent operator has replaced them in production.
Build it, buy it, or bridge?
When building makes sense
The build case here is narrow, and the evidence supports exactly that scope. Hapag-Lloyd runs a production, SageMaker-trained ETA model on top of AIS data, not on a tracking network it owns, which is the only well-documented pattern of building anything in this category. Regional open feeds, such as Digitraffic and Norway's coastal AIS feed, can support a local port dashboard covering one country's waters. What none of that reaches is global open-ocean coverage or the ability to detect vessels that have gone dark, which requires the kind of physical infrastructure and satellite constellation no team assembles from public data. Build only the decision layer: an ETA model, a berth planner, or a routing tool that consumes AIS positions. Leave the underlying tracking network to the vendors.
When buying makes sense
Buy the tracking and risk intelligence, because the thing you are actually paying for is physical infrastructure you cannot replicate. Kpler operates more than 13,000 AIS receivers across 190 countries, tracking upward of 300,000 vessels a day with satellite, terrestrial, and roaming coverage, and its 2025 acquisition of Spire Maritime folded a dedicated satellite AIS constellation into that same network for open-ocean visibility. Windward and Pole Star Global add sanctions and ownership screening on top of that positional data. Maersk and Gunvor, two of the most sophisticated shipping and trading operations in the world, integrate these vendor feeds rather than building their own, which tells you how far even a well-resourced buyer is from replacing the collection layer. Pricing is quote-based and scales with coverage, from a regional tool up to full global enterprise contracts.

Frequently asked
How much of global vessel tracking is public and free?
Very little at open-ocean scale. Regional feeds like Digitraffic and Norway's coastal AIS cover specific national waters, which is enough for a local port dashboard, but nothing free replicates satellite AIS coverage of the open ocean or dark-vessel detection.
Has any shipping company built its own tracking network?
No named carrier or trader has replaced the collection layer with a self-built network. Hapag-Lloyd built a machine-learning ETA model on Amazon SageMaker, but that model consumes AIS position data rather than replacing the tracking infrastructure behind it.
What is actually driving the cost of these platforms?
Physical collection infrastructure. Kpler operates over 13,000 AIS receivers across 190 countries and, since acquiring Spire Maritime in 2025, also owns a satellite constellation built specifically for maritime tracking; that consolidated infrastructure is capital investment no single buyer can replicate for its own use.
Where is the room to build something proprietary?
In the decision layer that consumes AIS positions: an ETA model, a berth-planning tool, or a custom risk score. That is the pattern worth copying instead of trying to rebuild the tracking network.
