What Users Say About MarineTraffic
“Service terminated without notice after Kpler acquisition. Had to pay more than double for the same service.”
“Costs add up fast—satellite, analytics, vessel count—it is all separate billing.”
“The satellite systems and availability of data APIs support our startup in delivering solutions that generate value.”
“Would almost call it a scam—other free sites provide exactly the same. MarineTraffic costs $900 USD per year.”
