MarineTraffic

History: This service started as a community-driven project and has grown into one of the world’s most popular ship tracking and maritime intelligence platforms.
Functionality: It provides real-time positions of hundreds of thousands of vessels worldwide using AIS data. Users can see ship types, destinations, speed, and photographs, offering a live view of global maritime traffic.
Future Plans: MarineTraffic continues to innovate with a recent redesign for a more map-centric interface and aims to enhance data coverage and user experience, including more detailed port information and historical data analysis.
