As answered by people managing Eloquent JavaScript and BigOceanData.
BigOceanData's answer:
BigOceanData combines global satellite and terrestrial AIS vessel tracking with the operational tools maritime teams need to act on that data. Rather than simply showing vessel positions, the platform brings together live fleet monitoring, configurable alerts and zones, vessel and track history, port visibility, maritime intelligence and route optimisation in one environment. It is built to scale with customers and supported by people who understand maritime operations, with the product roadmap shaped by real customer requirements.
BigOceanData's answer:
BigOceanData is designed for organisations that need more than a public ship-tracking map. It offers global AIS coverage across more than 450,000 vessels, satellite tracking included across plans, flexible alerts and zones, historical tracking, shared team access, port visibility and clear operational reporting. Customers can start with vessel tracking and expand into route optimisation and maritime intelligence as their requirements grow, while retaining access to responsive support from maritime subject-matter experts.
BigOceanData's answer:
BigOceanData is primarily built for commercial maritime organisations that need reliable vessel visibility and operational intelligence. Typical users include ship owners, fleet operators, ship managers, marine operations teams, maritime security and intelligence teams, insurers, logistics and chartering organisations, ports, agencies and public-sector users. The platform is particularly well suited to organisations managing fleets of roughly 5 to 250 vessels, while also supporting larger and more complex monitoring requirements.

Seconded. I won't recommend it and no one I know has recommended it for a decade. It's hard for someone who doesn't know JS to know which parts has changed and is no longer the way to do things. https://github.com/getify/You-Dont-Know-JS... - Source: Hacker News / about 2 years ago
