Aisstream Plans Pricing
AISStream.io is free. There is a single access tier: register for a free API key and stream real-time global AIS data over the WebSocket at no cost. There are no paid, developer, or enterprise tiers and no per-message billing. Consumption is scoped by the subscription (bounding boxes plus optional MMSI and message-type filters) under a fair-use model rather than a purchased quota.
