Free, standalone learning tools · built with the Gillby API

The water has a story.
Find it in the data.

See what you can build with Florida water data. These public demonstrations live outside the signed-in planning app. No Gillby account is needed; choose a question and explore the available evidence.

Built with the same public API you can use.

Each experiment requests Gillby’s public HTTP API and exposes its request URLs, source metadata and a repeatable MCP workflow. Charts and calculations run in your browser. Available data, rate limits and coverage vary. These are learning tools, not navigation or swimming advice.
