Acknowledgements

Early development of this product was inspired and informed by the open-source project FlightWeatherWatch by ligolnik, used under the MIT License. The current codebase was written independently and differs substantially; we gratefully acknowledge the prior work.

FlightWeatherCheck is built with open-source software, including React, Next.js, Radix UI, Tailwind CSS, Lucide, and amazon-cognito-identity-js on the web side, and Python libraries including httpx, boto3, the Anthropic SDK, cryptography, and the Stripe SDK on the server side — used under their respective MIT, BSD, and Apache-style licenses. We're grateful to their maintainers and contributors.

Briefings are assembled from public data published by the National Oceanic and Atmospheric Administration (NOAA), the National Weather Service, the Aviation Weather Center, and the Federal Aviation Administration — including the FAA's VFR chart tile services and 28-day NASR aeronautical data. This public data infrastructure is what makes a service like this possible. FlightWeatherCheck is not affiliated with or endorsed by NOAA, the NWS, or the FAA, and is a supplemental tool only — never a replacement for an official briefing.
