For another alternative to FlightAware, you could look at Sabre. Sabre is a large technology platform that offers a variety of solutions to the travel industry. That includes data analytics, departure control, inventory management and network planning tools that airlines can use and that can be used to monitor flight schedules. Sabre employs modern technologies like AI and real-time data analytics to deliver better customer experiences and optimize operations, so it's a good option for managing flight data in one place.
Another option is Ably. Ably is a real-time digital experience platform that offers APIs to build powerful apps. That includes features like real-time data broadcasting, data synchronization and GPS location tracking. That last feature could be useful for tracking flights and broadcasting their location in real-time, similar to FlightAware's live tracking feature.
If you're interested in weather and aviation, Tomorrow.io offers hyper-accurate weather data and forecasts. Its weather resilience platform includes real-time weather data, historical weather APIs and predictive workflows. That can be useful for companies that need to deal with weather problems and optimize operations accordingly, like airlines and airports.
These alternatives offer a variety of features that can help you manage and analyze flight data, as FlightAware does.
