AstroAlert is your personal sky-watch assistant. It tells you exactly which satellites, planets, comets, and deep-sky objects will pass right above your location in the next 24 hours — including spectacular zenith events above 70°. Powered by NASA/JPL data, it combines real-time calculations with educational content, a full astronomy glossary, and detailed object sheets. The sky above you, revealed with precision.
This is quite amazing. How do you know the location? Do you ask for location permission?
@chilarai Thank you! 🙌
Yes — the app asks for location permission the very first time, but it's entirely optional after ! You can disable it.
Did you vibe code it? With which tool?
@pasha_tseluyko Not really “vibe coded” 😄
I used a mix of tools: FlutterFlow for the app, Firebase for the backend, and a lot of Python running on my VPS for all the orbital calculations.
ChatGPT helped a ton along the way, but everything is fully custom-built.
@budb Haha true, that’s actually a really good name! 😄
I hesitated a lot while naming the app — maybe I’ll keep Satalert in mind for a future feature or companion tool!
Thanks for the idea! 🚀
