what aircraft is overhead?
live demo: https://whatsoverhead.rickt.dev
front and backend src for a simple "what aircraft is overhead" app.
backend is python, uses the free adsb.fi ADS-B API, i deployed to GCP Cloud Run but you can put it wherever.
frontend is simple HTML + JS.
inspiration for this came from John Wiseman's whatsoverhead.com, which i loved! i wanted to know how it works and ended up writing my own version.
