Satlas

Satlas is a real-time 3D orbit tracker for 31,000+ objects, satellites, and debris, queryable in plain English via an AI agent. Ask when does the ISS pass over Melbourne? and it runs actual orbital mechanics, tells you the time, max elevation, and whether the sky will be dark enough to see it. Click any country to see every satellite overhead right now. Features: pass visibility scoring, category filters, country mode, and a public REST API at satlas.app/docs. No auth. Fully open source.
