Watched shows every satellite that passed over a place
Built mostly by Claude Code, the site lists every imaging, radar, weather and crewed satellite over any location in the past week, with real Sentinel-2, Landsat and NASA imagery where it exists, on a 3D globe of about 17,000 objects.

The full story
Watched lets anyone type in a place on Earth and see every imaging, radar, weather and crewed satellite that passed over it in the last seven days, along with the actual photos where real imagery exists from Sentinel-2, Landsat and NASA. It draws all of the roughly 17,000 tracked objects on a 3D globe.
The maker brought the idea and direction; Claude Code wrote most of the code. That includes the pass-search maths using SGP4 orbits, plus a brute-force checker to prove it doesn't miss passes (no misses across 22 edge cases), a GPU shader that moves every satellite each frame, the matching of archive photos to the right pass, and most of the interface. The demo video was made with Claude Code too.
It is free, with no sign-up, and the code is public.
