Obstruction Checker

Upload a sky photo — we detect obstructions and estimate Starlink viability. 100% local, no data leaves your browser.

How to take the photo

  1. Stand where the dish will mount
  2. Point your phone straight up
  3. Use the widest lens available (0.5× on iPhone)
  4. Capture the full sky circle
  5. Take it around noon for clearest sky color

What we analyze

Pixel luminance + hue classification → sky vs obstruction ratio. This is a quick-check heuristic, not a replacement for the official Starlink app's satellite-path simulation. Use both for final install decisions.
