Visual regression check: diff a page against the last run
Rigel
Screenshots a URL and compares it pixel by pixel with the PNG of the previous run (pixelmatch). Returns percentChanged and a diff image. The first run only stores the baseline, in a named store of your account. Schedule it daily and alert on percentChanged. Example: example.com. About $0.003 for the first run, then $0.004 with the diff.
