GrabDiff is a visual uptime monitoring tool that takes scheduled screenshots of your URLs, compares them pixel-by-pixel, and alerts you when visual changes or failures occur. It helps website operators catch issues like blank pages, broken layouts, or CDN errors that HTTP monitors miss. The platform offers a free plan and supports multiple languages.
GrabDiff sits in PulseGate's Observability & monitoring category. It focuses on detecting visual website failures and changes that traditional uptime monitors miss. GrabDiff is a B2B product aimed at website operators. There is a free tier, and paid plans start at $19. It runs on the web.
GrabDiff first shipped in 2024. Among its 9 catalogued features are screenshot diffs, visual monitoring, and pixel comparison. The interface is available in 5 languages, including Danish, English, and Finnish.
