Wappalyzer
Wappalyzer identifies technologies detectable on websites visited through its browser extension.
Use it for a quick initial view of a site's visible technology stack.
CMS, ecommerce and other detections can guide research without manually inspecting every page asset.
Keep in mind: Detections are signals, not a complete architecture audit or proof of a security weakness; hidden, changed or obscured technology can be missed.
