When you look at a website, it's often useful to know what it runs on, whether you're a developer, a marketer or doing sales research. Many detectors give you a list of logos with no reason behind each one, and some send the pages you visit to a server. We built one that shows the evidence for every result and does its detection inside your browser.

We only show reviews that real users posted on a browser store, quoted word for word with a link to the review. We don't write, buy, swap or ask for reviews in exchange for anything, and we don't use testimonials, star ratings or user counts from anywhere else.
