About UI Testing Inspector

An extension that finds visual regressions. It shows real changes and stays quiet about everything else. Take a baseline of your page. Make your changes. Click Compare. The report shows only what actually changed. Why the report stays clean 🔸 The extension compares your page to a baseline. Overlaps that were always part of the design are not errors. 🔸 Carousels, banners, timers and ads are detected and excluded automatically. Nothing to configure. 🔸 Tested on real websites. Thousands of false positives from pixel tools drop to zero here. Privacy Screenshots and data never leave your computer. No cloud, no accounts, no subscriptions. What is in the report 🔸 A one-line verdict. You see right away if the page is fine. 🔸 Findings in plain language. For example, "a block overlaps a button". Each one comes with a screenshot crop and a highlight. 🔸 Text changes. Before and after, with changed words highlighted. 🔸 A slider to compare the baseline with the current version, plus a difference map. 🔸 Export the report as a single file with all screenshots. Send it to a client or teammate. It opens without the extension. Responsive audit 📱 Check your page at 320, 768, 1024, 1440 or your own widths. The report shows where the layout breaks and includes a screenshot for every size. It can also 🔸 Capture the whole page, including the part below the fold 🔸 Spot clipped text and blocks that stick out of their containers 🔸 Flag accessibility issues, such as images without descriptions 🔸 Keep your last 10 reports. Reopen any of them anytime How it works 1️⃣ Open your page and take a baseline 2️⃣ Change your code and content 3️⃣ Click "Compare with baseline".
