Why Is This Website Slow? is a simple website performance checker for normal users.
Click the extension icon on any page to see a clear explanation of what may be slowing the site down. It shows large JavaScript files, possible ad and tracker requests, redirect chains, and the biggest images loaded by the page.
The extension is designed to be readable, not overly technical. It gives quick labels like “large script,” “possible tracker,” or “large image” so users can understand what is happening without opening Developer Tools.
All analysis happens locally in your browser. The extension does not send your browsing history, page data, URLs, analytics, or scan results to any external server.
