Tech Stack Analyzer

Generic SEO advice fails because the fix depends entirely on how the site was built. "Add a canonical tag" is a two-click job in Yoast on WordPress, a settings field in Shopify, and a code change in a React app. Before you spend an afternoon on a fix, it helps to know what you are standing on.

The analyzer reads the publicly served HTML and response headers and matches fingerprints: generator meta tags, script paths, cookie names, CSS class conventions, CDN headers, and asset hosts. From that it infers the CMS or framework, the hosting or CDN layer, the analytics and tag managers, and any ecommerce or marketing platforms loading on the page. Nothing private is accessed — this is exactly what any visitor's browser already downloads.

Framework or CMS tells you where your SEO controls live. Hosting and CDN tell you why your response time looks the way it does; a page served from an origin server on shared hosting will almost always be slower than the same page cached at an edge network. Analytics and tag managers are the most common source of third-party script bloat: every tag you keep "just in case" costs real milliseconds on every page load for every visitor.

Use it competitively too. Run a competitor who outranks you and look at what they are not loading. Fast sites tend to be boring under the hood: one framework, one analytics tool, self-hosted fonts, an edge cache, and very little else. If your analysis lists a dozen external hosts and theirs lists three, you have found a concrete, measurable place to win.
