Technical SEO / Competitor Research
Website Technology Stack Detector
See what a site is actually built on — CMS, e-commerce platform, SEO plugin, page builder, CDN, cache layer, analytics and more — straight from its live HTML and response headers, with the exact evidence for every finding, confirm can.
Fetches the homepage one time only and checks its HTML and HTTP response headers — no crawling, no login needed one.
What this tool checks
Every site leaks clue about what it is running on: a meta generator tag, a CDN header, a JavaScript global, a session cookie name, a script path. This tool fingerprints a live page against a signature library covering CMS, e-commerce platforms, JS frameworks, SEO plugins, page builders, CDNs, web servers, caching layers, analytics tools, support widgets, payment processors and bot-protection services — then explains what each one means for your SEO.
Why this matters for SEO
Knowing a site's stack tells you what is actually possible for it lah. A WordPress site running Yoast has different sitemap and meta-tag behaviour from one running Rank Math. A Shopify store has structurally different canonical and pagination issues from a hand-built React app. Before you audit a competitor, migrate a client, or diagnose a rendering problem, knowing the stack saves a lot of guesswork.
How confidence is graded
Every match got real evidence behind it, never a guess. A technology is marked Confirmed when two or more independent signals agree (for example, a script path AND a matching HTTP header). One matching signal only is marked Likely — still solid evidence, just from one source instead of two. Expand any result to see exactly which signal fired.

Frequently asked questions
Same as Wappalyzer or BuiltWith or not?
Same idea — passive fingerprinting from the page a browser would see — but a much smaller signature set that is SEO-focused. It checks one live fetch of the homepage against signatures for technologies that really change how a site behaves for search: CMS, SEO plugin, e-commerce platform, CDN, cache layer and JS framework.
Why check homepage only?
One fetch keeps the tool fast, predictable, and light on the target server, and the homepage almost always represents the whole site's stack — same CMS, theme, plugins and CDN serve every page one. If a site genuinely mixes stacks (an old blog on WordPress next to a headless storefront), run this tool separately on each URL.
Can a site hide its technology stack from this tool?
Can — removing generator meta tags, renaming default asset paths and stripping identifying headers all reduce or remove what this tool can see. That is good hardening practice anyway: same move also denies the same fingerprinting to anyone scouting the site for known vulnerabilities in a specific CMS or plugin version.
Why some results say "Likely" and not "Confirmed"?
Confirmed means two or more independent signals agree — for example a script path and a matching cookie. Likely means only one signal fired. Both are real matches, not guesses; Likely results just rest on one piece of evidence instead of two, so treat as strong hint, not certainty can already.
Does this tool keep the URLs I check?
No page content is stored. The scan runs live for your request only; see the site privacy policy for the general logging that applies to every tool on this domain.
