ABOUT THIS TOOL

Free Technology Checker — Detect CMS, Frameworks, Analytics & CDN

Free website technology checker to detect public fingerprints for WordPress, Shopify, Next.js, React, Vue, Nuxt, Cloudflare, Vercel, GA, GTM and more.

Detect CMS and frontend framework fingerprints

Toolmera looks for public signatures associated with WordPress, Shopify, Next.js, React, Vue.js and Nuxt. Signals can include asset paths, generated markup and standard framework markers that are visible in the fetched response.

Detection is probabilistic rather than exhaustive. A site can remove recognizable markers, render content differently for bots or use a framework version that does not expose the signatures this lightweight detector knows about.

Check analytics, marketing and infrastructure signals

The technology report can also identify public traces of Google Analytics, Google Tag Manager, Meta Pixel, Hotjar, Stripe, jQuery, Bootstrap, Cloudflare and Vercel. Server and generator headers are shown when the site chooses to disclose them.

This can answer practical long-tail questions such as whether a competitor appears to use Shopify, whether GTM is present in server HTML or whether Cloudflare is visible at the response edge.

What technology detection cannot reveal

A public website scan cannot reliably reveal databases, private APIs, cloud accounts, internal services or software that leaves no client-visible fingerprint. Absence from the Toolmera result means only that the current detector did not find a supported public signal.

Use the output as a research hint, then confirm important implementation decisions with documentation, source access or direct technical discovery when you control the website.

HOW IT WORKS

How to use Technology Checker

01

Enter the site or page URL

Use a public page that is likely to include the site’s normal framework, analytics and integration markup.

02

Scan public fingerprints

Toolmera checks HTML and headers for supported CMS, framework, CDN, analytics and marketing signatures.

03

Treat detections as evidence, not private access

Confirm important stack decisions separately because hidden or client-injected technologies may not expose recognizable public markers.

FAQ

Common questions

Can Toolmera detect WordPress?

Yes, when public WordPress generator or asset-path fingerprints are present in the fetched response.

Can it detect Shopify?

It looks for common Shopify CDN and theme markers visible in public HTML.

Does it detect Google Tag Manager?

Yes, common GTM script and container patterns are included in the detector.

Why might a technology be missing?

The site may hide fingerprints, inject scripts only after JavaScript execution or use a technology not covered by the current signature set.

Does the checker reveal private hosting credentials or backend code?

No. It analyzes only public response data.
