What is the Technology Detector?

Every website runs on a stack of technologies — a CMS, a frontend framework, a CDN, analytics tools, advertising pixels, payment processors. Most of this is invisible to the casual visitor but detectable by analyzing the page's HTML, JavaScript files, HTTP headers, cookies, and network requests.

The Technology Detector scans any public website and identifies the technologies it's built with, organized by category. It's a fast way to research how a competitor is built, understand a client's tech stack before a project, or learn what powers a site you admire.

How to Use the Technology Detector

1. Enter the website URL — the full URL including https://.
2. Run the scan. The tool fetches the page and analyzes its source, headers, and scripts for technology fingerprints.
3. Review the results. Detected technologies are grouped by category — CMS, frameworks, analytics, hosting, CDN, security, and more. Where version numbers are detectable, they're included.

What Gets Detected

Content Management Systems — WordPress, Shopify, Webflow, Squarespace, Ghost, Drupal, and others leave identifiable traces in page structure, meta tags, and file paths.

JavaScript frameworks — React, Vue, Angular, Svelte, Next.js, Nuxt, and similar frameworks expose identifiers in their rendered markup, script file names, or runtime globals.

Analytics and tracking — Google Analytics, Google Tag Manager, Facebook Pixel, Hotjar, Mixpanel, and other tracking scripts are identified by their known snippet patterns and domain endpoints.

CDN and hosting — Cloudflare, Fastly, AWS CloudFront, Vercel, Netlify, and other providers leave traces in HTTP response headers (Server, Via, X-Powered-By, CF-Ray, etc.).

E-commerce platforms — Shopify, WooCommerce, Magento, BigCommerce, and similar platforms are detectable from URL structures, cookie names, and checkout flow patterns.

Security and WAF — Cloudflare WAF, Sucuri, Wordfence, and similar tools can be detected through response headers and injected scripts.

Advertising platforms — Google Ads conversion tags, Facebook/Meta Pixel, TikTok Pixel, LinkedIn Insight Tag, and similar advertising scripts are identified by their known source URLs and initialization patterns.

Detection Confidence

Not all detections are equally certain. Some technologies announce themselves explicitly (a X-Powered-By: WordPress header is definitive). Others are inferred from patterns that are strongly associated with a technology but not exclusive to it. The tool indicates confidence level where relevant.

Version detection is available when the technology embeds version information in its script files, HTML comments, or meta tags — which many CMS platforms do, though production-hardened sites often strip or obscure this.

Common Uses

Competitor research — understand what CMS, e-commerce platform, analytics tools, and marketing stack a competitor is running. This informs technology decisions and helps identify their tooling investments.

Client onboarding — before starting work on a client's site, quickly understand what they're running — which hosting, which CMS version, which plugins or integrations.

Technology evaluation — research how companies in a specific space or size range are solving common problems (what analytics tool do most SaaS companies in this category use?).

Security auditing — identify outdated technology versions that may have known vulnerabilities, or detect tracking scripts that shouldn't be present.

Learning — see how well-known sites are built and what technology choices are common in specific industries.

Limitations

The tool analyzes only publicly accessible page content. Technologies used exclusively in backend systems, server-side rendering that leaves no client-side trace, internal tooling, and private API infrastructure are not detectable. Login-protected pages and sites that block crawlers cannot be analyzed.

Privacy

Scans are run against publicly accessible pages only. No personal browsing history or identity is associated with scan results. Results are not stored.
