Website technology checker
What is a website technology detector?
A website technology detector — sometimes called a technology checker, tech stack checker or technology lookup tool — examines public signals from a website to identify the software it appears to use. Those signals can include HTML, response headers, script and stylesheet URLs, cookies, metadata and public platform endpoints.
WebBuildFinder turns those signals into a readable website tech stack report. Instead of stopping at a single CMS name, it looks across the platform, frontend, backend, marketing and infrastructure layers so you can understand how a site is put together.
CMS & ecommerce
Identify WordPress, Shopify, WooCommerce and other content management or ecommerce platforms when they expose reliable public fingerprints.
Frontend frameworks
Check for React, Next.js, Vue, Nuxt, Angular, Svelte, JavaScript libraries, CSS frameworks and UI component systems.
Backend & languages
Surface public clues for technologies such as PHP, Node.js, Python, Laravel, Django, Rails, Express, ASP.NET and related server frameworks.
Analytics & marketing
Find Google Analytics, GA4, Google Tag Manager, advertising pixels, customer-data tools, marketing automation and live-chat software.
Hosting & infrastructure
Look for CDN, cloud, PaaS and web-server signals including Cloudflare, CloudFront, AWS, Vercel, Netlify, nginx and LiteSpeed.
Commerce & security
Detect public payment, authentication, CAPTCHA, cookie-consent and security technologies such as Stripe, PayPal, Auth0 and Turnstile.
Practical website research
Why check what technology a website uses?
Knowing a website's visible technology stack can speed up competitor research, technical audits, rebuild planning, prospect qualification and platform decisions.
SEO & growth
See analytics, tag managers, marketing automation, consent tools, structured data and performance technologies before planning an audit.
Development
Identify frontend frameworks, UI libraries, backend frameworks, programming languages, build tools and hosting clues before a rebuild.
Competitive research
Understand which ecommerce platform, themes, apps, plugins, payments and infrastructure competitors expose publicly.
Sales & agencies
Qualify prospects by CMS, ecommerce system, page builder, analytics, CDN, hosting and visible integrations before outreach.
Migration planning
Create an early inventory of the public technology surface before moving a website to Shopify, WordPress or a custom stack.
Security awareness
Spot public WAF, CAPTCHA, authentication and infrastructure signals as context for a broader security review.
Website tech stack checker
Identify the full website tech stack, not just the CMS.
A modern website is usually made from several layers. WebBuildFinder checks the platform as well as the frameworks, libraries, analytics, marketing tools, CDN, hosting clues, payments, authentication and other publicly visible technologies around it.
- Frontend and backend technologies in one report
- Platform-specific theme, app and plugin details
- Evidence and confidence shown for each detection

Shopify & WordPress detector
Detect Shopify themes and apps, or WordPress themes and plugins.
When the scanner confirms Shopify or WordPress, it automatically runs platform-specific checks in the same report. There is no need to switch between separate theme, app and plugin detector tools.
- Shopify theme name, Theme Store ID and visible storefront apps
- WordPress theme metadata, child/parent theme and visible plugins
- Unknown public plugin slugs are still surfaced instead of discarded

Framework & language detector
Find JavaScript frameworks, CSS frameworks, backend technologies and programming languages.
For developers and technical researchers, WebBuildFinder looks beyond the visible page builder for public clues that point to frontend frameworks, UI systems, build tools, backend frameworks, runtimes and programming languages.
- React, Vue, Nuxt, Next.js, Angular, Svelte and more
- Tailwind, Bootstrap, Vuetify, Material UI, Ant Design and more
- Laravel, Django, Rails, Express, NestJS, ASP.NET and more
- PHP, Node.js, Python, Ruby, Java, Go and Elixir signals

Analytics & marketing detector
Detect analytics, tag managers, advertising pixels and marketing tools.
A website technology audit is more useful when it shows how the site measures and markets, not only how the page is rendered. WebBuildFinder checks for common analytics, tag-management, advertising and marketing technologies.
- Google Analytics, GA4, Adobe Analytics, Mixpanel and more
- Google Tag Manager, Tealium and Adobe tag management
- Meta Pixel, TikTok Pixel, LinkedIn Insight and Pinterest
- HubSpot, Klaviyo, Marketo, ActiveCampaign, Braze and more

- Cloudflare, CloudFront, Fastly, Akamai and Bunny CDN

How website detection works
How does WebBuildFinder detect website technologies?
A single clue is rarely enough. The scanner combines several public signals before it reports a technology, then shows the evidence and confidence behind the result.
Fetch the public response
Validate the URL, resolve a public IP, follow redirects and collect the final HTML and response headers.
Inspect page fingerprints
Check markup, generator metadata, script/style URLs, cookies and selected first-party asset content.
Match technology evidence
Run those signals against the technology registry and attach confidence, version clues and evidence.
Run platform-specific checks
When Shopify or WordPress is confirmed, automatically add themes, apps, plugins and platform metadata.
Technology coverage
What technologies can WebBuildFinder detect?
The detector covers hundreds of public fingerprints across CMS, ecommerce, frontend, backend, analytics, infrastructure, payments, security and other web-technology categories. Coverage continues to expand as new reliable fingerprints are added.

Website technology detector FAQ
Questions about finding what a website is built with.
How do I find out what a website is built with?
Enter the public website URL into WebBuildFinder and run a scan. The tool checks publicly visible signals such as HTML, response headers, scripts, stylesheets, cookies, metadata and selected platform endpoints, then groups the technologies it can verify into a readable tech stack report.
What can a website technology detector identify?
Depending on the signals a site exposes, a technology checker can identify CMS and ecommerce platforms, themes, apps, plugins, JavaScript and CSS frameworks, backend clues, programming languages, analytics, tag managers, CDN and hosting services, payments, authentication, security tools and other integrations.
Can WebBuildFinder detect Shopify and WordPress?
Yes. When Shopify is detected, WebBuildFinder can look for public theme metadata and visible storefront apps. When WordPress is detected, it can look for the active theme, child or parent theme clues, visible plugin paths, asset versions and public REST namespaces.
Can it detect React, Next.js, Vue, Nuxt or Tailwind CSS?
Yes when those technologies expose reliable public fingerprints. The same applies to many other frontend frameworks, UI libraries and build tools. Production bundling and deliberate fingerprint removal can make some technologies harder to identify.
Can a tech stack checker detect backend frameworks and programming languages?
Sometimes. Server-side technologies are harder to detect because they can be completely hidden behind a CDN or reverse proxy. WebBuildFinder reports backend and language clues only when public evidence supports them, rather than treating a weak hint as proof.
Why do different website technology checkers show different results?
Detection tools use different fingerprint libraries, confidence rules and crawling methods. A site can also load technologies conditionally or hide them behind a firewall. For that reason, WebBuildFinder shows public evidence and confidence instead of claiming that every technology can always be identified.
Is WebBuildFinder free to use?
Yes. The public website technology checker can be used without creating an account. Enter a URL, run the scan and review the technologies that can be identified from public signals.
