Tech Stack Detector

Detect the technologies powering any website CMS, frameworks, analytics, CDN, and server software.

Server-assisted public lookup

Nothing detected. The site may be blocking requests or using uncommon technologies.

Detected Technologies

Detection is based on HTTP headers and HTML patterns results may not be exhaustive.

What is the Tech Stack Detector?

The Tech Stack Detector examines the HTTP response headers, HTML meta tags, and script signatures from any URL to identify the technologies powering the website. It can detect the CMS, JavaScript frameworks, analytics tools, CDN providers, server software, and more, grouping the results by category so they are easy to scan at a glance.

This is useful for competitive research, technical due diligence, or simply satisfying your curiosity about how a site is built. It is also a good quick check when you want to know whether a client site is running a version of WordPress, which CDN they are on, or what analytics platform they use.

How to use the Tech Stack Detector

Enter a full URL in the input field, for example https://example.com, or just the domain name and the tool will add https:// automatically. Click Detect. The tool fetches the page headers and HTML from our server and analyzes them against a set of known technology signatures. Results are shown grouped by category, such as CMS, JS Framework, Analytics, CDN, and Server. You can also expand the Raw Headers section to see all the response headers the server returned.

Frequently asked questions

Detection accuracy depends on how much information the site exposes. Many technologies leave identifiable markers in headers, meta tags, or script paths. However, sites that actively obscure their stack, remove version numbers, or serve minified bundles with no identifying paths will return fewer results. Think of it as a best-effort scan rather than a definitive audit.
Yes. Developers can remove the X-Powered-By header, rename generator meta tags, hash asset filenames, and configure the server not to reveal version information. Some security-conscious sites do this to reduce the attack surface. If a site returns no results, it may be actively suppressing that information.
WordPress is by far the most widely used CMS on the internet, powering a large percentage of all websites. It is also one of the easiest to detect because it typically exposes wp-content paths in its HTML. Shopify, Wix, and Squarespace are also commonly detected on e-commerce and small business sites.
Browser extensions like Wappalyzer run inside your browser and can inspect JavaScript variables, cookies, and dynamically loaded content after the page renders. This tool runs server-side and only sees the initial HTTP response, so it may miss technologies that are only visible after JavaScript executes. Extensions tend to be more comprehensive but require you to install them.
No. This tool fetches the raw HTTP response and does not execute JavaScript. Technologies that only reveal themselves through client-side rendering, such as certain single-page application frameworks that inject meta tags after load, may not be detected. The raw headers and initial HTML are analyzed, which covers most server-side and CDN technologies reliably.

What is the Tech Stack Detector?

The Tech Stack Detector analyzes a website's public-facing signals - HTTP response headers, HTML meta tags, JavaScript globals, script filenames, and CSS class patterns - to identify the technologies powering it. In seconds, it can reveal the CMS, web framework, JavaScript libraries, analytics platforms, CDN, web server, and more. This is useful for competitive research, developer curiosity, and technology due diligence.

How to use the Tech Stack Detector

  1. Enter the full URL of the website you want to analyze (e.g., https://example.com).
  2. Click Detect to run the analysis.
  3. Browse the categorized results: CMS, Framework, JavaScript Libraries, Analytics, Hosting/CDN, Email tools, and more.
  4. Click any detected technology to see which signals were used to identify it.
  5. Export the results as JSON for use in reports or further research.

Frequently asked questions

Detection accuracy depends on how much information a site exposes publicly. Sites that remove generator meta tags, obfuscate script names, and use custom CDNs will reveal less. Detection is highly accurate for standard CMS installs (WordPress, Shopify, etc.) and common libraries.
Partially. You can remove or spoof headers, strip version numbers, and rename files, but JavaScript behavior and certain HTML patterns are harder to conceal. Security through obscurity is not a substitute for proper security practices.
Yes. This tool only analyzes publicly visible information returned by normal HTTP requests - the same data any browser receives when visiting the site. It does not probe, exploit, or access any non-public resources.
