Website Technology Detector
Identify the likely tech stack from public signatures
Detected signatures
No known technology signatures were detected — the stack may be custom or well-hidden.
How it works: we fetch the site's homepage and match public signatures (headers, meta tags, asset paths). Results are best-effort estimates, not guarantees.
Website Technology Detector — Complete Guide & Instructions
MakeCard Website Technology Detector fetches a site's public homepage and matches known signatures — response headers, generator meta tags, script and asset paths — to identify the CMS, frameworks, and libraries it likely runs on. Results appear as labeled badges with the HTTP status, giving a quick best-effort read on any site's stack. Useful for developers, agencies, and curious visitors researching how a site was built.
How to Use Website Technology Detector
- 1 Enter a website URL such as example.com in the Website URL field.
- 2 Click "Detect Technologies" — the tool fetches the homepage and scans its signatures.
- 3 Read the detected technology badges plus the HTTP status of the response.
- 4 If nothing is detected, the site is likely custom-built or hides its signatures.
Key Features & Capabilities
- Signature matching across headers, meta generator tags, and asset paths.
- Identifies common CMSs, frameworks, libraries, and server hints.
- HTTP status shown alongside the fetched URL.
- Clear verdict when no known signatures are found.
- Accepts bare domains — the scheme is added automatically.
- Fast single-request scan of the public homepage.
Supported Formats & Specifications
| Parameter | Specification |
|---|---|
| Input | Domain or full URL |
| Signals | HTTP headers, meta tags, script/asset paths on the homepage |
| Output | Response status + list of detected technology names |
| Method | Server-side homepage fetch then signature matching |
| Accuracy | Best-effort estimate — hidden or custom stacks may show nothing |
Practical Everyday Use Cases
- Checking whether a competitor's site runs WordPress, Shopify, or a custom stack.
- Qualifying leads before pitching redesign or migration work.
- Verifying that headers and meta do not leak your own stack.
- Researching which library a site uses for its UI.
- Confirming a client's claimed platform before a project.
Pro Tips for Best Results
- Absence of signatures does not mean absence of technology — many stacks deliberately hide themselves.
- Results reflect the homepage only; inner pages may use different systems.
- Cross-check with the robots.txt or sitemap for platform hints like /wp-content paths.
- Use it for research, not security probing — fingerprinting is a starting point, not proof.
Common Problems & Solutions
The site may block automated requests or be unreachable — verify the URL loads in a browser first.
The stack is likely custom or its signatures are stripped — many production sites remove meta generators and version headers.
Detection is signature-based; sites can spoof or proxy headers, so treat results as an estimate.
Privacy & Security
100% Client-Side Execution
The URL you enter is fetched server-side to read its public homepage signatures — the only way to inspect headers and markup. We do not log or store the sites you scan.
Frequently Asked Questions
Everything you need to know about using Website Technology Detector
Enter its URL in this detector — it reads public signatures in the headers, meta tags, and asset paths and lists matched CMSs, frameworks, and libraries as badges.
Yes — common platforms leave recognizable signatures like /wp-content paths, generator meta tags, or CDN hostnames, which the matcher identifies.
Custom-built or hardened stacks strip their signatures. No result means nothing matched — not that the site uses no technology.
It is a best-effort fingerprint — reliable for sites with visible signatures, less so for proxied, custom, or deliberately hidden stacks.
