Website technology checker
Knowing which technologies power a website helps you know what to keep updated. This checker identifies common platforms from public page content and headers and flags when your server announces exact version numbers, which helps attackers target known flaws.
What this checks
- CMS and platform indicators (WordPress, Shopify, Wix, Squarespace, Webflow)
- Front-end frameworks (Next.js, React, Vue, Angular)
- Server and CDN (Nginx, Apache, Cloudflare, Vercel, PHP)
- Version disclosure in Server / X-Powered-By headers
How to use it
- Enter your domain.
- Check the detected list matches what you expect.
- Remove version strings from headers and keep detected platforms and plugins updated.
Methodology and limitations
Detection is pattern-based and can miss or misidentify technologies. PixelPrivate performs passive checks against publicly visible configuration only. It does not test for exploitable vulnerabilities, so a clean result is not a guarantee of security. Read the full security methodology.
Key terms
- Security headers — Security headers are HTTP response headers that switch on browser protections, such as forcing HTTPS, restricting script sources, or stopping your pages being framed by other sites..
Frequently asked questions
Is it bad that my technology is detectable?
No. Almost every site is fingerprintable. What matters is that the software is patched.
