HTTP headers checker
Check HTTP response headers for a website
Paste a domain to inspect visible server, powered-by, security, caching, CDN, and generator header signals.
Try:
What this checks
- Server and powered-by headers when exposed
- Detected CDN, platform, cache, and security headers
- Stack context so raw headers are easier to interpret
How I treat the evidence
Headers are public, but they are often partial. Many sites remove server names or put a CDN in front.
That is why the result pairs headers with DNS, SSL, hosting, and technology fingerprints.
Why do server headers sometimes look generic?
A CDN or reverse proxy may answer before the origin server. The header is still useful, but it may describe the edge, not the app.
Is this a security scanner?
No. It reports visible headers and context. It is not a vulnerability scan.
