HTTP Header Checker

Speed and privacy sit at the core of HTTP Header Checker. With all response headers and security analysis, the tool delivers results in seconds while keeping your data entirely on your device. No cloud uploads, no server-side processing, no third-party tracking.

HTTP Header Checker was built for people who need dependable results without jumping through hoops. Visual score bar showing what percentage of security headers are properly configured. That kind of straightforward design is what sets this apart from the many other tools that promise the same thing.

Start by enter url. Enter the URL you want to check response headers for. HTTP Header Checker accepts input immediately. No loading screens or configuration dialogs stand between you and your result.

Once your input is ready, choose method. Select HEAD (faster) or GET (full response) method. Results appear in real time, giving you immediate feedback before you commit to a final output.

Finally, review results. See headers by category and review the security header analysis. The entire process from start to finish typically takes under a minute for most inputs.

For the best experience, keep these points in mind: A security score of 70%+ is good. Key headers to have are HSTS, CSP, and X-Content-Type-Options. HEAD requests are faster because the server doesn't send the response body, just headers. Small adjustments like these can make a noticeable difference in your output quality.
