What is HTTPSense?
HTTPSense is a free suite of URL analysis and HTTP debugging tools built for developers, DevOps engineers, and SEO specialists. Enter any URL and get instant, detailed insights into how it behaves on the web — from redirect chains and response headers to SSL certificates and DNS records.
Every tool runs real HTTP requests against live servers and returns structured, actionable results. No signup required, no rate limits for normal use, and no data is shared with third parties.
Why Use HTTPSense?
- •All-in-one platform — Redirect tracing, header inspection, SSL analysis, DNS lookups, and meta tag auditing in one place. No need to switch between multiple tools.
- •Real HTTP requests — Every inspection makes actual requests to production servers, giving you the same results a browser would see. No simulations or cached data.
- •Security-focused — Header Inspector grades your security header posture with value-based analysis. SSL Inspector checks certificate validity, protocol support, and cipher suites.
- •Developer-friendly — Raw JSON output on every tool for easy integration into scripts and CI/CD pipelines. Deep-link to any inspection via URL parameters.
