Privacy and security
- The URL is sent to our API only to fetch the headers; it is never persisted or logged.
- Private, loopback, link-local, and other reserved IP ranges are blocked for the target and every redirect hop — see the FAQ.
- The response body is never read, stored, or returned.
- Requests are not included in analytics or error reporting.
Limitations
- Only
httpandhttpsURLs are accepted. - Up to 5 redirects are followed; further redirects return an error.
- Each request has a 5-second timeout.
FAQ
Does this tool follow redirects?
Yes, up to 5 hops. Every hop is independently validated before being followed, and the full redirect chain is shown in the result.
Can this tool reach my internal network or cloud metadata endpoint?
No. Private, loopback, link-local (including the 169.254.169.254 cloud metadata address), and other reserved IP ranges are blocked, for both the target you enter and every redirect hop.
Does it show the response body?
No — only the status code and headers. The body is never read or returned.
