HTTP Status Checker
Check the HTTP status code of any URL — verify if sites are online, check redirects, and detect errors.
About HTTP Status Checker
HTTP status codes are three-digit numbers returned by web servers to indicate the result of an HTTP request. The first digit indicates the response class: 1xx (informational), 2xx (success), 3xx (redirection), 4xx (client error), 5xx (server error). Checking HTTP status codes is essential for monitoring website uptime, verifying redirects are configured correctly, debugging broken links, and confirming APIs return the expected status for different operations.
FAQ
What is the difference between 301 and 302 redirects?
301 Moved Permanently tells browsers and search engines to permanently update their records — search engines transfer link equity (PageRank) to the new URL, and browsers cache the redirect. 302 Found is a temporary redirect — search engines keep the original URL indexed, and browsers don't cache it. Use 301 for permanent moves, 302 for temporary redirects (A/B tests, maintenance pages).
