HTTP Status Code Reference & Tester

Search HTTP status codes, read meanings, and test a URL's response code.
Selected Code
URL Tester
Note: CORS may block browser fetches. Use a server-side proxy for unrestricted testing.
Quick reference
  • 2xx — success
  • 3xx — redirect / further action
  • 4xx — client errors (bad request / unauthorized / not found)
  • 5xx — server errors
Tip: Click any code row to copy its details to the right. If a fetch is blocked by CORS, you can test via a server-side endpoint (I can provide a small Django view that proxies requests if you want).
