HTTP status code checker

What does that URL actually answer — and where does it send you? Paste it in.

Public http:// and https:// URLs, GET only.

What the codes mean

2xx — it worked: 200 OK is the answer you want. 204 means "done, nothing to send back".
3xx — it moved: 301 is permanent, 302/307 temporary. We follow up to five hops and show you where you land.
4xx — you asked wrongly: 401 needs credentials, 403 refuses them, 404 has nothing there, 429 means you are being rate limited.
5xx — it broke: 500 is a crash, 502/504 mean a proxy could not reach the thing behind it, 503 means it is unavailable on purpose.
No code at all: DNS failure, refused connection, TLS error or timeout — the request never got an answer. Those are the failures that matter most, and the ones a browser hides from you.

API response time test — three samples, min/avg/max.

Free uptime monitoring — check it every 5 minutes instead of once.
