Check a URL's redirects
Type an address. We follow its redirects from our server and show every hop with its status code, then flag loops, chains of more than two redirects and any hop on plain http. Free, no account.
How the trace works
- The address is parsed first: http and https only, ports 80 and 443 only, no usernames, no IP addresses and no internal names such as localhost. Anything else is refused before any request.
- The name is resolved and every address it points to must be public. Private, loopback, link-local (cloud metadata included), multicast and reserved addresses are refused, and the connection goes to the address that was checked.
- We request the address and follow each redirect by hand, up to 4, and every hop is checked the same way before it is requested. With no http:// or https:// in front, we start on http so you can see whether it moves to https.
- Only the start of each page is read (4 KB at most); the page itself is not kept. The whole trace has a 10-second budget.
What gets flagged
- Loop: the same address comes round again. Browsers stop with "too many redirects".
- More than 2 redirects: for example http to https, then to www, then to a trailing slash. Each is another request before the page starts.
- Plain http on the way: a hop from https back to http, or a chain that ends on http.
- Temporary redirects (302, 303, 307) used for what looks like a permanent move such as http to https or adding www.
The status codes: 301 and 308 say a move is permanent; 302 and 307 say it is temporary; 303 sends the visitor to another page after a form.
Using it before a pitch
A redirect loop or a site that does not move visitors to https is something you can show the owner in one screenshot. To find businesses to check, search 67Leads by trade and city, then run their sites through the bulk URL checker.

Questions
Type it above. Every hop is listed with its status code, in order, ending on the final address.
One is normal, for example http to https. Two is common. More than two means visitors wait for extra requests, and the chain can usually be cut to one.
A 301 (or 308) says the move is permanent. A 302 (or 307) says it is temporary. For http to https and www changes, a permanent redirect is the usual choice.
So the first hop shows whether the site moves visitors to https. Type the full address with https:// to start there instead.
No. It fills templates with what you type and makes no network calls.
No. The result is written when the page is served and not saved.
