Where does this link really go?

See every step a link takes and where it finally lands. Find long redirect chains, temporary redirects that should be permanent, and links that end on an error.

Free, with no account needed.

What it checks

What you get from the redirect checker

  • Every step

    Each address and status code along the way.

  • Long chains

    Three or more redirects slow pages down, and search engines may give up.

  • Dead ends

    Links that redirect their way to an error page.

For developers

Three lines from your own code

Every tool is also an API, with one simple answer format. Keep your key on your server.

JavaScript

const res = await fetch("https://www.purlock.com/v1/tools/redirect-checker?target=http%3A%2F%2Fexample.com", {
  headers: { authorization: `Bearer ${process.env.PURLOCK_API_KEY}` },
});
const report = await res.json();

Prompt for Cursor or Lovable

Add a call to the Purlock Redirect checker API on the server side of this app. Send GET https://www.purlock.com/v1/tools/redirect-checker?target=VALUE with the header "Authorization: Bearer" and the PURLOCK_API_KEY environment variable. The JSON answer has status ("good", "attention" or "bad"), headline, checks (each with level, title, detail, fix) and data. If the call fails or times out after 3 seconds, carry on as if it wasn't there. Never put the API key in client code.

Free plan: 100 calls a month. Individual: 5,000. Business: 25,000.

FAQ

Questions, answered

What's the difference between a 301 and a 302?
A 301 says a page moved for good, so search engines move its ranking to the new address. A 302 says the move is temporary.
How many redirects does it follow?
Up to 5, the same limit as the rest of Purlock.
