About Broken Link Checker
Crawl a URL and report 404s, 5xx, redirects, slow links. It sits in the web & network shelf alongside 64 other web & network tools, needs no account, and keeps the same behaviour whether you open it here or call it through the REST API.
It works from what you type in rather than a file and gives back JSON. The work happens on our servers. There is nothing to upload, and any file it makes is deleted an hour later — 24 hours if you are signed in. The same operation is available programmatically at POST /v1/web/broken-link-checker.
Broken Link Checker questions
Where does Broken Link Checker do its work?
On our own servers. There is no file to upload: what you enter is sent over TLS and processed on our infrastructure — no third-party processing APIs are in the path — and any file it makes is deleted within an hour.
Do I need an account to use Broken Link Checker?
No. Broken Link Checker works without signing in, and that is not a trial — it is how the free tier works. An account only matters for things that need one to exist at all: larger server jobs against your quota, API keys, saved workflows and billing.
Can I run Broken Link Checker from my own code?
Yes. Every tool on the site is reachable from the REST API with the same slug — `broken-link-checker` — and the same options as this page, so anything you can do here you can automate.
