Free Broken Link Checker for Any Web Page
Enter a page URL and we'll check every link on it — up to 100 — and list the ones that are broken.

How it works
We load the page
We fetch the page from our servers and collect every link (<a href>) on it, resolving relative links.
We check each link
Each link is requested in parallel. Anything returning a 4xx or 5xx status, or not responding, is flagged as broken.
You fix what's broken
Broken links are listed first with their status code or error, so you know exactly what to update.
Frequently asked questions
Why do broken links matter?
They frustrate visitors, waste search engine crawl budget, and make a site look neglected. On key pages — docs, pricing, sign-up — they can cost you customers.
Does it check my whole site?
This free tool checks the links on one page (up to 100). Site Monitor's paid plans can check linked pages for downtime on an ongoing basis.
Why is a working link reported as broken?
Some sites block automated requests or require a login, and return 403 or 401 to tools like this one. If a link works in your browser, it's likely one of those.
Which links are skipped?
mailto:, tel:, and javascript: links, in-page #anchors, duplicates, and links to private network addresses.
