Why we built this
Broken links are one of the most common and most fixable problems on the web. They hurt SEO rankings, frustrate visitors, and quietly erode trust in a site — but most site owners don't realise how many they have until someone complains. Paid tools to catch them are expensive, and free ones often cap crawls at a handful of pages or block external link checking altogether.
We built Broken Link Finder to scratch our own itch: a tool that will crawl a site, follow its internal links, check every external link it finds, and give a clean report of what's broken — all without a signup, an upsell, or a crawl limit that only covers the homepage. It uses real HTTP requests, not just status code lookups, so it catches soft 404s and redirect loops that other tools miss.
Who's behind it
Broken Link Finder is part of ModusOp, a platform for operations, bookings, and client management built for small businesses and agencies. We build free developer tools like this one because we use them ourselves when auditing client sites, and because they're a good way to give back to the web development community.
The tool is built and maintained by JWWD, an Australian web development studio that handles the technical side of ModusOp. We've been shipping web software since the early 2000s and we believe that the tools developers use every day should be fast, useful, and free wherever possible.
