: Broken URL Finder? Is there a broken-URL finder application that I could use to scan a website for broken links? (A Mac application would be better.)

@Lengel546

The W3C Link Checker is one of the oldest online services that checks for broken links.

You could also try A1 Website Analyzer (Windows tool, but can run in VMWare/Fusion under Mac) It can tell you of all URL references site-wide (e.g. which pages link to a 404 URL + usually also line numbers), HTML/CSS errors etc.

Google Webmaster tools will report on broken links. It's a simple tool, free to install to a website.....and platform agnostic. If you're not already using it, it can help you boost your SEO and useability as well.

For Windows users: Xenu

For *nix/Mac: wget (usually installed by default)



Update: Typical wget usage:

wget -r --spider -b -o /var/tmp/wget.log target.site.com/

-r - Recursive download
--spider - Check downloaded content for new links, then discard
-b - Run in the background
-o /var/tmp/wget.log - Target log file target.site.com/ - Replace with the site you want to check


wget will create a log file detailing the status codes reported while downloading content from the target site - note that this method will catch links to nonexistent content from within the domain, however, off-site links will not be checked (which is why it pays to monitor your site's error logs).
