Link checking

Links on a web page very quickly become broken (link rot) because we move, delete or change our own pages, and other people that we link to do the same. Using a link checker regularly will improve your website's user experience (UX) and search engine optimisation (SEO).

Integrity is the free link checker for Mac. It's OSX native, very fast and accurate.

Integrity is a free link checker. More features and options such as exporting your data, authentication (logging in), managing multiple sites, sitemap generation, SEO checks, spelling & grammar are all available in two related apps; Integrity Plus and Scrutiny. Here is a comparison of major features


Integrity is donationware, which means that it's available to personal users free of charge with no restrictions. I'm very grateful for donations and if you choose to donate, it will encourage further development of this and other OSX software.

If you are using Integrity as part of your business, please buy a licence for the more powerful Integrity Plus, or Scrutiny. End user licence agreement
