If you've maintained a website for any length of time, you'll know that links very quickly become broken, because we move, delete or change our own pages, and other people that we link to do the same.

A broken link on your site is a dead end for your visitors and will also be bad news for your search engine optimisation (SEO).


Integrity is a link checker, no more, no less, no frills - and free (donationware). If you'd like:

PC Version?

If you're of the Windows persuasion, use Xenu's Link Sleuth. The developer has made it clear that he's not interested in producing a specific Mac version. I don't do Windows so there won't be an Integrity for Windows. I've no connection with Tilman Hausherr (though he seems like a great guy), and this is no more than a personal recommendation to use the Link Sleuth if you're a pc user.

Version History

v4.5.3 Released January 2014

v4.5.2 Released December 2013

v4.5 Released October 2013

v4.4.1 Released September 2013

v4.2.2 Released June 13

Fixes problem with new link text column in By page view not always displaying accurate data where same link occurs multiple times on same page
Tweaks how information is displayed in new expandable By link view

v4.2.1 Released June 13

Fixes crash on launch for some existing users

v4.2 Released June 13

improvements to interface:
- Changes the 'by link' view to an expandable view, occurrences can be seen by expanding view rather than as previously having to open the link inspector
- Link inspector still appears on double-click from link views and is improved
- Adds context menus to the 'by link' and 'by page' views and the 'appears on' table in the link inspector - a number of actions can be performed with a right-click (or control-click) including 'Copy URL' and where appropriate Visit, Highlight and Locate
- The new Copy URL action is available with a command-C and will copy the URL of the selected item
- A new Locate action lists how to click through from the starting url to find the link in question. It is available via context menus, the link inspector and cmd-shift-L
- Adds 'link text' column to 'by page' view
- Change to wording: 'on page' now 'appears on'
- Changes default for highlighting a link on the page - now looks like highlighter pen rather than a box around it (changes prefs defaults to 'background' rather than 'border', and changes the default colour to yellow rather than dark grey - ie (existing users can select this option in prefs if they like))

Ignores and continues if 'bad SSL certificate' warning is encountered. But only for the website being tested. (anything else, ie external links, won't be followed anyway)
If image checking is switched on, now collects alt text and displays in 'link text' columns
Some options removed from Preferences>Views>By Link view (Status, URL, On Page) because these are needed for the new outline view to work properly
Exporting from 'by link' view better than previously. (was putting all 'on page' information in a single cell to reflect the view - led to problems due to Excel's 256-character limit)
Export added to by Page view
Exports from expandable views reflect the state of the view, ie which rows are expanded or not

v4.1.1 Released April 13

Adds 'bad links only' checkbox (was possible to toggle bad links / all links using menu or toolbar button. This new checkbox makes the option more obvious if toolbar not showing and for similarity to Scrutiny)
Adds filter drop-down list (All, Internal, External, Images) and search box above all views
If flagging blacklisted urls, then the highlight colour used is orange or the warning colour (was red or bad link colour). Not an error so inappropriate to use an error colour.

v4.0.4 Released February 13

Fixes problems creating black/whitelist rules on first run with no settings saved
Correctly sets window to edited (dirty spot in red button) when black/whitelist rules are changed, triggering prompt to save when switching settings

Version 4.0.3

Small fixes, full release February 2013

Version 4

released as Release Candidate January 2013

Major improvements to the data storage and engine meaning that even small sites will crawl more quickly and large sites will crawl very much more quickly without slowing down or losing responsiveness
When stop button is pressed, all open threads are abandoned, and then recreated if 'continue' is pressed. Gives a much better user experience
Routines for 'by page' view re-written to avoid apparent hanging at the end of the crawl of a big site
Adds new settings to Preferences, allows setting of some limits - default to 200,000 links. Offering the option of limiting the crawl of a large site (maybe better achieved by using blacklist / whitelist rules) but also a safety valve to prevent crashing due to running out of resources when crawling very large sites
If starting crawl within a directory, crawl is limited to that directory, ie crawl will go down a directory structure but not up. This matches users' expectations. Previously, crawl extended to all pages in the same domain
Blacklist and whitelist boxes replaced by a more user-friendly table of rules (existing data will be presented in the new way)
Moves 'check links on custom error pages' to settings rather than global preferences
Increases maximum number of threads from 30 to 40 (will improve crawling for some sites) with the default now 12 rather than 7. Extreme left (labelled 'fewer') is still a single thread.
