BLT 1.0.3 - Popular Pick

BLT (Braxton's Link Tester) is a Shareware link checker for Mac OS X.
Easy to Use - Use BLT just as you would a web browser. Type in your address, or use a file browser, and sit back and watch. Quickly filter the results by status or by text. Results can be viewed either "flat" or as a "tree."
Document Based - Create BLT Documents that remember the settings and results from previous checks. Control the default document settings in the Preferences.
Export - Create HTML, CSV/Text, or OmniGraffle files from the results. Exporting is done through loadable bundles, so you can write your own exporters to expand BLT.
OS X Friendly - Uses the same URL caching mechanism as Safari, uses the Keychain for authenticated sites, results filtering by search field, etc.
