Xenu's Link Sleuth

"Xenu's Link Sleuth keeps me honest"
This is an exceptional tool for web page integrity. I use it primarily for creating web pages for non-profit organizations so the price can't be beat. When I moved to a new operating system or computer, the author worked with me to repair some bugs.
I can't think of anything I do not like. Too many broken links come frmo my limited testing environment and not the product.
My web pages have far fewer problems since I run Xenu's Link Sleuth on every page I create.
