Alternatives to SEOmoz's Crawl Diagnistics

[BestOdds]

I really like SEOmoz's Crawl diagnostics reports, it goes through the pages and finds all sorts of valuable information, I wanted to know if there are any other services that compete against this specific service, to test the accuracy of their crawl diagnistics.

Thanks

I like Screaming Frog

Xenu's Link Sleuth is very helpful in finding link issues

I agree with Irving as well. Dr. Pete wrote a great comparison of the two: http://www.seomoz.org/blog/crawler-faceoff-xenu-vs-screaming-frog

In brief, Xenu is free. It is old but it works. If you were around before Windows and don't mind using older tech, then Xenu is great.

Screaming Frog costs about $99 Euros but it is much more user friendly. They have an excellent support staff as well. I use the tool almost daily.

Google Webmaster Tools is handy to use in conjunction with the other tools listed.

Also, SEO Powersuite's SEO Spyglass tool is pretty decent.
