Does almost the same stuff, it's free and it's browser based 
Beware that ScreamingFrog doesn't understand javascript links so if you have done some JS trickery, your site may not be crawled fully. Google and other spiders know their way around your basic javascript links so this is just a limitation of your average crawler.
Doing a spider yourself that executes JS isn't that hard but in most cases ScreamingFrog is perfectly adequate 
great sitemap find.... shit... i'm finding like 53 links in the sitemap that are showing errors..... dont think thats why i got penguin slapped... but still...
