Please recommend a tool that checks for broken links on a web site.

not required, but would be nice to have:

  • checks standards-compliance of the HTML, CSS, Javascript, ...
  • displays permanent redirects

  • That's a great tool! I find it very useful to validate the links in my project. Thanks to both!

  • Why add a note about Lenny? Here, we are trying to keep things generic, if we can help it.

    @Tshepang: Because I'm trying to be useful. Does it bother anyone? Stop being pedantic, please. Commented Jan 18, 2011 at 14:04

    @Tshepang: I disagree. I think it's a useful note that doesn't take away from anyone else - the source is still in the first link. Having said that, if a moderator asks me to remove it I will do so. Commented Jan 18, 2011 at 15:40

    Note that wummel stopped development of LinkChecker in 2016. Active development continues in the linkchecker/linkchecker repo. Unfortunately, Google still (as of late 2020) returns the old wummel repo as the first hit if you search for LinkChecker. Commented Sep 29, 2020 at 10:14
