Good link checking tool?

Can anyone recommend a good, free link checker to check all pages within a domain? Ideally a browser add-on or a web app (otherwise something that runs on OSX).

Crucially it needs to follow links recursively within a domain. Links outside the domain should be followed to a depth of 1, but not checked recursivel开发者_StackOverflow社区y.

This is for the fairly common situation where you want to check all pages on your own site, but not evaluate the links on e.g. Google's homepage.

I can't find anything suitable. Am I missing something?

I've tried the Firefox LinkChecker add-on and the W3C link validator - neither seem to have the 'follow recursively within a domain' property, or am I being dumb?

I know Xenu does this, but I don't run Windows.

The W3C offering does only check to a depth of 1 when it leaves the domain.
