Looking for HTML validator for Mac

Are there any HTML validators for Mac, HTML 5 preferably, thats out there and relatively popular in the industry?
I used to use HTML Tidy for firefox, but its outdated I guess.
Hopefully its a chrome extension.
Of course, preferably its free to :rofl:

Why not just use the W3C validator http://validator.w3.org/

Also http://www.456bereastreet.com/archive/201102/html5_validator_extension_updates/ (you should only use this with a local copy of the validator; making it use the online validator.nu service will make you DOS the service).

HTML (all versions) is not , nor should it be, plaform specific. As mentioned above , I tend to use W3C validaror , as it allows direct input or links. Some text editors offer validation features, off the top of my head CODA comes to mind.

HTML validator for Mac is available. Btw, what kind of Mac version do you used? If you Mac is OS X version, you can use this HTML with simple, reliable and repeatable. And it works without connecting to the internet.
