HTMLValidator is a tool that allows you to verify that your webpages meet W3C html and xhtml standards.

HTMLValidator works offline without access to the Web and because HTMLValidator uses the same validation technique as the official validator you can be assured the the pages you create work correctly.

This is a great validator. It uses the service from http://validator.w3.org, but is is not a simple wrapper, it is a local version. So it can test also local files (which the online checker does not allow) and is so much faster than the web validator which sometimes is very un-responsive and slow.

The best thing: It can scan complete local side with a bunch of files as batch processing in no time and we use it as quality check before we go online with something. That is very time-saving and less easy to overlook something.

It has it's limits, though: It does not test CSS. And i guess the engine does not understand HTML5 code at all.
The software is outdated in a way.

And the developer does not seem to be active on this project. No update in a long time and the developer does NOT respond to emails at all; I tried twice.

Very sad. I hope this software will be further maintained, I have not found other software yet that came any close to this set of time-saving features and I would love to keep this in my set of testing tools as long as possible.

isn't the included validation engine 0.8.3 is from 2008 and totally outdated? And it can't do batch processing, right?

It looks like this is a wrapper for http://validator.w3.org/

Somehow development has been slow for this program, which was last commented on about 4 years ago. Asking money now for a final version that has been deprecated for over 4 years is a bit harsh.

Well, I do not know whose fault this is, but I am always annoyed if a beta version is announced as "free" on this website and then we discover that the final version costs (in this case a substantial amount of) money. If I would have known that HTMLValidator would cost more than five bucks, I wouldn't have downloaded it in the first place. I guess I have to delete all prefs and caches and redownload XMLNanny, which is not as good as this software, but actually free and remaining so. (The last point is particularly important because the beta versions of HTMLValidator had expiration dates, so they were only free/usuable for a limited amount of time. I think we should be informed about this as early as possible.)

This is great. Up until I discovered this, I used the Firefox web developer plug in, but I don't use Firefox as my regular browser, so this is a great find for me. Works well, and I love the list creation - great for keeping on top of changes in an entire development site, and the batch validate is a killer feature.

Feature request/suggestion - can we have it so it validates CSS too - that would be waaaaaaaay cool!

Congratulations and big thanks to the developer for a tool I'll be using daily.

Nice little tool. Version b1's warning dialog box still references SQLValidator though. Might want to clean that up.
