"There aren't many freeware programs out there these days that are this well done and useful."
- Tim Matheson, CSE HTML Validator User

"I downloaded CSE HTML Validator Lite about two months ago and have used it ever since. It's absolutely delightful to use - and has options for everything you can think of (and a lot that you can't!). But in spite of the options, it can be used by amateurs like myself with the default values only. I have tried several other validators before and none comes near it for ease of use, flexibility, and thorough reliability.

- Phil Taylor, CSE HTML Validator User
