The ones hosted by the W3C? Could you consider hosting your own copies (The
W3C provide source code) since it sounds like your tool is going to hammer
them with lots of requests, and they have had performance issues due to too
many people using their (free) service at once in the past.
David, allow me to complete your post (with which I fully agree) with
additional info.
Online validator services:
--------------------------
WDG HTML Validator
http://www.htmlhelp.com/tools/validator/
Validome validation services:
http://www.validome.org/
Validome validator has multi-lingual support (English, Français, *усская
версия and Deutch) and its report is more complete, more accurate as it
is able to report more errors
http://www.validome.org/lang/en/errors/ALL
Validateur HTML du W3Québec en Français
http://www.w3qc.org/validateur/
Multi-validation Site valet for intermediate and advanced users
http://valet.webthing.com/
Free offline extension:
-----------------------
HTML validator as a Firefox extension working offline (SGML parser):
Marc Gueury's Firefox extension (currently at version 0.8.3.9, still in
beta) when using the SGML parser will report the same errors as the W3C
markup validator. It even has examples, explanations of errors, examples
on how to correct them, etc.. This is the future of HTML validators: no
files to upload, no extra application to install
https://addons.mozilla.org/en-US/firefox/addon/249
or
http://users.skynet.be/mgueury/mozilla/index.html
Opera 9 has a feature (Error console) to report HTML errors without
submiting the webpage online. It does not work right now but one can
expect future Opera 9.30 or Opera 10.x versions to implement this feature.
Shareware offline HTML validator:
---------------------------------
"A real validator" from WDG is an HTML validator for Windows; the
registration cost for this shareware is $25. US. It can validate several
HTML documents at once and it comes with a complete HTML 4.01 reference.
Such reference is quite handy as it provides examples, explanations and
useful information: an user can make his webpage markup code valid and
learn HTML at the same time.
