Enter the web address of a website above. We will validate the site's HTML, check if it exists in the directory, and allow you to optionally submit it if it does not.

valid8or uses the same validation engine as the W3C HTML validator, and supports both HTML and XHTML documents.

Submitting your site to the valid8or directory of valid HTML is completely free, and we aim to approve submissions within 24 hours or less when circumstances permit.
