HTML Checking for Large Sites

Rocket Validator automatically checks your pages on the W3C Validator.

Duplicate attribute “X”.

Attributes in HTML elements must be unique. For example, <a id="one" id="two"> is invalid as the attribute id is repeated.

50,000 Accessibility and HTML checks per month. Fully automated.

Let our automated scanner check your large sites using Axe Core and W3C Validator.
