help Rocket Validator FAQ

What does Rocket Validator check on a website?

Rocket Validator crawls a website and checks HTML with the W3C Validator and accessibility with axe-core. It can follow internal links from a starting URL instead of testing only one manually selected page.

Can Rocket Validator find WCAG accessibility problems?

Yes, its accessibility scanner uses the axe-core engine to identify many WCAG-related issues. The results are automated checks, so they should be supplemented with human testing such as keyboard and screen-reader review.

Does Rocket Validator crawl more than one page?

Rocket Validator is designed to spider internal pages recursively from a starting URL. Its documentation describes crawl limits that vary by plan, including smaller limits for Micro accounts and larger limits for Pro and Agency accounts.

Does Rocket Validator have a free option?

Rocket Validator offers a free trial for HTML validation, while advanced accessibility checks and scheduled reports are associated with paid or Pro trial features. The service is operated as a web application, so testing takes place through its online dashboard.
