Jay Hollywood

We've only been using Rocket Validator a short while but it's been incredibly powerful in helping us validate multiple large sites in a very short amount of time. It has quickly become an invaluable tool in our website QA process.

Rocket Validator simply makes checking websites for HTML and Accessibility issues a breeze. It's so easy to use, performs validation on a regular basis using a schedule, allows us to check hundreds of pages per site and provides us with automated emails detailing the problems it finds. We've been using it since 2015 to validate the ecommerce sites we develop, I've no idea how we managed without it!

Rocket Validator is a powerful and straightforward tool. It not only helps us make a better product but it also improves our development process.

Luis Herrero

One of the key factors in robust web development is markup validation. There are some tools that help you in this task, but none of them is as fast and complete as Rocket Validator.
And my students love it!

David Gil

CTO at Ideas4all. Madrid, Spain

Web accessibility is a really important field impacting millions of potential users worldwide, and yet it is still quite under-prioritized by most development teams. We weren't the exception, until a potential project came up and we needed assessment and roadmap to compliance, and we needed that quick. Rocket Validator proved to be very useful in providing understanding on our current status on HTML and A11Y validation across all the pages of our sites. Information was obtained fast and easily and provided us with the details we needed just in time. No other approach out there looks so simple and efficient. Right now Rocket Validator is a common tool in our toolbox.

Webmaster of www.OrientalOutpost.com. San Diego, USA

The days of validating HTML 5 one page at a time are over! If you have hundreds or thousands of pages to validate, Rocket Validator can scrape your whole site and in a matter of minutes give you actionable information about pages that need help. Until I found Rocket Validator, this was a task that took hours, (and honestly, rarely got done).

Nick Weaver

Senior Web Developer at University of Wisconsin–Madison. Wisconsin, USA

I’ve used various tools for running site-wide markup and automated accessibility testing and none come close to Rocket Validator for its speed, its ease of use and its clear and concise reporting of errors.

Jarrad Langdon

Web / Graphic Designer at Jala Design. Sydney, Australia

Rocket Validator has provided our development team with the confidence in knowing that our client's websites are performing to the best of their abilities. Prior to using this service, our sites were reviewed manually - this was a process that took time and was not completed in a consistent method. Now that we are making use of Rocket Validator we are not only saving time, but we are also seeing the excitement in fixing both HTML and Accessibility issues. Overall it's an excellent tool that has dramatically improved our development cycle.

HTML validation is key in creating high quality web sites, but often misregarded, as validating large sites can be tedious. Luckily, we've got Rocket Validator to automate this process, just submit a starting URL and it will validate thousands of pages from your site in minutes.
Think of it as a tool to find the needles in the haystack!
