One click, thousands of checks
When you maintain a large site, manually checking each single web page for accessibility and HTML issues is just not an option.
For a typical site with 1,000 web pages, individually validating each page on the W3C Validator and Deque Axe Core means making 2,000 individual checks. If it takes you 5 seconds to perform each check, this means almost 3 hours just to get the results!
There's a much simpler approach. Leave the hard work to our web spider.
Just give as a starting URL, and we'll check as many web pages as you want. You control the number of pages to check, the validation speed and the kind of checks you want to perform on each web page found.
Test your sites at different screen resolutions
Because your sites don't look the same on a laptop, an iPhone, a Kindle Fire, or a Galaxy Note, they can have different issues at different screen resolutions.
Now with Device Viewport Emulation you can choose from a list of popular devices to emulate their screen resolution, device scale factor, User Agent string and orientation.

Simple, actionable reports
Having thousands of validation results for individual web pages is a lot of noise, unless you can group and prioritize it.
When you check different web pages on the same site, you typically get the same validation results over and over, because they share the same layouts and content widgets.
By grouping the common errors you get a high level overview of the most important issues and see a clear path of action.
Our summary reports will quickly show what needs to be fixed first, by grouping together and prioritizing the common issues on your web pages.
