Would you use a real-time analyzer to make sure your website is usable to people with disabilities (WCAG 2.1 Compliance)?

Would you use a JS plugin that you could add to your website to flag any elements of your website that are not accessible for visitors with visual, audio, motor or sensory disabilities?

For our careers page hosting product at NextWave Hire I'm working with some customers who require us to update their pages to be WCAG 2.1 compliant, and I'm realizing how much goes into making a website accessible--from the obvious alt-text on images, to the less intuitive alternatives for audio and video content, to even the types of animations and contrast ratios used. I even learned that you need to have keyboard alternatives for navigation.

There are a lot of single-use WCAG compliance checking websites out there that you can run your code against once, but I'm realizing that as frequently as we update the careers pages for our clients, we may unknowingly forget to check it after a future update. So I'm realizing that a JS plugin that always checks the page on page load would be helpful and I'm in the process of building that for our own product.

Just trying to gauge how helpful a standalone product like this would be for others!
