While the need for web accessibility was not envisioned when the Americans with Disabilities Act was signed into law 30 years ago this summer, ADA web accessibility has emerged as a top-of-mind topic and a fundamental necessity.

This has prompted a proliferation of new tools to evaluate the accessibility of websites. While a majority of these tools were designed to support current Web Content Accessibility Guidelines (WCAG 2.1) they vary in the number and types of errors they detect and the degree to which they can help ensure ADA Accessibility compliance.
