In their own words
Total Validator
Total Validator is a freemium tool for checking website accessibility, HTML, CSS, broken links and spelling. Automated accessibility checks cover WCAG 2.2, 2.1 and 2.0, US Section 508 and ARIA standards. It validates HTML and XHTML against W3C and WHATWG standards, and CSS against W3C standards. The product runs through web, Windows, macOS, Linux, an API and a browser extension, with CI/CD integration. Jenkins, Team City and Selenium can call the CI version, which also provides a Web API. Remediation guidance is included. Pro can test authenticated pages, intranets, private websites and JavaScript-generated DOMs through browser extensions, while returning results locally for security. The free Test version shows only a one-page issue summary. Basic handles one page at a time; whole-site and multiple-site validation are Pro features. Manual review tools and mobile testing are not provided.
