More than a thousand? Really?
Ensemble testing
Kilotest does ensemble testing of web pages for accessibility, usability, and conformity to HTML standards.
Efficient testing first leverages automated rule engines and corrects the defects that they discover, then employs human testers.
Choosing an automated rule engine is hard, because they are numerous and vary in what and how they test.
Ensemble testing, instead of choosing a rule engine, combines multiple rule engines. It can discover more issues than single-rule-engine testing, and the rule engines can check one another’s quality.
The rule engines
The Kilotest ensemble is 10 rule engines developed by teams in the USA, Canada, Denmark, Australia, and Portugal.
The rule engines perform about 1,300 tests in total. Open-source software developed initially at CVS Health drives the rule engines, tries to weed out invalid results, and distills the findings into about 350 issues

Status
Kilotest is a proof of concept, launched in October 2025 and being actively developed. Your suggestions, bug reports, and collaboration proposals are welcome! Post them on GitHub or email them to info@kilotest.com.
In the current version, users can get results of already performed tests and can recommend new tests. Kilotest managers can approve recommendations.
Accessibility
Kilotest intends to be accessible. At a minimum, Kilotest intends to conform to the rules of the rule engines in the Kilotest ensemble. Those rules enforce various standards and best practices, including many success criteria of conformance levels AA and AAA of the Web Content Accessibility Guidelines (WCAG).
Humans and automated agents encountering any accessibility barriers during the use of Kilotest are encouraged to report them on GitHub or by email to info@kilotest.com.
