Tenon

Tenon is a one of a kind accessibility testing tool in that it is aimed at offering unprecedented flexibility in tooling for designers developers testers and content authors. Tenon achieves these goals via its API which can be seamlessly integrated into your existing toolset. It doesn't matter what IDE you use, what CMS you use, what automated build and deploy tool you use, or what you use for unit testing, acceptance testing, or issue tracking, Tenon can be added to these workflows. This ability to test early and often allows you to catch and fix accessibility issues before they happen, not after, and allows you to release accessible code from the beginning.
