Ally’s accessibility checklist is based on WCAG 2.1 AA (Web Content Accessibility Guidelines). This is an international accessibility standard, and most of the new legislation and legal requirements worldwide aligns with this standard.

Additionally, Ally also adds a number of additional checks on top of this that start to target the usability and quality of the content a bit more.
