Oobee (formerly known as Purple A11y) is an accessibility site scanner - a customisable, automated web accessibility testing tool that allows software development teams to find and fix accessibility problems to improve persons with disabilities (PWDs) access to digital services. The official application can only be downloaded at https://go.gov.sg/oobee.
