Oobee overview

What Oobee is

Oobee is an automated accessibility testing tool that scans web pages against the Web Content Accessibility Guidelines (WCAG) and reports the issues it finds. It lets software development teams check whether their digital services are usable by persons with disabilities (PWDs) before and after release.

Oobee opens each page in a real browser, runs the axe-core accessibility engine plus Oobee’s own checks, and groups the results into Must Fix, Good to Fix and Needs Review. The Oobee command-line interface (CLI) and the @govtechsg/oobee npm module are built and maintained by the Government Technology Agency of Singapore (GovTech). The Oobee Desktop application is a separate product with a graphical interface.
