NVDA

A free, open-source screen reader for Windows developed by NV Access. NVDA provides speech and braille output, enabling blind and low-vision users to interact with the operating system, web browsers, and applications. Since its release in 2006, NVDA has become one of the most popular screen readers globally, particularly valued for being freely available without a commercial licence. It is frequently used alongside JAWS in accessibility testing to ensure compatibility across screen reader implementations.
