About Nvda
NVDA (NonVisual Desktop Access) is a screen reader for Microsoft Windows. The project describes it as free and open source. It is developed by NV Access together with a global community of contributors. The repository page covers the source code, build tooling, tests, and project documentation. To download a copy, the page directs users to the main NV Access website.
NVDA is available under a modified GNU General Public License version 2 or later. The project has a development roadmap and a stated product vision and principles. The page describes it as a Windows-only tool, so it is not intended for other operating systems. The repository's own metadata lists the project as not open source, which conflicts with the description on the page, so the open source status should be checked against the license.
