Kodi is a free open source media player and entertainment center for multiple platforms, including Android, Linux, MacOS X, iOS, Windows, and Xbox One. It is also available as a downloadable app from Google Play and Microsoft Store.
Kodi was originally known as Xbox Media Center (XBMC) and developed by the XBMC Foundation, a non-profit technology consortium. It plays audio, video, and image files, and third-party plugins are available to add additional features. The Kodi Wiki page lists more details about configurations and options for this app.
