XOWA (eXtensible Offline Wiki Application) is a free and open-source software application that enables users to store, browse, and search Wikipedia content offline. It is notable for being the first application to allow users to download and store the entire English Wikipedia to their device. XOWA allows users to view Wikipedia content offline, without the need of an internet connection, meaning they can access any Wikipedia page, even those that are not normally available offline. It also features a powerful search engine, allowing users to find the information they need quickly and easily. Additionally, XOWA also provides tools for creating, editing, and managing offline Wikipedia content. It is designed for use by both individuals and organizations, such as libraries and schools, as a reference and educational tool.
Discontinued The program seems to be no longer updated. The latest version, 1.3.0, released in June 2010, can still be downloaded from the official website.
