Vienna

Vienna is a free, open‑source application for macOS that lets users subscribe to, organize, and read RSS and Atom feeds. It provides a native macOS interface for managing collections of news sources, displaying article headlines, summaries, and full content within the program. Users can add, remove, and categorize feeds, and the reader handles periodic updates to keep the displayed information current.

The software is targeted at anyone who wants a dedicated desktop client for aggregating web‑based news and blog updates on a Mac, including casual readers, researchers, and developers who prefer an offline‑capable, locally installed solution. Because it is open source, the code can be inspected, modified, or extended by the community.

Vienna’s distinguishing characteristic is its focus on the macOS platform, delivering a native experience without reliance on web services or proprietary formats. Its stable release status indicates that the core functionality for feed retrieval, parsing, and presentation has been mature and reliable for everyday use.
