Vienna is an RSS/Atom reader for macOS.
Vienna can connect directly to the websites you want to track. Additionally or alternatively, you can also sync with a server supporting the Open Reader API (an adaptation of the now deceased Google Reader API). Vienna has been successfully tested with BazQux.com, FreshRSS.org, FeedHQ.org, InoReader.com and TheOldReader.com.
Since version 3.6, Vienna requires a minimum of macOS 10.11 (El Capitan).
Vienna 3.5.x requires a minimum of macOS 10.9 (Mavericks).
Vienna 3.1.x requires a minimum of OS X 10.8 (Mountain Lion).
Vienna 3.0.x requires a minimum of OS X 10.6 (Snow Leopard).
Vienna is also available as a Cask for Homebrew Cask.
brew install --cask vienna
If after reading the forum and asking your questions there, you are convinced that there is a problem in Vienna's code or an important feature is missing, you may open an issue on Github.
Be concise, but as precise as possible to allow other people reproducing the issue. To keep things short, you can provide a link to a relevant thread or message on the Cocoaforge forum.
Want to contribute? Great! There are many ways you can, even if you aren't a developer.
Please check CONTRIBUTING.md.
We need help keeping Vienna translations up to date into different languages. You can contribute localizations at Crowdin. Registration is required, but the account is free. If you want to contribute for a language that is not yet listed, then contact us. Do not localize the project's *.strings files directly. Localizable *.plist files have to be localized directly.
Vienna supports a variety of different display styles for articles. These styles are provided on the Styles sub-menu off the View menu. A style is a combination of an HTML template that is used to control the placement of various parts of the article and a CSS stylesheet that controls the appearance of the article.
You can write styles by referring to this document. Have a look at existing styles in the Styles folder.
Vienna supports plugins which are installed in menus and/or on the toolbar and can run defined actions. These plugins are XML-based and can be created by editing a simple .plist-file without any knowledge of Cocoa programming, in as little as 15 minutes.
