5 Best Free/Open-Source Feed Readers (Desktop Clients) for Linux

Even though there are plenty of good web-based RSS/News readers or aggregators that are available today, a lot of us still prefer to use desktop feed readers. This is mainly because desktop clients are more flexible and offer integration with other installed applications.

For Linux users, there are many desktop-based RSS/news readers to choose from. But before you look further, you may already have one that comes with your distro so better try it first. If it's not for you, then perhaps you may like any of the following desktop-based RSS feed readers that in my own opinion are some of the best:

Liferea

Liferea (abbreviation for Linux Feed Reader) is a GTK-based reader that goes along well with the GNOME desktop. It aims to be fast and easy to use and distinguishes itself from other UNIX feed readers by avoiding lots of package dependencies. Liferea support search folders, which allow the user to have permanent searches. Each search folder contains all headlines that do match its user-defined search rules. To easily read linked articles, Liferea can view websites using an embedded browser, which can be either be Mozilla/Firefox/XulRunner, GtkHTML, or Webkit. In addition, users can configure many predefined external browsers to open links with.

Akregator

If you are a KDE user, then you may already Akregator installed. Akregator is part of KDE desktop since version 3.4, and it is distributed with the kdepim module. It is designed to be both easy to use and to be powerful enough to read hundreds of news sources conveniently. Akregator can be configured to fetch feeds within regular intervals. The user can also manually request to fetch all feeds, individual ones, or those in a selected category. It supports feed icons and embeds KHTML as an internal, tabbed web browser. Aside from Konqueror, any external browser can also be called.

RSSOwl

RSSOwl is a Java-based aggregator that uses SWT as a widget toolkit to remain consistent in terms of look and feel across different operating systems. Here are some of the best features of RSSOwl:

* Generate PDF / RTF / HTML documents from any news including aggregations
* Powerful Newsfeed search engine working with keywords
* Integrated Newsfeed validator
* Perform a fulltext-search with result-highlight on favorites and categories
* Full support for RSS & RDF versions 0.91, 0.92, 1.0, 2.0
* Support for Atom Syndication Format version 1.0
* Read news either in the internal browser or a Rich Text window
* Aggregate news of an entire category to one newstab
* Store newsfeeds in Blogrolls and share them with other people

Eclipse RSS Reader

Aside from having the basic features of a desktop feed reader, Eclipse RSS Reader offers a number of advantages in comparison to other solutions since it is built on the Eclipse platform. Like Eclipse's extension points together with its plug-in based architecture support addition of new RSS format translators without changing the core application.

Mozilla Thunderbird

Mozilla Thunderbird is both news and e-mail client that is developed by the Mozilla Foundation. It has tons of great features like its support for extensions and themes while remaining simple and fast. It also has a reliable and quick search function. I have been using Mozilla Thunderbird for quite some time now, and I must say that it has all the important features that I need.

I know there are other great desktop-based RSS feed readers for Linux out there that I failed to include here, so it's up to our dear readers to mention them via comment.
