Plagger is a Perl-based software that serves as a pluggable aggregator for RSS and Atom feeds. It is highly customizable and can be extended through its plugin architecture.
The software comes with a variety of plugin API hooks that allow third-party plugins to expand its functionality in several areas. Subscription plugins like Bloglines, Google Reader, My Yahoo!, and OPML are available. Additionally, custom feed options such as mixi, Mailman, and Google News, as well as, filter and tag content with del.icio.us, Technorati, URLBL, and FeedBurner. The software also features smart feed options as well as widgets, like del.icio.us, Digg.com, Technorati, Bloglines, and Blogpulse.
Plagger also allows users to publish content across a variety of channels. For instance, users can publish content to Gmail, SMS, CHTML, Mobile Mail, XHTML, JavaScript, IMAP, NNTP, PSP, iPod, metaWeblog, Atom, among others. Plugins can also be enabled or disabled according to the user's specifications, and this can be done through condition modules, which operate on a rule-based system.
One of the best features of Plagger is its ability to forward all updates from subscriptions to the user's Gmail account or any other preferred email platform. It can also send SMS notifications for specific articles using pre-set alerts or certain patterns defined by the user.
Plagger is designed to allow other services or tools to take care of the two essential parts of any aggregator- crawling and user interface- instead of doing them itself. The integration is straightforward, allowing users to use Bloglines for crawling and Gmail for user interface and search.
Plagger rev7 has a simple aggregator that fetches RSS/Atom feeds synchronously. One can consume a small number of feeds using OPML remote subscription and the simple aggregator. However, it doesn't do de-duplication of feed updates yet.
Currently, the software is still in active development, which means that the API and config file format might change in the future. Nonetheless, Plagger is a top-notch software for Atom/RSS feed aggregation, and it comes with an array of helpful features that make feed reading a breeze.
