Plagger is a pluggable Atom/RSS feed aggregator written in Perl.

Everything is implemented as a small plugin and you can mash them up together using Plagger core API and plugin hooks.

You can think of Plagger as a blosxom or qpsmtpd for RSS aggregator.

Plagger comes with various plugin API hooks so that third-party plugins can extend:

Subscription (Bloglines, Google Reader, My Yahoo!, OPML)
Custom Feed (mixi, Mailman, Google News)
Filter/Tag Content (, Technorati, URLBL, FeedBurner)
Smart Feed (Tag, Rating, Enclosure)
Widget on output (,, Technorati, Bloglines, Blogpulse)
Publish (Gmail, SMS, CHTML, Mobile Mail, XHTML, JavaScript, IMAP, NNTP, PSP, iPod, metaWeblog, Atom)

Plugins can be enabled / disabled using condition modules (= rule-based). So you can do "Forward all the updates to my Gmail account, but if the title contains 'Plagger' and bookmarked by 5 users on, SMS me as well."

By default, Plagger doesn't do anything with the 2 tough parts of aggregator: Crawling and User Interface, but lets other services/tools do it. My recommendation is to use Bloglines for Crawling and Gmail for User Interface (and Search).

Since rev7, Plagger comes with a dumb aggregator plugin that fetches RSS/Atom feeds synchronously. You can use OPML remote subscription and the Simple aggregator to consume a small number of feeds. It doesn't do de-duplication of feed updates yet.

We're in the active development right now. API and config file format might be changed in the future.
