Feedjack is a feed aggregator writen in Python using the Django web development framework.

Like the Planet feed aggregator:

• It downloads feeds and aggregate their contents in a single site
• The new aggregated site has a feed of its own (atom and rss)
• It uses Mark Pilgrim’s excelent FeedParser
• The subscriber list can be exported as OPML and FOAF

But FeedJack also has some advantages:

• It handles historical data, you can read old posts
• It parses a lot more info, including post categories
• It generates pages/feeds with posts of a certain category
• It generates pages/feeds with posts from a certain subscriber
• It generates pages/feeds with posts of a certain category from a certain subcriber
• A cloud tag/folksonomy (hype 2.0 compliant) for every page and every subscriber
• It uses Django templates
• The administration is done via web (using Django’s kickass autogenerated and magical admin site), and can handle multiple planets.
• Extensive use of django’s internal cache engine. Most of the time you will have no database hits when serving pages.
