Feed Funnel is a Python utility for aggregating multiple feed sources (RSS or Atom; anything that feedparser can handle) into JSON data sources that can be easily templatized into HTML or feed formats.
funnel.py takes one or more feed URLs as positional arguments and produces JSON on stdout, e.g.
$ funnel.py http://www.theverge.com/rss/index.xml > theverge.json
Usage: funnel.py [options] URL1 [URL2 [...]]
Options:
-h, --help show this help message and exit
-L LIMIT, --limit=LIMIT
How many items to include in the output (default: 100)
