About Pipes
Pipes is a powerful composition tool to aggregate, manipulate, and mashup content from around the web.
Like Unix pipes, simple commands can be combined together to create output that meets your needs:
- combine many feeds into one, then sort, filter and translate it.
- geocode your favorite feeds and browse the items on an interactive map.
- power widgets/badges on your web site.
- grab the output of any Pipes as RSS, JSON, KML, and other formats.

A few weeks ago we rolled back the V2 release. Today all Pipes are now running on the V2 engine!
Yesterday we migrated all Pipes to the V2 engine. We experienced some minor delays in the completion of the full migration.
It's been a little over a year since we first announced the V2 engine. After many months of work and help from the Pipes developer community, all Pipes now are running off our new V2 engine! Special thanks to hapdaniel and libra_sun for reporting issues and making V2 a better engine.
