You find IFTTT too much closed and limited by the proposed channels count ? You’ve tested Zapier, but don’t want to pay for it ? If you have a small Linux at disposal, like a Raspberry PI, and you accept to put your hands in sludge, then Huginn is made for you !
Huginn is a Ruby on Rails application which allows listening of various events to trigger actions. For example, you can get notified by mail when rain is forecasted in your area, or when a subject is mentioned more than usual on Twitter, or even create a RSS feed from any website that doesn’t publish one. Wiki is available on Github, and contains enough information to get an idea. It is more complexe as IFTTT and more like Yahoo! Pipes, as you can chain data between many treatment agents.
