Jifty -- Just Do It. Jifty is yet another web framework. Jifty tries not to make you say things more than once. Out of the proverbial box, Jifty comes with one way to do everything you should need to do: One database mapper, one templating system, one web services layer, one AJAX toolkit, one set of handlers for standalone or FastCGI servers. We work hard to make all the bits play well together, so you don't have to.
