Jitsu is an open source toolset for building cool, innovative web apps. Apart from the hip appellation, Jitsu features an XML markup language, page compiler, animation engine, Ajax, and runtime inspector, among other things.
Its implementation of Ajax makes it designer friendly, which is crucial for building consumer web applications. It’s got client-side data binding to make for rapid iterations, meaning changes are easy to achieve without having to rebuild everything from the ground up. And Jitsu is free. It makes it easier for programmers to build front end apps that users will appreciate.
Other features include a compiler which converts markup to javascript, javascript runtime, cross platform library and backbutton support. Jitsu works best with Firefox and IE. It doesn’t require any particular back-end server solution.
