Jaggery is a framework to write webapps and HTTP-focused web services for all aspects of the application: front-end, communication, server-side logic and persistence in pure Javascript. One of the intents of this framework is to reduce the gap between writing web apps and web services. Jaggery is open-source and released under Apache 2.0.

As a pure Javascript server-side scripting engine, Jaggery combines all the strengths of Javascript with flexibility and freedom at both the development and deployment stages. Most JavaScript webapp development mechanisms restrict developers to a framework-specific structure or patterns, which demand an additional learning curve. By contrast, with Jaggery, any developers who are versed in Javascript have everything they need to get going.
