Zembly (styled zembly) was a browser-based development environment from Sun Microsystems that enabled social programming of applications for Facebook, Meebo, OpenSocial, iPhone web applications, and other social platforms, as well as web widgets. Users of zembly interacted with one another via zembly's social networking features to engage in co-development of applications for these platforms.
In addition to the development environment, the zembly platform, provided the ability to consume Web APIs ( RESTful web services) in zembly applications as well as externally using the open source zembly client library (with language bindings for Java and JavaFx). This functionality provided a consistent programming model across various API providers.
Zembly combined features from traditional IDEs (such as a rich scripting editor) with wiki- and social-networking-based technologies to attempt to innovate on the application development paradigm for smaller-sized applications. Applications created at zembly were automatically and transparently deployed, hosted, and scaled on its underlying cloud computing infrastructure.
