JSServe
Easy way of building interactive applications from Julia. Uses Hyperscript to create HTML descriptions, and allows to execute Javascript & building of widgets. It also supports an offline mode, that exports your interactive app to a folder, and optionally records a statemap for all UI elements, so that a running Julia process isn't necessary anymore.
