Freeboard - Dashboard for Internet of Things

Freeboard is a turn-key HTML-based "engine" for dashboards. Besides a nice looking layout engine, it provides a plugin architecture for creating datasources (which fetch data) and widgets (which display data)— freeboard then does all the work to connect the two together. Another feature of freeboard is its ability to run entirely in the browser as a single-page static web app without the need for a server.
