Dashing is a Sinatra based framework that lets you build beautiful dashboards. You can use premade widgets, or fully create your own with css, html, and coffeescript. Widgets harness the power of data bindings to keep things simple.
You can also use the API to push data to your dashboards, or make use of a simple ruby DSL for fetching data. It supports Drag & Drop interface for re-arranging your widgets. You can host your dashboards on Heroku in less than 30 seconds. Dashing was originally created at Shopify for displaying custom dashboards on TVs around the office.
