Smashing is a Sinatra based framework, used to build beautiful and impressive dashboards. The project is a fork of Dashing, an excellent framework created by Shopify for displaying custom dashboards on TVs around their offices.

Smashing has a drag & drop interface for re-arranging the widgets positions and many premade widgest, ready to be used. Developers can also build custom widgets, to display data from multiple sources (Simple Ruby DSL for fetching data from databases or online resources).

Here is a live demo → of a simple dashboard with realtime update. You can host your Smashing dashboards on Heroku in less than 30 seconds.

Okay this is not a brand new product, but we couldn't forget to suggest one of the best report designers ever made. BIRT is a mature and complete open source technology platform, used to create data visualizations and reports that can be embedded into rich client and web applications. BIRT is a top-level software project within the Eclipse Foundation, an independent not-for-profit consortium of software industry vendors (like IBM, OpenText and Innovent Solutions) and an open source community.

BIRT has two main components: a visual report designer within the Eclipse IDE for creating BIRT Reports, and a runtime component for generating reports that can be deployed to any Java environment. The BIRT project also includes a charting engine that is both fully integrated into the report designer and can be used standalone to integrate charts into an application.

More information on the project website.

BIRT is available for download here.
