freeboard.io – Dashboards For your #InternetOfThings / #IoT projects
freeboard.io is simple, real-time, interactive dashboard to visualize IoT data. It provides drag & drop customize-able interface.
Similar to github, in free plans you can use unlimited devices but your dashboard should be public, for private dashboards you may have to switch to paid plan.
The software code powering freeboard.io is released under open source in github: https://github.com/Freeboard/freeboard
