Ionic Creator Drift Inc. has provided an excellent cloud service called Ionic Playground to build Ionic Apps and fiddle around with Ionic Framework. Ionic Playground is similar to JSFiddle where you can write/edit small Hybrid Apps using Ionic Framework with live preview. It also has the capability to save your app and resume work later using a unique URL. The URL can be shared with multiple people and anyone can fork it to add their own flavor to it. The URL is http://play.ionic.io.
