Self-Hosted And Embeddable HTML-CSS-JS Playground: Editr

Many web designers and developers use code sharing websites like jsFiddle or Codepen.

Editr is a simple and self-hosted app (that doesn’t use any server-side code) for creating a similar interface for editing/improving and sharing any HTML-CSS-JS projects.

Sharing can be done by simply embedding an instance on it (this is done with jQuery) to any web page.

The app uses the beautiful Ace Editor which can be themed with ease and offers a great experience while editing code.
