About

This is a very simple front end prototyping tool...
very similar to codepen BUT...
It works offline...
Instantly previews your html, css and javascript (js) code.

As simple as it is... I'm dedicated to constantly updating and dealing with issues that arrive.

There are other tools on the chrome store that I used to use... but i found that the developers are not as active wrt updating them.

Some lack features which I would like to personally use so I decided to create Prototype.

Any feedback is highly appreciated.

Thanks!
