A small and lighting fast in-browser HTML editor with syntax highlighting and instant preview for code you type. It is a great tool for HTML prototyping since you do not have to save the file everytime you want to make the changes. On top of that it's only single HTML file and works offline too.
You can think this app as a diet version of CodePen.io or JsFiddle but you can run it locally. It has two main windows -- left is used for code editor and the right one is used for HTML preview. For syntax highlighting it uses an awesome CodeMirror library.
HTML Editor support following features.
- Open file from local disk
