Like other folks here I also made something similar for myself. It started as a jsbin clone, but then I wanted to play with tweaking the environment itself. So now it's become a single editable directory tree where both the editor and the actual projects/demos share common parts of code, all synced between local storage and the server. If I break the editor and refresh the page, there's a simpler alternative editor backup to fix it. Lots of fun with such setup!

Here's a screenshot with the editor showing a preview when editing itself: https://imgur.com/a/RxMCrlf
