I've been using mustache templates a lot lately and thought I'd try to streamline my process.

So this is my take on jsFiddle/dabblet/etc, with inputs for data (JSON), structure (HTML), and style (CSS). On keypress, they get bundled up and injected into an iFrame. They're persisted with localStorage and export out as data URIs.

I'm looking for feedback and bug reports, edge cases are fine. This is a tool I built to suit my own needs, so I admit it won't be for everybody, but I'm open to requests.

Also let me know if the copy needs work. I wrote it to appeal to other frontenders, but I don't know...
