One thing that kept bothering me with website builders was that they increasingly tried to hide the technical parts of building a website. That's useful for many people, but I wanted almost the opposite — a visual tool for people who are already comfortable with HTML and CSS.
ThemesFor.app is my attempt at that.
You can build static websites from blocks, edit them visually, and export the HTML. I'm now working on taking the idea much further, but before I do, I wanted to put the current version in front of developers and see what they find useful—and what they don't.
It's still rough in places, so feedback is very welcome:
