Obraz — static site generator in a single Python file mostly compatible with Jekyll
Since the last 0.2.1 release several people have started to use Obraz for their sites. The only site with open sources that I'm aware of is labs.dendiz.com.
I keep a list of sites using Obraz. If you run your site on Obraz and you want to put a link to it on the Obraz homepage, feel free to send me an email or open a pull request.
