Frog is a static web site generator written in Racket.

You write content in Markdown or Scribble. You generate files. To deploy, you push them to a GitHub Pages repo (or copy them to Amazon S3, or whatever).

Posts get a variety of automatic blog features.

You can also create non-post pages.

The generated site uses Bootstrap, which is responsive, automatically adapting to various screen sizes.

Yes, it's very much like Octopress and others. But Frog doesn't require installing Ruby. Installing Racket is typically waaaay simpler and faster.

The only non-Racket part is optionally using Pygments to do syntax highlighting.
