Frog is a static web site generator written in Racket.
Posts get a variety of automatic blog features.
You can also create non-post pages.
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.
