Octopress is a static blogging framework built on top of Jekyll. In order to start blogging with Jekyll, you have to write your own HTML templates, CSS, Javascripts and set up your configuration. But with Octopress all of that is already taken care of. It uses scripts to build static files to be deployed to a server. You can run locally, or even on your server and it will generate an entirely static web site for you. You can even rsync it to where you’re hosting from.
