Banjo is a blogging application with bells and whistles, written using the Django framework. It supports caching and skinning. It is suitable for any blog, but is most appropriate for integration into an existing Django application, such as a Satchmo store or a forum. It supports multiple blogs from one installation, each with their own skin. The blogs can be served from unique domain names, from subdirectories, or from subdomains with equal ease, without special configuration. Trackback and Pingback are supported and you can use standard blogging tools such as Ecto, Mars Edit, or ScribeFire to post to the blog.

GitBlogger is a small tool that allows you to write blog posts in reStructuredText using an editor of your choice, commit your posts to a git repository, and then have them automatically converted to Blogger blog posts when you push your repository to another repository.

PySite is not a CMS in the traditional sense. Rather, you manage the contents of a Web site via a file manager interface, which gives you access to all settings (pages, styles, plugins, etc.). Compose your pages with Jinja templates, and edit your code comfortably with syntax highlighting in the ACE editor. You may write your stylesheets in Sass and let the integrated compiler write CSS files. PySite also contains a facility to manage virtual mailboxes, in case you maintain your own SMTP and IMAP server, e.g. with Postfix and Dovecot.
