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.
Simblog aims to be one of the most easy-to-use and lightweight blogging platforms. It emphasizes user experience, workflow, and ease of use without neglecting usability and extensibility. It will take full advantage of what HTML5 and CSS3 have to offer without delving too deeply into experimental features. It is built on its own lightweight framework, which allows a high degree of extensibility and modularity for your blog. It uses Smarty as a templating engine (which also provides a caching mechanism), jQuery and Kendo UI for frontend design, and MySQL as a database.
