Coq au Vin is a blogging engine written in Chicken Scheme. It is designed to appeal to users who have basic Web development skills (i.e., who know HTML and CSS), are able to install their own server-side software, and would rather edit a template than press 105 buttons to customize their sites.
OpenLaunch is a Web-based content management system that integrates a broad array of services into a single, fully-featured, elegantly designed Web site. The project aims to eliminte the difficulty of integrating multiple systems into a single Web site by implementing a blog, forum, Web pages, wiki, and (coming soon) E-Commerce and support tickets. It is built around the Torpedo Framework, an open MVC framework which includes support for controllers, forms, and a large number of other very useful utilities.
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.
Chyrp is a blogging engine designed to be very lightweight while retaining functionality. It has powerful theme and extension engines, so you can personalize it however you want. The code is well-documented, and it has a very strong structure that's loosely based on the MVC design pattern. Chyrp allows importation from several different blogging engines and uses a system called "feathers", which are basically templates for custom posts.
Sandbox is a personal Web site package that provides you with a blog, image gallery, file download area, and the ability to create miscellaneous custom Web pages. Many other blog/Web site packages like Wordpress only do one thing. Most blog packages do not also provide a good image gallery or a good downloads module. You can get these things in separate packages, but integrating them into one site is difficult, involving code bridges and incompatible skinning systems. Sandbox aims to have all of these things integrated into one package.
ShinyCMS is a content management system intended for use by Web designers and Web developers who want to keep a clear distinction between the markup they create and the content their clients can edit. Designers add templates to the CMS, which define page layouts containing editable elements. Users can then build pages by selecting an appropriate template and editing the elements it contains. This approach means that editing content is a simple and safe process, and the site look and feel is kept consistent and professional.
