Textpattern CMS is completely free, open source software and it's built upon proven web technologies too. Furthermore, it doesn’t muddy your HTML with additional code dependencies or script libraries. Textpattern has a powerful tag-based template language that’s easy to learn and provides a wealth of ways to structure a website and manipulate content. We purposefully keep the core of the CMS lean and responsive. However the system is fully extendable via plugins, of which there are hundreds available. Over 21 years of development has been lovingly poured into our CMS. The active, friendly and helpful community surrounding the platform ensures its continued success and guides its future. Our CMS ships with built-in support for Textile and has support for Markdown with a plugin. Alternatively, you can write plain text or vanilla HTML if you so wish.
Uses MySQL as its back-end.
Pb is a tiny CMS for creative coders. Create a beautiful blog just from Markdown files. Drag and drop them to your /posts folder. Portabloc will do the rest. Pb is a minimalist CMS, lightweight and easily customizable. For those who want to create simple and modern sites without complex deployments: No database, no Javascript, no bloat. Requires PHP v5.03 or later with mbstring enabled and mod_rewrite (which pretty much means Apache).
Extremly simple "static" PHP blog that renders markdown posts. No installation or database needed. To create a post just write a new .md file. Everything else just works.
Note: It's not a full blogging platform, does not currently come with any premade themes, it's just a script and specific folder structure to load and display markdown files. The demo site looks pretty good as-is, though.
Requires PHP v5.x or later and a web server that supports .htaccess (Apache and Lightspeed, though I don't see why you couldn't write some rules for Nginx).
MediaCMS is a modern, fully featured open source video and media CMS. It is developed to meet the needs of modern web platforms for viewing and sharing media. It can be used to build a small to medium video and media portal within minutes.
It is built mostly using the modern stack Django + React and includes a REST API.
Designed for personal use only. If you want people to be able to create accounts, you can do that. If you want it to be "everybody but me can only watch thigns," you can do that. If you want the entire install to be private and requiring logins from everybody, you can do that, too.
Postlight's Awesome CMS is a collection of open and closed source Content Management Systems (CMS) for your perusal.
HybridAuth is a library for web apps which implements social sign-ins (meaning, you authenticate with an existing social network account (like Twitter or Facebook)) rather than applying for an account with an e-mail address. Lets the user import established profiles and contact lists from the socnet account they logged in with. Also has a library of plugins for existing frameworks and applications, from Drupal to Concrete to Wordpress. Written in PHP so that it'll run on just about every webhost out there out of the box.
MDwiki is a single-page wiki engine implemented as an HTML5 page with JavaScript. Drop a bunch of Markdown documents into a directory, add a copy of mdwiki.html, and you now have a fully functional wiki. You can't edit it with your web browser but it's fine as a mostly static CMS or a documentation site.
