Flextype Flextype

Flextype is super fast headless content management system with an elegant architecture and built-in smart cache.

While most things in Flextype are designed to be simplistic and intuitive. It falls short when it comes to image and file management within the admin panel itself. I find working with images tedious, as there is no way to upload multiple images, or manipulate images from the admin panel.
Flextype provides REST API out-of-the-box, with compact JSON payloads that gives you full programmatic control over your content management system. Allowing you to develop applications for mobile devices as well as the web.
With Flextype you can define unlimited content types with unique behavior and custom fields. If you have used WordPress before, you a probably familiar with custom post types which are used to extend WordPress beyond a regular blog. In Flextype these are called entries and can be used to create any content type that is both easy to manage from an administration perspective as well as providing developers with the flexibility to build dynamic applications.

Grav Grav

Grav is a modern free and open source flat-file content management system. With Grav, you can publish content and build sites in a fast, flexible and simple manner with the file-based web platform. Grav requires zero installation and is just an zip archive that can be extracted to start using the CMS. Grave also comes with a powerful package management system that allow you to extend the feature set of Grav CMS. With the package management system you can install and upgrade themes and plugins written specifically for Grav. The software is written in PHP and released fully free and open-source under the MIT License.

Caching is an integral feature of Grav that has been baked in from the start. The caching mechanism that Grav employs is the primary reason Grav is as fast as it is. This is achieved with the Doctrine Cache library which support various caching backends including APCu, Memcache, Redis and WinCache.
With Grav's multisite setup you can create and manage a network of multiple websites, all running on a single installation of Grav.
