Alkaline is a PHP content management system (CMS) for creative professionals and small businesses that is designed to be used alone or in conjunction with your own proprietary code. The application handles posts as well as images, and can manage both raster (GIF, JPEG, and PNG) and vector graphics (PDF, SVG). The software features customizable themes, extensions, and more. It can be used by novices (for example, drag-and-drop social network integration) and advanced users (for example, overriding the theme engine). It works with most Web server software, including Apache and Windows Server.
