Drupal is a content management system and web application framework used by thousands of individuals, businesses, non-profits, government, and other organizations throughout the world for creating personal and corporate websites, e-commerce sites, social networking sites, intranets, and much more.
Drupal is popular because it provides a powerful, scalable, low cost, high value solution to manage and grow an Internet presence. It is also open source, which means the code is freely available to anyone to use and modify. This means no license fees and no vendor lock in.
Drupal is supported by a passionate community of thousands of developers who continuously work to enhance the functionality and security of Drupal to enterprise levels and beyond. A community this large means that you’ll never be stuck without support if your developer goes out of business and you’ll have free access to future upgrades and security enhancements.
