Backdrop CMS is a simple, lightweight, and easy to use Content Management System for building professional websites.

Backdrop is a Content Management System. A CMS is a database driven website that allows people to log in, and if they have permission, it allows them to edit nearly any page on the website. Backdrop can be used to create a wide variety of websites. Use Backdrop CMS for everything from a single-administrator's personal blog site, to a complex, multi-role, business e-commerce site. Backdrop is the perfect fit for comprehensive non-profit, educational, corporate, or government websites.

Backdrop is a tool for building websites. Backdrop's core software is packed full of features that should meet the needs of 80% of all websites. Backdrop's world of Add-Ons can be used to meet less common needs. Backdrop can be easily extended with the addition of modules (that change the way it works), themes (that change the way it looks), and layouts (that change where content can be placed on a page).

Backdrop CMS is a fork of Drupal. Backdrop's founders and early contributors saw the huge changes in Drupal version 8, and met the need to maintain and improve on the pervious version. Backdrop is software with a proven track-record of success. By providing an easy upgrade from Drupal 7, it will be the logical next step for most sites running on Drupal 7 today.
