## What it is
Backdrop CMS is a free, open-source, PHP-based content management system forked from Drupal 7, designed for non-technical users to build and manage websites. It ships with Views, responsive admin tools, and a built-in upgrade path from Drupal 7.

## Use cases
- build a blog or personal website without coding
- create a website for a nonprofit or school
- migrate an old Drupal 7 site to a maintained CMS
- run a fast CMS on cheap shared hosting
- manage website content with multiple user roles and permissions
- build an intranet or image gallery site

## When to choose
- you want an out-of-the-box CMS usable by non-developers
- you need an easy upgrade path from Drupal 7
- you want Views and admin tooling included in core
- you're deploying on shared hosting with PHP and MySQL

## When to avoid
- you need Drupal 8+ or Symfony-based architecture and ecosystem
- you want a headless or API-first CMS
- you need cutting-edge modern PHP framework features
- your team already invests heavily in the Drupal contrib ecosystem
