Concrete CMS
Open-source content management system for teams, written in PHP, with a built-in REST API and a MySQL or MariaDB database.
www.concretecms.comrepositorydocs
Concrete CMS keeps its content in a MySQL or MariaDB database and exposes it through a built-in REST API that authenticates with OAuth2, as the REST API introduction describes. The installation guide offers two paths: moving the zip archive into a web-accessible folder, or creating a project with Composer.
Worth knowing
The system requirements page states a minimum PHP version for the current line that it also says is past end of life.
