LessHeadCMS is a free, open-source headless CMS written in PHP. You describe your content model as a PlantUML diagram, and LessHeadCMS generates the database, a paginated REST API and a clean editorial interface from it. It runs on ordinary shared hosting with PHP and SQLite – no Node.js, no Docker, no cloud subscription – and includes field-level permissions and approval workflows defined as text.

Features

  • Content modelling via PlantUML
  • Live schema changes with data backup
  • REST API
  • Editorial interface generated from schema
  • Media library
  • Users, roles, groups, and permissions
  • Editorial workflows in a textfile
  • Multi language (backend and frontend)
  • Runs on ordinary shared hosting - no SAAS/Cloud circus necessary
  • Free and open source under the GNU AGPL v3
