Cromwell CMS

Cromwell CMS is an open-source headless CMS written in TypeScript for building websites with React and Next.js. It aims to offer a WordPress-like experience, with an extensive admin panel and a plugin and theme system, so that content creators with no programming background can use its features.

Main features include store and blog management, a drag-and-drop theme editor, installation of themes and plugins from an official store, and free full-featured store and blog themes. A built-in database layer works with SQLite, MySQL, MariaDB or PostgreSQL. Developers can use Next.js, Nest.js, TypeORM and TypeGraphQL alongside the CMS API to build any kind of site.

Cromwell is MIT licensed, with documentation, demo websites for the frontend and admin panel, and a Discord community. It suits teams who want WordPress-style editing but a modern React front end.
