What is it?

Squidex is a headless content management system. Instead of bundling a website theme, it provides a content API with OData filtering and Swagger definitions, so you can build the frontend as a website, a native app, or another backend service.

The project is built with ASP.NET Core and uses CQRS as its architecture. The README states it is tested on Windows and Linux with modern browsers. Content can be stored in MongoDB, PostgreSQL, MySQL, or SQL Server, and a Docker image and several cloud deployment templates are provided, including Azure, AWS, GCP, Heroku, Kubernetes, and Render.

A hosted version is available at cloud.squidex.io for those who prefer not to run the server themselves.
