About Squidex
Squidex is an open-source headless CMS and content management hub. Unlike a traditional CMS, it provides an API-first back end and leaves the user interface to you, whether that is a website, a native app, or another server. It is built with ASP.NET Core and CQRS, tested on Windows and Linux, and released under the MIT license.
Its API supports OData filters and publishes Swagger definitions, making it easy to integrate with other tools. For storage it works with MongoDB, PostgreSQL, MySQL, or SQL Server. The project documents its roadmap on Trello and uses a community forum for feature requests, help, and bug reports.
Development requires Visual Studio Code or Visual Studio 2022, Node.js, and one of the supported databases. Squidex suits teams that need structured content with workflows and APIs to feed multiple channels, especially developers in the .NET ecosystem. A hosted version is offered on squidex.io.
