 Squidex is an open source headless CMS and content management hub. In contrast to a traditional CMS Squidex provides a rich API with OData filter and Swagger definitions. It is up to you to build your UI on top of it. It can be website, a native app or just another server. We build it with ASP.NET Core and CQRS and is tested for Windows and Linux on modern browsers.
