Squidex

an opensource headless cms, a cms with an api. a place for all your content. you can create schemas to define the structure of your content, e.g. which fields it has and how you want to edit them. you can also define validation rules to ensure that your content is consistent. the management ui helps you to create and edit the content, but the heart of the system is a rich api, which supports filtering with odata query options and creates swagger definitions for your content. therefore you can easily integrate your content to your clients, e.g. to a website, mobile app or another server application.
