Platformus is simple, developer-friendly content management system (where everything can be changed or replaced). You can describe and store your content, and it is totally separated from its representation, so you can represent it using the HTML pages, API, or any other way you want.
As any other ASP.NET Core web application, our system can run on Linux, Mac, and Windows (also, it can run in a cloud). It supports different storage types (PostgreSQL, SQLite, SQL Server, Azure SQL Database). It is modular, multilingual and multicultural. And it is open source and absolutely free.
While Platformus CMS is absolutely flexible for the developers, it is still very easy to use, and it is still comfortable and friendly for the end-users. You can make your users to see the only one backend section they need, with the single field to type text in. The backend is intuitive and well-structured.
