A free and open source .NET content management system designed for delivering diverse digital experiences.

Umbraco CMS is an open-source content management system built on the .NET framework. It functions as a server-side web application used to create and manage digital experiences across various platforms. The software provides a dedicated backoffice interface for content administration and allows developers to build custom website structures tailored to specific organizational needs. It operates as a web framework that manages the relationship between content storage and front-end delivery.
Deployment occurs via the .NET Runtime and SDK on Windows, Linux, and MacOS. Users initialize projects using specific .NET templates and run the application through the command line interface. The system is designed to be extensible, allowing developers to modify the functionality and add new capabilities without altering the core source code. This approach ensures that the application can scale from simple websites to complex digital platforms while maintaining a stable foundation.
The software is built using C# and .NET Core, making it suitable for developers and enterprises familiar with the Microsoft ecosystem. It follows a community-driven development model where contributions to the source code are managed through GitHub. The architecture emphasizes a separation between the core system and custom extensions, meaning the base installation serves as a foundation that developers expand upon. This design allows for the integration of various third party tools and custom business logic within the .NET environment.
