Squidex

What is Squidex?

Squidex is an open-source headless CMS built on MongoDB, CQRS, and Event Sourcing architecture. Unlike traditional content management systems, Squidex decouples content management from presentation, providing a structured API with OData filtering and Swagger definitions that developers can integrate with any frontend—whether web applications, mobile apps, or backend services. The platform is built with ASP.NET Core and designed to run on both Windows and Linux environments. It serves as a centralized content hub for teams that need flexible content distribution across multiple channels and systems. The headless approach allows developers to use their preferred technology stack for building user interfaces while Squidex handles content organization and delivery. Squidex offers structured content modeling, seamless integrations with external systems, and comprehensive API documentation. Being fully open source, it provides transparency and allows for self-hosting, giving organizations control over their content infrastructure without vendor lock-in. The platform is suited for development teams, digital agencies, and enterprises that require a modern approach to content management with API-first capabilities. Its architecture supports scalability and distributed systems, making it applicable to projects ranging from small websites to complex multi-channel content operations.
