Squidex

Squidex is an open-source headless CMS and content management hub designed for structured content and an API-first workflow. It provides a web UI for editors while developers consume content via robust APIs to power websites, apps, and backend services.

Key Features

• Schema-based content modeling for structured, reusable content
• REST API with OpenAPI/Swagger definitions and advanced querying (OData-style filtering)
• GraphQL endpoint, including support for real-time subscriptions
• Workflow and role-based permissions to control draft, review, and publishing processes
• Content versioning with history, comparisons, rollback, and audit-oriented change tracking
• Event-driven integrations and automation hooks to connect external systems
• Asset management and import/export tools, including CLI-based administration
• Built-in backup and restore capabilities for migrations and recovery

Use Cases

• Centralized content backend for websites, mobile apps, and multi-channel publishing
• Product catalogs, marketing pages, and structured content for multiple frontends
• Content hub integrated with internal systems via events and APIs

Limitations and Considerations

• Requires external database infrastructure and careful sizing for high-scale deployments
• API-first approach means frontend rendering must be implemented separately

Squidex is well-suited for teams that want a flexible, developer-friendly headless CMS with strong APIs, workflows, and operational tooling. It can be deployed via containers or platform-native setups and scaled for production workloads.
