Directus

Summary
Directus is an open-source headless CMS and backend-as-a-service that provides instant REST and GraphQL APIs for any SQL database. It features a data studio for visual data modeling and content management, robust access control, and a visual workflow automation builder. Directus aims to accelerate backend development by providing a production-ready platform for managing complex content structures and user permissions.
Rationale
Directus is a headless CMS and backend-as-a-service that allows developers to connect to any SQL database and instantly get REST and GraphQL APIs. It offers a visual data modeling interface, granular policy-based authentication, and a visual automation builder for workflows. While it provides a 'Studio' for managing content and data, it's not a drag-and-drop UI builder for building full applications in the same vein as Retool, but rather for managing the data and content itself. It supports self-hosting and offers extensive customization and extension capabilities.
