Dossier is an open-source toolkit for building custom headless CMS solutions, developed by Jonas Bengtsson. Rather than being a ready-made CMS, it provides the foundational libraries and APIs that allow developers to assemble their own content management system while retaining full ownership of the data, authentication, and hosting infrastructure.
Key Features of Dossier
- Bring-your-own-auth architecture that integrates with any existing authentication and authorization solution
- Support for PostgreSQL and SQLite databases, including in-memory SQLite for browser-based and local test environments
- Auto-generated TypeScript types and GraphQL schema from content model definitions
- Flexible access control supporting both editorial and user-generated content within the same database
- Lightweight enough to run a full stack in the browser, yet scalable for production PostgreSQL deployments
Who Should Use Dossier
Dossier is aimed at TypeScript developers who want to build a tailored headless CMS deeply integrated into their own application rather than adopting a pre-built platform. It suits projects where teams need granular control over auth, storage, and content access patterns — particularly applications that combine editorial workflows with user-generated content under a single data layer.
