AtomicServer
Headless CMS and real-time graph database for Atomic Data
AtomicServer is an open source headless CMS and real-time graph database built around the Atomic Data model. It provides a structured, schema-driven way to create and query data, plus a web UI for editing content and building collaborative apps.
Key Features
- Schema and ontology tooling to define custom classes, properties, and validation rules
- REST API with JSON-oriented responses and multiple serialization formats for linked data
- Real-time synchronization for clients using WebSockets
- Full-text search with fuzzy matching and operators
- Table editor with keyboard and copy/paste workflows (Airtable-like)
- Collaborative rich-text documents
- File management for uploading, downloading, and previewing attachments
- Authorization model with read/write permissions and hierarchical structures
- Event-sourced versioning and history tracking
- Optional AI integration via MCP, with support for using hosted models or local model backends
Use Cases
- Building schema-driven internal tools and business apps with real-time UIs
- Headless CMS for structured content with powerful search and custom data models
- Collaborative knowledge bases and document-centric workflows with permissions
Limitations and Considerations
- Project status is marked as alpha; breaking changes may occur before a 1.0 release
AtomicServer is a strong fit when you need a flexible data model, fast querying, and real-time collaboration in a self-hosted stack. Its SDKs and built-in editors help bridge backend data modeling with modern web app front ends.
