Atomic Server is an open-source headless CMS and real-time graph database designed for developers building dynamic, collaborative applications. It provides a powerful, lightweight backend with features like custom data modeling, real-time synchronization, and robust search capabilities, enabling rapid development of complex data-driven applications.

How It Works

Built on Actix-web and Sled, Atomic Server boasts sub-millisecond median response times and an 8MB download size with no runtime dependencies. Its core is an event-sourced architecture utilizing Atomic Commits for robust versioning and history. Data modeling is highly customizable via an Ontology Editor, enforcing schemas and enabling sharable models. Full-text search is powered by Tantivy, offering fuzzy matching and fast query responses. Real-time synchronization is achieved via WebSockets, allowing instant state updates to clients.
