The server provides a real‑time data‑sync layer for web, mobile and IoT applications. It maintains interactive JSON documents that are persisted and automatically synchronized across connected clients, while also supporting publish‑subscribe messaging, request‑response RPC calls, and presence monitoring to track online users and login/logout events.

Developers can configure the system entirely on the server side, linking it to existing caches, databases, message buses and other back‑end services without writing additional code. The platform enforces authentication and fine‑grained permission checks for each user and message, ensuring secure communication throughout the application.

Typical use cases include collaborative editing, live dashboards, chat systems, and any scenario where multiple clients need to react instantly to shared state changes or events. The software runs on macOS, is classified as stable, and is positioned as a core developer tool for building secure, reactive real‑time applications.
