Real-Time Core
@ManagedService with transport-agnostic Broadcaster pub/sub. WebSocket, SSE, long-polling, and gRPC — auto-negotiated per client. Rooms, presence, message history, and interceptors built in.
Atmosphere
Real-time for the JVM — WebSocket, SSE, gRPC, rooms, presence, and AI streaming. From classic pub/sub to multi-agent orchestration, one framework does it all.
AI / LLM Platform
@Agent with pluggable AgentRuntime — auto-detects Spring AI, LangChain4j, Google ADK, or Embabel. Tool calling, conversation memory, filters, cost metering, and multi-model routing.
Multi-Agent Orchestration
@Coordinator + @Fleet for multi-agent systems. Parallel fan-out, sequential pipelines, and weighted routing. MCP, A2A, and AG-UI protocols for agent interoperability.
24-Chapter Tutorial
Build a complete real-time application from scratch. Covers transports, rooms, AI streaming, MCP, clustering, channels, and production deployment.
