Reddit debate: multi-agent systems still lack a production-grade communication substrate
One_Two_2229 · reddit · 2026-09-20
A developer running multi-agent systems in production argues there's no communication layer purpose-built for agentic workloads. Teams currently cobble together Kafka + Redis (heavy ops overhead), homegrown queues or DB-as-a-bus (no replay, fragile), or framework primitives from LangGraph/CrewAI/AutoGen (vendor lock-in, state explosion on long-running tasks). All share the same gaps: no out-of-the-box replay, no audit trails, no semantic search or summarization over agent decisions — bolting on Langfuse or Opik just adds another disjointed system. The post asks how others handle agent-to-agent messaging and debug message flow in production.
