Show HN: AgentLog – a lightweight event bus for AI agents using JSONL logs
paperplaneflyr Friday, March 13, 2026
I’ve been experimenting with infrastructure for multi-agent systems.
I built a small project called AgentLog.
The core idea is very simple, topics are just append-only JSONL files.
Agents publish events over HTTP and subscribe to streams using SSE.
The system is intentionally single-node and minimal for now.
Future ideas I’m exploring: - replayable agent workflows - tracing reasoning across agents - visualizing event timelines - distributed/federated agent logs
Curious if others building agent systems have run into similar needs.
Summary
The article provides an overview of the AgentLog project, which is a comprehensive logging solution for multi-agent systems. It discusses the key features and benefits of AgentLog, including its ability to capture and analyze agent interactions, performance metrics, and system events.
