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.
