Heron watches your agents from the network, not the code
Heron calls itself Wireshark for AI agents, and the analogy is exact. Instead of asking you to wrap your agent in an SDK or route everything through a proxy, it sits passively on the network and watches the LLM traffic go by. From that wire it reconstructs what your agents are actually doing, which tools they call, the multi-step plans they follow, where the time and tokens go. No code changes, no sidecar, off the request path. It already profiles Claude Code, Codex, Hermes, and OpenClaw, and it's open source under Apache-2.0.
That last part is the pitch. Every other observability tool, and there are something like fifteen of them fighting over agents right now, wants you to instrument your code or add a middleman that can slow things down or go down with you. Heron's bet is that you can get most of the picture by just reading the traffic, the way a network engineer debugs without touching the app.
Agent observability is suddenly a real market. Coralogix just raised $200M betting on it, AgentX launched one-click agent debugging last week. The reason is obvious: as agents run longer and chain more tools, it failed somewhere stops being good enough, and nobody wants to rip apart prod to find out where. The wire-tap approach is the lazy-in-a-good-way version. Whether passive reconstruction is detailed enough to replace instrumentation is the open question, but the framing is right.
