What is Heron?
Heron is a passive observability platform for AI agents that reconstructs agent behavior, tool calls, and LLM interactions directly from network traffic without requiring SDKs, proxies, or code changes. It works by analyzing .pcap files or live TLS traffic at the host boundary, providing zero-intrusion monitoring of agent performance metrics like TTFT, latency, throughput, and error rates. Designed for developers and teams operating AI agents who need visibility into system behavior without instrumentation overhead.

Frequently Asked Questions about Heron
Do I need to modify my agent code to use Heron?
No. Heron requires zero SDK integration and zero code changes. It works by analyzing network traffic passively.
What traffic sources does Heron support?
Heron can replay .pcap files containing LLM traffic or capture live TLS traffic at the host boundary.
What metrics does Heron provide?
Heron provides TTFT (time-to-first-token), latency, throughput, error rate, per-agent performance mix, and reconstructs agent turns and tool calls.
Do I need special privileges to run Heron?
No. Heron can run with user-level permissions and does not require sudo or elevated access.
How does Heron work without a proxy or SDK?
Heron is passive - it reconstructs agent behavior and LLM interactions directly from network traffic itself, off the wire or at the TLS boundary.
