Your agents fail in ways
you can't see.

Without observability, every production issue is a fire drill.

🔔

Without TraceHawk: Agent crashes at 3am. You find out when users complain.

With TraceHawk: Real-time error alerts via Slack, email, or webhook.

💰

Without TraceHawk: $4,200 LLM bill with zero breakdown of where it went.

With TraceHawk: Per-agent, per-model cost attribution with budget limits.

🌲

Without TraceHawk: Agent picked the wrong tool. No idea why.

With TraceHawk: Decision tree view shows every branch and choice made.

How it works

Up and running in minutes.

01

Install the SDK

pip install tracehawk
# or
npm install @tracehawk/sdk

One package. Works with Python and TypeScript agents.

02

Add one decorator

import tracehawk
tracehawk.init(api_key="th-...")

@tracehawk.observe
def my_agent(prompt):
    # Your existing code
    return openai_client.chat(...)

Wrap your agent. Every LLM call, tool use, and decision is captured automatically.

03

See everything

# Open TraceHawk dashboard
# → Full span waterfall
# → Decision tree view
# → Cost per agent/model
# → Real-time error alerts

Live in seconds. No infrastructure to manage, no SDK rewrites.

Comparison

Purpose-built for AI agents.

Langfuse and LangSmith are great — for LangChain. TraceHawk is framework-agnostic.

"We had no idea our research agent was spending $200/day on embeddings until TraceHawk flagged it. Saved us before the bill hit."

ML Engineer · Stealth AI startup

"The decision tree view is the killer feature. Finally I can show my team exactly why the agent chose to call that tool."

Sarah Park
AI Engineer · Series B fintech

"Migrated from LangSmith in an afternoon. Works with our custom agent framework — no LangChain required."
