Everything You Need to Debug Event-Driven Systems

Stop wasting hours debugging mysterious async failures. Hookmetry does the heavy lifting.

Real-Time Event Monitoring

Capture and inspect every webhook, AI callback, or automation event your application receives. View headers, payloads, and signatures instantly.

Automatic Signature Validation

Validate Stripe, GitHub, and custom HMAC signatures automatically. Identify authentication failures before they reach your logic.

Reconstruction Engine

Proprietary heuristic engine that piece-by-piece reconstructs failed events to identify structural mismatches and signature gaps.

Adaptive Intelligence

Goes beyond static error codes. Automatically detects advanced failure patterns across Stripe, n8n, GitHub, and custom agents.

Event Replay

Test your endpoints by replaying captured events. Perfect for development and debugging without waiting for external triggers.

CLI Intelligence

Run `hookmetry diagnose` from your terminal to get probable causes, framework-specific fixes, and reconstruction summaries locally.

Built for Modern Architectures

From legacy webhooks to next-gen AI agent callbacks.

Webhook Integrations

Debug Stripe payment confirmations, GitHub repository events, and Shopify updates. Automatically validate HMAC signatures and detect middleware mutations.

AI Agent Callbacks

Monitor async responses from LangChain, OpenAI structured outputs, or custom MCP tool calls. Instantly see why your agent failed to parse a response.

Workflow Automations

Catch failures in n8n, Zapier, or Make workflows before they silently drop critical data. Reconstruct the exact JSON payload that caused the crash.

How It Works

Get failure intelligence in minutes, not hours.
