Hookmetry is an AIโ€‘powered webhook debugging and observability platform built for developers who need reliability in eventโ€‘driven systems.

Webhooks often fail silently after migrations, connector deprecations, or schema changes โ€” leading to missed events, broken workflows, and frustrated teams. Traditional inspection tools only show payloads, but they donโ€™t explain why signatures fail, retries multiply, or payloads drift. Hookmetry was designed to solve these hidden problems.

Key Capabilities: - Payload & Schema Drift Detection โ†’ Catch renamed fields, encoding mismatches, and subtle format changes before they break production.
- Signature Validation & Replay โ†’ Verify HMAC signatures against raw requests and replay events safely to reproduce failures.
- Retry & Delivery Insights โ†’ Track retries, ordering, and latency to understand why events arrive late or multiple times.
- Observability for Webhooks โ†’ Treat webhooks as distributed events, not just callbacks โ€” with visibility into headers, raw bodies, and delivery context.

Why Developers Choose Hookmetry: - Purposeโ€‘built for debugging โ†’ Unlike generic API monitors, Hookmetry focuses on the unique failure modes of webhooks.
- Realโ€‘world pain coverage โ†’ From Microsoft Teams connector deprecations to Stripe signature mismatches, Hookmetry addresses the issues developers face daily.
- Lightweight integration โ†’ Works alongside existing tunneling or inspection tools (Ngrok, RequestBin, Webhook.site) but adds deeper intelligence.

Ideal For: - SaaS teams migrating webhook endpoints.
- Developers debugging signature errors or payload mismatches.
- Engineering teams needing observability into retries, ordering, and delivery failures.

Questions & Answers

As answered by people managing Postman and Hookmetry.

What makes your product unique?

Hookmetry's answer:

Hookmetry is an AI-powered webhook telemetry and observability platform built for modern development teams. Webhooks are the nervous system of modern software, connecting services like Stripe, Clerk, and GitHub to your application. However, when they fail, they fail silentlyโ€”causing lost revenue, broken user onboarding, or out-of-sync databases.

Hookmetry acts as an intelligent proxy that captures, decodes, and reconstructs every webhook event. It gives developers full visibility into raw headers, payloads, response times, and cryptographic signatures. With advanced features like one-click replays, local server forwarding, and an AI-powered diagnostic engine, Hookmetry reduces webhook troubleshooting time from hours to seconds.

Why should a person choose your product over its competitors?

Hookmetry's answer:

Most competitors only inspect payloads or provide basic forwarding. Hookmetry goes deeper:

  1. Zero-Configuration Setup: Create secure public endpoints in one click. You can start capturing and inspecting live webhooks from any provider in under 5 seconds.
  2. Bulletproof Security & Trust: Cryptographic signature validation happens automatically. Stop guessing why your Stripe, GitHub, or Shopify signature verification failed; Hookmetry checks them in real-time.
  3. Massive Time Savings (One-Click Replay): No more waiting for Stripe or GitHub to retry a failed webhook. Select the failed event, click "Replay," and send the exact original payload back to your handler.
  4. No-Setup Local Tunneling: Easily forward webhooks to your local machine (http://localhost:3000) to test and develop webhook-dependent features locally.
  5. Frictionless Collaboration: Share encrypted debug sessions with teammates or third-party API support staff with secure, shareable links, avoiding copy-pasting messy JSON payloads into Slack.
  6. AI Diagnostics Engine: When a webhook fails, Hookmetry analyzes headers, body content, and provider-specific schemas to tell you exactly what went wrong and how to fix it.

This makes Hookmetry the developerโ€™s debugging companion, not just another inspection tool.

Who are some of the biggest customers of your product?

Hookmetry's answer:

Since Hookmetry is still earlyโ€‘stage, itโ€™s focused on individual developers and small SaaS teams testing webhook reliability. As traction grows, we can list customers like:

โ€“ SaaS startups migrating webhook endpoints

โ€“ Indie developers debugging Stripe/Razorpay integrations

โ€“ Teams needing observability into retries and payload drift

How would you describe the primary audience of your product?

Hookmetry's answer:

Hookmetry is built for:

  • Backend & Full-Stack Developers building integrations with third-party SaaS APIs (payment gateways, authentication providers, communication platforms).
  • QA & Testing Engineers simulating complex event-driven user journeys without manually triggering actions in dashboard sandboxes.
  • DevOps & Platform Teams monitoring API health, latency patterns, and retry behaviors in staging and production systems.
  • Technical Support Engineers diagnosing issues for customers who report that "events aren't syncing" between platforms.

Its audience is technical, handsโ€‘on, and focused on reliability in production systems.

What's the story behind your product?

Hookmetry's answer:

Hookmetry was born from a founderโ€™s frustration with silent webhook failures during SaaS migrations. Existing tools showed payloads but didnโ€™t explain why signatures failed or retries multiplied. The product was built to solve real developer pains, starting with Stripe and Razorpay signature mismatches, and has grown into a platform for webhook observability and debugging.

Which are the primary technologies used for building your product?

Hookmetry's answer:

Hookmetry is engineered for ultra-low latency event ingestion, high availability, and real-time telemetry rendering. To achieve this, the platform is built on a modern, robust, and highly reliable technology stack:

  • Backend Engine (Node.js & Fastify): Our core ingestion layer is powered by Fastify, a next-generation, low-overhead Node.js web framework. Fastify is benchmarked to process HTTP requests up to 2x faster than Express, ensuring that incoming webhooks are acknowledged with microsecond-level response times.
  • Real-Time Data Layer (PostgreSQL & Redis): We utilize PostgreSQL for ACID-compliant storage of persistent configurations, user accounts, and metadata. In parallel, Redis handles high-speed caching, dynamic rate-limiting, and real-time event streaming to deliver instant updates to the frontend dashboard.
  • Interactive Dashboard (React & Vite): Powering a lightning-fast, highly responsive single-page dashboard. Vite ensures sub-second development updates and extremely optimized production bundles.
  • Sleek Interface (Tailwind CSS & Recharts): Crafted with a developer-first, high-fidelity user interface. Tailwind CSS powers a responsive, dark-mode native design with fluid transitions, while Recharts renders real-time telemetry, response times, and failure patterns in intuitive visual charts.
  • Security & Validation Layer: Native, cryptographic verification engines supporting automated signature checks for Stripe, GitHub, Shopify, Razorpay, Svix, Clerk, Twilio, and custom HMAC configurations.
