A complete toolkit for webhook development - CLI for local testing, SDK for type-safe handlers.

Better Webhook

Two tools, one goal: make webhook development delightful.

The Problem

Building webhook handlers is painful:

No local testing — You need to expose localhost with ngrok or similar tools just to receive webhooks during development
Trial and error — Testing requires triggering real events (pushing code, creating issues) repeatedly
No type safety — Webhook payloads are untyped any objects, leading to runtime errors
Manual verification — Implementing HMAC signature verification correctly is error-prone and tedious
No replay — When something breaks, you can't easily re-test with the same payload

Better Webhook provides two independent tools that solve these problems:

Capture real webhooks, replay them locally, and test with pre-built templates. No ngrok required.

Type-safe webhook handlers with automatic signature verification. Works with Next.js, Express, NestJS, and GCP Cloud Functions.

Need	Tool
Test webhooks locally without exposing ports	CLI
Replay captured webhooks during debugging	CLI
Use pre-built webhook templates	CLI
Visual dashboard for webhook management	CLI
Type-safe webhook handlers in production	SDK
Automatic signature verification	SDK
Zod schema validation for payloads	SDK

Starting local development? → Get started with the CLI

Building webhook handlers? → Get started with the SDK

Both tools work great together but are completely independent. Use whichever fits your needs.
