HookReplay

Capture and replay webhooks for debugging and testing

The Problem

Webhooks fail silently. When something goes wrong, developers cannot reproduce the exact payload that caused the issue. Testing webhooks requires triggering real events.

The Solution

A proxy that captures all incoming webhooks. Replay any webhook with one click. Modify payloads for testing. Compare expected vs actual responses.

RequestBin captures but does not replay. Svix focuses on sending, not receiving. No tool combines capture, replay, and debugging for incoming webhooks.

Why Now?

Webhook-first APIs are everywhere. Payment, communication, and DevOps all rely on webhooks. Debugging tools have not kept pace with adoption.
