What is HookNexus?
HookNexus is a real-time webhook debugging platform for developers. Generate a unique public URL, point your third-party service at it, and instantly see every incoming HTTP callback — headers, body, query params, and all.
The Problem
If you’ve ever integrated with APIs from Stripe, GitHub, Shopify, or any service that sends webhooks, you know the pain:
| Pain Point | What Happens |
|---|---|
| No public IP | Your localhost:3000 can’t receive callbacks from the internet |
| Blind payloads | You deploy first, then check server logs to see what was sent |
| Lost history | Webhook events are fire-and-forget — miss one and it’s gone |
| Expensive retesting | Reproducing a specific event means re-triggering the whole flow |
| Signature headaches | HMAC verification fails and you have no idea why |
How HookNexus Solves It
- Instant URL — Sign in, create an endpoint, and get a public URL in seconds.
- Real-time dashboard — New requests appear as they arrive; no manual refresh.
- Full inspection — See method, headers, query parameters, and body with syntax highlighting.
- Signature verification — Built-in tools for common providers (Stripe, GitHub, Shopify, Slack) and related APIs.
- Plus extras — API key, HTTP push, log export, advanced signature modes, and custom responses (see Pricing).
