How it works

1. Create an endpoint

Get a unique URL like /in/xK9mPqRt instantly. Point any webhook provider at it.

2. Webhooks arrive instantly

Watch requests appear in real time. Inspect every header, query param, and body — exactly as received.

3. Replay and debug

Resend any request to your local server or a staging URL. No need to trigger the same event again.

Built for developers

Real-time inspection

Requests appear instantly via WebSocket — no polling, no refreshing.

Full payload capture

Every header, query param, and body — JSON pretty-printed automatically.

One-click replay

Resend any captured request to any target URL without re-triggering the source.

Any HTTP method

GET, POST, PUT, PATCH, DELETE — all captured. Works with any webhook provider.

Enable / disable endpoints

Toggle any endpoint on or off. Disabled endpoints return a silent 404 — no information leaked.

Search & filter

Filter requests by body content or path (case-insensitive), narrow by HTTP method. Results update instantly.

HMAC signature verification

Enter your webhook signing secret and HookGrabber shows whether each request's signature is valid — supports GitHub and generic HMAC-SHA256.

Webhook forwarding Pro

Relay every incoming request to one or more destination URLs automatically. Per-rule enable/disable, delivery log included.

REST API Pro

Manage endpoints and fetch request data programmatically. Integrate with CI pipelines and scripts.
