# WebhookWhisper

> WebhookWhisper is a free webhook testing, inspection, and forwarding tool for developers. Get a unique HTTPS endpoint instantly — no signup required. Inspect incoming HTTP requests in real-time, forward webhooks to multiple destinations with retry logic, and fire test payloads from 35+ providers including Stripe, GitHub, Shopify, Razorpay, PayPal, Twilio, Slack, and more.

## What it does

- **Webhook inspection**: Receive any HTTP POST/GET/PUT/PATCH/DELETE request and display full headers, body, query params, and metadata in real-time via WebSocket
- **Webhook forwarding**: Set rules to relay incoming webhooks to one or more target URLs (including localhost) with configurable retry logic
- **Test sender**: Send authentic sample payloads from 35+ webhook providers with one click — no waiting for real events
- **Event replay**: Re-fire any previously received event to any target URL
- **API access**: Automate webhook testing via REST API with API key authentication (Pro plan)
- **Event history**: 7-day history on free plan, 30-day on Pro

## Plans

- **Guest** (no account): 1 temporary endpoint, expires in 1 hour, last 50 events visible
- **Free** ($0/month): 3 permanent endpoints, 2 forwarding rules per endpoint, 7-day event history, 35+ test payloads
- **Pro** ($9/month): Unlimited endpoints, unlimited forwarding rules, 30-day history, API key access, event replay, priority support

## Supported webhook providers (sample payloads)

Stripe, GitHub, Shopify, Razorpay, PayPal, Twilio, Slack, SendGrid, Mailchimp, WooCommerce, HubSpot, Salesforce, Intercom, Zendesk, Paddle, Lemon Squeezy, Cashfree, Square, Braintree, Plaid, PagerDuty, Datadog, Linear, Notion, Airtable, Typeform, Calendly, Zoom, AWS SNS, Vercel, Netlify, CircleCI, GitLab, Bitbucket, and more.

## How it works

1. Click "Create Free Endpoint" — get a unique HTTPS URL in under 1 second, no account needed
2. Paste that URL into your webhook provider (Stripe dashboard, GitHub repo settings, Shopify webhook config, etc.)
3. Trigger an event on your provider — watch the request appear in real-time with full headers and body
4. Optionally set a forwarding rule to relay the request to http://localhost:3000 or any other server

## Alternatives comparison

WebhookWhisper vs webhook.site: WebhookWhisper adds webhook forwarding with retry logic and 35+ one-click test payloads. webhook.site only provides inspection.

WebhookWhisper vs RequestBin: WebhookWhisper is actively maintained with real-time WebSocket updates, forwarding, and test payloads. RequestBin was shut down.

WebhookWhisper vs Hookdeck: Hookdeck is a paid enterprise tool. WebhookWhisper is free for most developer use cases.

WebhookWhisper vs ngrok: ngrok tunnels your local server. WebhookWhisper receives webhooks and optionally forwards them — no local agent or binary required.
