# Hooklistener

> Hooklistener is a webhook gateway and visual debugger for developers. It captures, inspects, replays, and routes webhook payloads with automatic retries, monitoring, and alerts. The platform provides HTTPS endpoints for testing, 14-day payload retention, localhost tunneling via CLI, email-to-webhook inboxes, and real-time WebSocket debugging.

Hooklistener helps development teams debug webhook integrations from services like Stripe, GitHub, Slack, Shopify, and Twilio. Key capabilities include payload inspection with syntax highlighting, one-click replay to any environment, shareable debugger links, inactivity monitors for silent failures, and a CLI for local development tunneling.

## Core Features

- **Debug Endpoints**: Instant HTTPS URLs that capture every webhook with 14-day searchable history
- **Payload Inspector**: Syntax-highlighted JSON viewer with header inspection and AI summaries
- **Replay Engine**: Send webhooks to production, staging, or localhost with response diffing
- **Localhost Tunneling**: CLI command `hooklistener tunnel` exposes local servers to the internet
- **Email Inboxes**: Receive emails at @hookinbox.com addresses, converted to HTTP webhooks
- **Inactivity Monitors**: Alerts via email or Slack when expected webhooks stop arriving
- **WebSocket Debugger**: Capture and replay WebSocket, Socket.IO, and MQTT messages
