Features
Everything you need to capture, inspect, debug, and route webhooks — from a free inspector to a full relay pipeline.

- ✓ Syntax-highlighted JSON with pretty/raw tabs

- ✓ Search and filter by method or body content
- ✓ Auto-refreshing live feed

Webhook relay & transforms Paid
Forward captured webhooks to one or more destinations. Transform payloads with templates, filter keys, inject custom headers, and get automatic retries with per-destination delivery logs.
- ✓ Fan out one webhook to many URLs
- ✓ Exponential-backoff retries
- ✓ SSRF-protected destinations (no internal targets)
Replay & mock responses
Re-send any captured request to a URL of your choice to reproduce bugs. Configure exactly what CanHook returns to the sender — status code, body, and content-type — to simulate your real endpoint.
