A permanent capture URL
Point any provider at a stable endpoint that accepts everything and never drops an event — even when your real endpoint is down.
Inspect everything
Raw headers, the exact bytes of the body, a parsed JSON tree, query params, timing and source IP — searchable and filterable.
Verify provider signatures
Auto-detect Stripe, GitHub, Shopify, Slack and Twilio, surface the event type, and verify the signature with a clear pass / fail badge.
Replay & resend
Re-fire any stored event, edit the payload before sending, or bulk-replay a filtered range to your endpoint.
Forward to localhost
One command — npx @marrona/webhookharbor forward — streams live events to your machine over a durable channel with offline buffering.
Auto-relay with retry
Forwarding rules relay matching events to your destinations and retry with backoff, with alerts when something keeps failing.
