About CatchHook

Catchhook is a webhook testing and debugging service. A developer gets a live temporary endpoint URL, points a webhook provider at it, and sees each incoming request captured in full. The service identifies supported providers, such as Stripe and GitHub, and shows the event and signature details next to the raw payload.

Captured requests can be replayed, or relayed to a local development server through a fast-ack relay that answers the provider immediately with the configured reply and finishes delivery to the local machine afterward, so provider timeouts do not get in the way. The product also covers email ingress, endpoint actions, an API and an MCP server, with documentation and a changelog. A temporary endpoint works without signup and expires after two days; accounts begin with a free trial.
