Frictionless and free

No setup required — just paste the URL. Comes with a live request feed, verbatim payloads, and library of mock webhooks from 150+ providers.

A URL that's a starting point

Forward requests to localhost via the Hookdeck CLI, then move to Event Gateway to get queues, retries, transformations, and observability.

Agent-ready

Out-of-the-box support for agents: share your URL to get started. Advanced workflows available with skills and MCP.
