Event Gateway
A managed service that sits between an event source and your endpoint, handling delivery, retries, fan-out, and routing — Hookdeck, Svix, AWS EventBridge.
An event gateway acts as a managed middle-tier: providers send events to the gateway (or your service emits to the gateway), and the gateway handles fan-out to multiple consumers, retries, queueing during outages, and observability.
Examples: Hookdeck (inbound + outbound), Svix (outbound webhook delivery as a service), AWS EventBridge (event bus). They're priced by event volume and add 50–500ms of latency vs direct delivery.
You probably need a gateway when: you fan out one event to 5+ consumers, you need at-least-once delivery with SLA, or you're shipping a webhook product (you're the sender). For debugging and inspection, a webhook inspector like HookSense is the right tool — much cheaper, real-time visibility.
How HookSense helps
HookSense is positioned for inspection and debugging — not as an event gateway. For high-volume fan-out, pair HookSense with Hookdeck or Svix: HookSense inspects, the gateway delivers.
