Webhook Guides

Hookdeck Alternative

Hookdeck popularized the idea that webhooks need an operational layer instead of a pile of ad hoc endpoints. Its public docs describe gateway capabilities such as receiving, delivery monitoring, retries, replay, and reliable processing.

FastHook is a Hookdeck alternative for teams that want a source to connection to destination model, direct request/event/attempt evidence, local CLI delivery, first-class Google Sheet and Gmail destinations, and a focused workflow for debugging and replaying failed webhooks.

Decision model

QuestionWhat to evaluate
Do you need provider-specific ingress?Signature presets, challenge responses, allowed methods, and source URLs.
Do you need operational routing?Filters, transformations, branch-local retries, and destination auth.
Do you need recovery?Attempt history, response bodies, retry controls, replay windows, and idempotency guidance.
Do non-engineers need data?Google Sheet and Gmail destinations can turn events into rows or messages.

FastHook model

FastHook keeps the webhook path explicit. A source receives and verifies traffic. A connection decides which branch should receive the event and what processing should happen. A destination performs delivery and records the attempt.

  • Use one source per provider, tenant, or environment when secrets differ.
  • Use multiple connections when the same provider stream fans out to separate owners.
  • Use destination auth to prove outbound traffic came through FastHook.
  • Use retry and replay only after the receiver can handle duplicate delivery.

Example filtered connection

Route payment failures
curl -X POST "https://api.fasthook.io/v1/connections" \
  -H "Authorization: Bearer fhp_xxx" \
  -H "x-team-id: tm_3b5335b627084a838b" \
  -H "Content-Type: application/json" \
  -d '{

      }
    ]
  }'

Comparison boundaries

This page does not claim that every Hookdeck feature has a one-for-one FastHook equivalent. For any production migration, compare the provider list, auth methods, retry controls, replay limits, destination types, observability exports, pricing, and compliance needs against your actual workload.

Migration checklist

  1. Inventory every current source URL, provider secret, destination URL, and retry policy.
  2. Create FastHook sources per provider and environment so signing secrets stay isolated.
  3. Recreate routing as connections and test filters against stored payload examples.
  4. Send traffic to mock or staging destinations before switching provider dashboards.
  5. Replay only a narrow verified window after the cutover to prove recovery behavior.

Where FastHook is intentionally focused

FastHook is built around operational clarity for webhooks: which request arrived, which event was created, which destination attempt failed, and what should be retried or replayed. That focus matters when the webhook stream is tied to billing, order fulfillment, identity lifecycle, or developer automation.

Review note

This comparison avoids pricing and unverified plan details. It is based on public Hookdeck pages reviewed on June 17, 2026.
