Hookdeck or Sendora — pick the trade-off, not the marketing.
Hookdeck is a polished webhook gateway — inbound transformation, outbound delivery, replay, signature verification. You still ship product events into it from somewhere. Sendora's webhooks module ships the same delivery posture (HMAC-SHA256 signed, exponential backoff, replay, delivery log, SSRF-guarded inbound) directly inside the platform that emits 50+ canonical events across auth / push / email / sms / billing / support. One signed subscription captures the whole taxonomy. If your stack is mostly Sendora, Hookdeck is doing work the platform already does internally.
Inbound webhook gateway + outbound delivery. Sits in front of every webhook your stack handles. You ship product events into it.
Same gateway posture (inbound SSRF guard + outbound signed retries), bundled with the event source that triggers most of them.
Side-by-side
| Capability | Hookdeck | Sendora |
|---|---|---|
| Outbound HMAC-SHA256 delivery + retries | ✅ | ✅ Stripe convention header |
| Inbound webhook receiver + transformations | ✅ rich transformation rules | ✅ receive + SSRF guard, no transformation DSL |
| Delivery log + replay | ✅ | ✅ + bulk replay by event filter |
| Rotating signing secret with overlap | ✅ | ✅ |
| Source taxonomy bundled (auth / push / email / etc.) | ❌ — you ship product events in | ✅ 50+ canonical types |
| Visual flow builder for inbound payload reshaping | ✅ | ❌ — receive raw, transform in your handler |
| Pricing model | From ~$50/mo Free → $200/mo Mid → enterprise | Bundled, no per-event markup |
Why teams switch to Sendora
- If your event source is Sendora anyway, Hookdeck is a per-event tax on data Sendora already emits.
- One signed subscription per endpoint instead of stitching multiple Hookdeck connections.
- Bulk replay by event filter — useful after a downstream outage when 30K queued auth events need a retry pass.
When Hookdeck is the right call
- You need Hookdeck's visual transformation builder for inbound payload reshaping — Sendora's inbound surface is receive + verify, no transformation DSL.
- Your stack is mostly NOT Sendora; Hookdeck's gateway-in-front pattern is the right shape for fragmented event sources.
- You operate a webhook gateway as a product (multi-tenant gateway-as-a-service) — Sendora isn't built for that.
Common questions
Cost comparison?
Hookdeck has a free tier; Mid tier is around $200/mo. Sendora bundles delivery with the rest of the platform. If you'd otherwise pair Hookdeck with Sendora-emitted events anyway, the Hookdeck bill is fully replaceable.
Can I still use Hookdeck IN FRONT of Sendora?
Yes — point Sendora's outbound webhooks at a Hookdeck source URL. You get Hookdeck's transformation layer on top of Sendora's signed payloads. Cost-only-redundant if you've already paid for both, but architecturally valid.
Inbound transformations?
Sendora's inbound endpoints receive raw signed payloads + run the SSRF + replay guards. Transformation logic lives in your handler (parse + reshape). If you need visual transformation rules, Hookdeck wins on that dimension.
Webhooks
One signed subscription to the whole platform's event taxonomy — Stripe / Svix delivery posture, zero per-event bill.
Svix Pro is $490/mo for the delivery infra alone; you still ship product events into it. Hookdeck Mid is ~$200/mo. Sendora bundles the same delivery posture (HMAC-SHA256 signed, exponential-backoff retry, replay, delivery log, SSRF-guarded inbound) into every module's event stream natively. One webhook endpoint subscription captures `auth.user_created`, `auth.device_takeover`, `push.token_invalidated`, `email.bounced`, `support.ticket_created`, `csat.detractor`, `billing.subscription_updated`, `automation.run_completed`, `attribution.install_attributed`, and 40+ more — one signed payload format, one rotating secret, one delivery log. The "integrate this" step in every SaaS evaluation, already done.
