Comparison
Relin vs Hookdeck
Hookdeck is a great webhook gateway — routing, retries, transforms. Relin does that too, and adds the thing Hookdeck doesn't: detecting missing events and alerting you before your customers notice.

Where Hookdeck wins
Full code transforms
Hookdeck lets you run arbitrary JavaScript on payloads in-flight. Relin supports JSON body-path transforms but not full code execution. If you need complex payload reshaping, Hookdeck has the edge.
CLI and local tunneling
Hookdeck has a CLI that tunnels webhooks to your local dev environment. Relin doesn't have this yet. For local debugging, Hookdeck or ngrok are better options today.
Enterprise compliance
Hookdeck has SSO, RBAC, DPAs, and SOC 2 packaging. Relin authenticates through GitHub and doesn't yet have formal compliance documentation. If you need those today, Hookdeck is more mature.
Where Relin wins
Missing event detection
Hookdeck tells you what was delivered. Relin tells you what was never delivered and never retried. Lifecycle rules, sequence checks, and vendor API reconciliation catch the gaps that retries can't fix.
Vendor-aware monitoring
Relin understands Stripe invoice lifecycles, Shopify order sequences, Twilio terminal states, and SendGrid engagement ordering. Generic gateways treat all payloads the same.
Half the price, with a free tier
Relin Team is $19/mo. The free tier includes 50k events per month, gap detection, replay, and alerts — not a stripped-down trial.
Already on Hookdeck? Relin works alongside it.
Point your vendor webhooks at Relin for monitoring and gap detection. Keep Hookdeck for transforms. Or switch entirely — Relin handles delivery too.
