For a customer-facing webhook API, choose the recovery contract before comparing the monthly event allowance. An automatic retry window, a retained payload and a manual replay capability are three different promises. A service can retain an event after its scheduled attempts have ended, or stop delivering a queued event when retention expires. Your incident response needs to cover both boundaries.
Compare recovery, retention and admission separately
| Platform | Recovery control examined | Buying implication |
|---|---|---|
| Svix | Published schedule and failed/missing-message recovery | Plan an explicit operator recovery after automatic exhaustion |
| Hookdeck | Configurable retry rules with retention-limited event access | Check destination rate and retained backlog together |
| Convoy | Subscription delivery modes and retry configuration | Verify the selected mode, release and throughput package |
| Hook0 | Escalating retries bounded by attempts and retry window | Distinguish automatic retry budget from daily ingestion quota |
| Webhook Relay | Durable retries and separate outbound recovery operations | Confirm the exact product path and recovery scope |
Svix
Svix’s retry guide publishes the sequence of delays, treats a timely 2xx as success, and documents failed-message recovery as well as replay of messages never attempted. It fits a product team that wants a defined outgoing webhook contract and a consumer portal. Plan manual recovery for outages that outlast automatic retries.
The pricing page distinguishes a base subscription and usage; retries and filtered messages are not equivalent to new billable webhook deliveries. Check retained message history and any advanced-destination entitlement in the proposed plan.
Hookdeck
Hookdeck’s retry documentation describes configurable linear and exponential policies and response-driven retry scheduling. Its event lifecycle documentation also says events older than retention are removed from the queue. A long retry policy therefore needs a compatible retention window; it cannot recover data that the selected contract no longer makes available.
Hookdeck’s event pricing includes retries, while a single inbound request can create multiple delivered events through fan-out. A destination throughput ceiling can delay the drain of a recovered backlog. Choose a retention period and delivery capacity that can accommodate the expected backlog.
Convoy
Convoy’s current changelog distinguishes at-least-once delivery from an at-most-once mode that treats an HTTP response as final while still retrying some no-response failures. Read that product-specific definition before translating the label into application assumptions. A configuration designed to avoid repeated HTTP responses may be unsuitable when a receiver temporarily returns 503.
Its pricing page separates self-hosted Community, licensed self-hosted features and Cloud, and describes fixed throughput packages. The visible self-hosted offer is not an all-in managed-cloud quote. Confirm the release and subscription settings in the proposed deployment.
Hook0
The retry explanation documents an escalating base schedule, positive jitter and separate attempt/window limits. That makes Hook0 useful to examine when the team needs a documented long recovery horizon and can design operations around explicit bounds.
Hook0’s billing guide applies daily event quotas: the free plan rejects excess new events, while documented paid plans bill overage. An ingestion rejection happens before successful admission and is not repaired by the delivery retry schedule. Retain the original producer event and retry admission safely; do not equate free retries with unlimited ingestion.
Webhook Relay
Durable webhook forwarding offers selectable recovery schedules and an explicit deadline. The outbound operations guide separately covers retrying a delivery, recovering exhausted deliveries and replaying missed ones. Confirm which path you are purchasing and implementing; inbound forwarding, private-agent delivery and a customer-facing outbound API are related but distinct workflows.
The plan table includes delivery quotas and operational feature boundaries. Check which recovery controls the intended plan and product path expose, including the quota unit, retention and treatment of retries.
Choose an incident response you can actually operate
For an outgoing product API with customer-operated recovery, examine Svix’s consumer portal first. For routing and transformation around existing integrations, examine Hookdeck’s connection/event model and retention together. Convoy adds a self-hosted gateway option; Hook0 makes a long bounded retry schedule and daily admission contract explicit; Webhook Relay is particularly relevant when private-agent forwarding is part of the requirement. These are conditional shortlists, not an uptime ranking. Verify the exact product path and plan before committing.
If consumers own their recovery, a portal and stable event identity matter. If your team owns recovery, alerts, retained history and a documented replay procedure matter. If the backlog is rate limited, allow enough retained history for it to drain before events expire. Automatic delivery is only one part of that contract. For the work performed after receipt, see our background-job platform comparison; expose recovery status through an appropriate status-page workflow.
