Hookdeck Outpost vs Webhook Management

Hookdeck Outpost is outbound webhook infrastructure for platforms sending events to destinations selected by their users. Hookdeck offers a managed service, while the open-source version can run on infrastructure you manage. That version is licensed under Apache-2.0, written in Go, and distributed as a binary and Docker container. Outpost supports event topics, topic-based subscriptions, destination filters based on event content, tenant isolation, and fan-out to multiple destinations. Destinations include webhooks, AWS services, Google Pub/Sub, Azure Service Bus, RabbitMQ, Kafka, Cloudflare Queues, and Hookdeck Event Gateway. Delivery is at least once, so consumers should deduplicate events by event ID. Failed deliveries retry automatically with exponential backoff by default, with customizable schedules and manual retries through the Retry API, tenant portal, or Admin UI. It supports webhook signatures, Standard Webhooks compatibility, secret rotation, destination-failure alerts, optional automatic disabling of failed destinations, and OpenTelemetry metrics. Self-hosting is always free; managed Starter is $10 a month, and Growth is $499 a month.

Webhook Management sends and tracks webhooks through a dashboard and REST API. Users can register and test endpoints, route selected event types, inspect deliveries, and replay historical events. Failed deliveries are retried with configurable exponential backoff, and events remain stored until delivery succeeds or they are manually cancelled. Each webhook is signed with HMAC-SHA256 so recipients can verify authenticity and detect tampering. The dashboard tracks delivery success, latency, and endpoint health, with failure alerts; consistently failing endpoints are disabled automatically. The product page states a 99.99% delivery rate and average latency under 200 ms. The API covers endpoint creation, sending and listing events, retrying events, and checking endpoint health. The maker describes use in SaaS integrations, payment events, event-driven architectures, and partner notifications. Starter is free for up to 10,000 API requests per month and includes seven-day log retention. Pro is billed monthly for usage, with unlimited API requests and Webhook Management listed at €0.0001/delivery. The Webhook Management plan is listed at free, starting at $0.0001 per event, with up to five retry attempts included; additional retries are charged. The product lists 30-day retention.
