Hookdeck vs Hookdeck Outpost

Hookdeck provides infrastructure for receiving, managing, and delivering webhooks and other external events. Its Event Gateway ingests and queues incoming events, then can transform and deliver them with controls for signature checks, conditional routing, retries, logs, alerts, tracing, and replay. Outpost adds event delivery for APIs, SaaS, and PaaS products, with managed and self-hosted options. Listed destinations include webhooks, Amazon SQS, RabbitMQ, Google Pub/Sub, AWS EventBridge, Apache Kafka, and the Event Gateway. The CLI forwards webhook events to a local web server and can replay or inspect forwarded data. The Developer plan is free, with up to 10,000 events and three-day retention; the dashboard locks after that event limit until upgrade or the next billing period. Paid plans start at $39 a month. A 14-day trial for inviting team members is available, subject to Developer plan usage limits.

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.
