Hookdeck Outpost vs Webhook Relay

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 Relay receives webhooks, transforms payloads and delivers events to public URLs, private servers, localhost or cloud services such as AWS and GCP. It stores incoming events and retries delivery with exponential backoff for up to 30 days. JavaScript or Lua functions can filter, route and transform payloads. Tunnels expose local servers through encrypted connections described as available in multiple regions and non-expiring. The site lists uses with Stripe, GitHub, Shopify, Jenkins, Bitbucket, AWS, GCP and Azure. Webhook Relay can run on customer infrastructure; its agent is available for Linux, Windows and macOS, as well as in a Docker container. The company says it has SOC 2 Type II certification and describes authenticated agents and encrypted tunnels for reaching internal services. The free plan includes 150 webhooks per month, up to two destinations and one input. Its pricing FAQ says free-plan buckets are temporarily suspended from receiving webhooks when the monthly quota is reached. Basic costs $8.99 per month and includes 5,000 webhooks per month, 10 destinations and eight bidirectional tunnels.
