Hookdeck Outpost

What Hookdeck Outpost is

Hookdeck Outpost is outbound webhook infrastructure for platforms that send events to destinations their users choose. Hookdeck offers a managed service, and the Apache-2.0-licensed open-source version can be deployed on infrastructure you manage. The software is written in Go and distributed as a binary and Docker container. It supports topics, topic-based subscriptions, filters based on event content, isolated tenants, and sending an event to multiple destinations. Destinations include webhooks, AWS SQS, EventBridge, Kinesis and S3, Google Pub/Sub, Azure Service Bus, RabbitMQ, Kafka, Cloudflare Queues, and Hookdeck Event Gateway.

Outpost provides at-least-once delivery, so consumers should deduplicate events by event ID. Failed deliveries retry automatically with exponential backoff by default, and retry schedules can be customized. Teams can also retry failed attempts through the Retry API, tenant portal, or Admin UI. Security features include webhook signatures, Standard Webhooks compatibility, and secret rotation. Monitoring includes alerts for failing destinations, optional automatic disabling of failed destinations, and OpenTelemetry metrics. SDK quickstarts are available for JavaScript, TypeScript, Python, and Go. The self-hosted plan is always free; managed plans start with Starter at $10 per month, with usage charges described separately.

Who it suits

Outpost suits platforms that need to deliver events to destinations chosen by their users, including systems that serve multiple isolated tenants. It can fit teams that want managed delivery or prefer to deploy the open-source version themselves, with SDK quickstarts for JavaScript, TypeScript, Python, and Go.

Limits

Self-hosted is always free and includes community support. Starter is $10 per month, with the first 50,000 events free, then $10 per million events; it includes 7-day retention. Growth starts at $499 per month and includes 50,000 events, with additional usage at $10 per million; it includes 30-day retention. Delivered destination events count toward usage, retries are not charged, and usage is prorated in 10,000-event chunks.

Verdict

Choose Outpost if your platform needs to route events to user-selected destinations, manage retries, and isolate tenants. The self-hosted plan offers an always-free, open-source route, while managed Starter is listed at $10 per month plus event usage. Teams needing longer retention, an uptime SLA, or listed compliance features may prefer Growth, which starts at $499 per month plus event usage.
