FAQs

Can't find what you're looking for? Talk to us, and we'll walk you through it.

What is Outpost?

Outpost is open-source webhook delivery infrastructure that lets you send events to your users' preferred destinations including webhooks, SQS, RabbitMQ, Pub/Sub, EventBridge, Kafka, and more.

What's the difference between Managed and Self-hosted?

Managed Outpost is hosted and operated by Hookdeck with a serverless, usage-based pricing model. Self-hosted Outpost uses the same open-source codebase but you deploy and manage it in your own infrastructure.

Is Outpost really open source?

Yes. Outpost is licensed under Apache 2.0. There are no proprietary versions or private forks – the same exact codebase is used for both managed and self-hosted deployments.

How do I get started with self-hosted Outpost?

You can deploy Outpost using Docker or Kubernetes on any cloud provider including AWS, Azure, GCP, Railway, or Fly.io. Check out the GitHub repository and quickstart guides to get started.

What event destinations does Outpost support?

Outpost supports delivering events to webhooks (HTTP endpoints), Amazon SQS, RabbitMQ, Google Pub/Sub, AWS EventBridge, Apache Kafka, and the Hookdeck Event Gateway.

Can I migrate from another webhook provider?

Yes. Outpost is designed to be backward compatible, allowing you to maintain existing signatures, secrets, and retry logic without user-facing changes.

How is event usage billed?

Usage is prorated in chunks of 10,000 events. At $10 per million events, each 10,000-event chunk costs $0.10, so if you use 10,001 events you are billed for two chunks ($0.20).

What counts as an "Event" for pricing?

An event is counted when it is delivered to a destination. If a tenant has two destinations and one published event is delivered to both, that counts as two events. Retries are not charged.
