Hookbridge vs Hookdeck Outpost

Hookbridge is a cloud service for software teams that send webhooks to customer endpoints, receive third-party webhooks or hold incoming events for workers to retrieve through an API. Its send API queues a message and returns an ID, so delivery continues outside the application's request path. Outbound retries use exponential backoff and jitter according to a configured schedule for retryable failures. Retained messages can be replayed from the console or API after successful or failed delivery. Security options include outbound HMAC-SHA256 signatures and inbound checks using configured HMAC signatures, static tokens or IP allowlists. Hookbridge says it encrypts data in transit and uses access controls and monitoring; payload and delivery-log retention depends on plan and customer settings, with automatic purging after the configured window. Developers can use an HTTP API and SDK examples for Node.js, Python, Go, Ruby and PHP. Tools include a CLI tunnel, a GitHub Action for CI testing and an account-free browser request inspector.

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.
