Outpost

Outpost is a serverless service for outbound webhooks and event delivery that eliminates the complexity of traditional webhook infrastructure. Whether you choose the managed service or self-hosted deployment, you get reliable event delivery without unnecessary overhead.

Key capabilities include:

• At-least-once delivery guarantee - Messages are never lost with built-in retry logic
• Multiple destination support - Send to webhooks, AWS SQS, RabbitMQ, Pub/Sub, EventBridge, Kafka, and more
• Topic-based subscriptions - Publish and subscribe model for easy integration
• Flexible deployment - Available as managed service ($10 per million events) or free open-source self-hosted option
• Developer-friendly portal - Monitor metrics, manage destinations, debug events, and configure alerts
• Security built-in - Idempotency headers, request signatures, timestamp validation, and signature rotation
• OpenTelemetry support - Standardized traces, metrics, and logs for observability
• Multi-tenant ready - Run multiple tenants on a single deployment

Outpost moves beyond traditional webhooks by offering event destinations - a more interoperable and secure approach designed for modern platforms. The infrastructure is simple to deploy, maintains backwards compatibility with existing webhook implementations, and scales cost-effectively from startup to enterprise volumes. Teams use Outpost to centralize event delivery, reduce infrastructure complexity, and give customers flexible ways to consume their data.
