Send webhooks in minutes for one-tenth the cost. Outpost is open-source infrastructure that delivers to webhooks, SQS, Pub/Sub, RabbitMQ, Kafka, and more. Multi-tenant, at-least-once delivery, customer portal — self-hosted or managed.
Hey Product Hunt, and thanks to @fmerian for hunting!
We launched Outpost as an open-source project about a year ago to solve a problem we kept seeing: every platform that needs to send webhooks to their customers ends up building the same infrastructure from scratch: retries, tenant isolation, delivery logs, a portal for end users to manage their endpoints. It's a significant engineering investment for something that isn't anyone's core product.
Outpost was our answer to that: open source, self-hostable, and designed to be the last outbound webhook system you need to build.
Outpost doesn't just do webhooks. It supports Event Destinations, too: your customers can receive events via SQS, Pub/Sub, Kafka, RabbitMQ, and other brokers and queues, not just HTTP requests. This is something we've seen Stripe, Shopify, and Twilio all moving toward, and Outpost gives any platform the same capability out of the box.
We also now offer a managed version (Hookdeck Outpost) for teams that don't want to run the infrastructure themselves. It runs the exact same codebase (no proprietary fork). Pricing starts at $10 per million events, which makes it the most affordable managed option available.
Would love to hear from anyone who's currently maintaining a homegrown webhook delivery system. What are the biggest pain points? And if you've tried Outpost, what could we do better?
