Hi HN! I’m launching Relae (
https://relaehook.com), a webhook relay service that ensures you never lose critical webhook data from services like Stripe, Shopify, or any other provider.
The Problem
I’ve worked at several companies where debugging lost webhooks was a recurring nightmare. You’d discover hours or days later that critical events from Stripe, Shopify, or other providers never made it through. Someone’s deployment killed the server, a bug caused a 500, or the endpoint timed out.
Every time, it meant manual data reconciliation, customer support tickets, and eventually building one-off retry logic. I saw different teams solve this problem from scratch over and over.
Most webhook providers only retry a few times over a short window, then give up. You’re left manually reconciling data or building your own retry infrastructure.
What Relae Does
Relae sits between webhook providers and your app:
1. Automatic retries – Exponential backoff up to 5 attempts
2. Dead letter queue – Failed webhooks don’t disappear; review and manually retry them
3. HMAC signature verification – Security built-in
4. Real-time monitoring – See delivery status, failures, and retry attempts
5. Custom headers – Add authentication or routing metadata
It’s basically the infrastructure you’d build yourself, but as a service.
Why I Built This
After seeing teams at multiple companies solve the same webhook reliability problem from scratch, I realized this is infrastructure that shouldn’t need to be rebuilt every time. I wanted something simple: point your webhooks at Relae, and we handle the reliability guarantees so you don’t have to.
Tech Stack
Backend written in Go, running on DigitalOcean droplets. Focused on low latency and reliability without the complexity of serverless. Free tier includes 10k events/month, which is plenty for most side projects.
What I’m Looking For
Feedback on the product, the pricing, and whether this solves a real problem for you. I’m also curious if there are specific features that would make this more useful (batching, filtering, transformations, etc.).
Free tier available – no credit card required. Would love for you to try it and let me know what you think!
