Reliable webhook delivery with replay, retries, and debuging
Hey Product Hunt 👋
FastHook started from a problem I kept seeing in webhook-based systems:
A service returns 200 OK, but the actual event processing silently fails afterwards.
Missing Stripe events, duplicate deliveries, failed retries, broken integrations, webhook payloads lost during deploys — teams end up building custom retry/replay/debugging infrastructure over and over again.
FastHook was built to make webhook handling more reliable without needing to build all that infrastructure internally.
It provides:
* webhook buffering
* retries
* replay
* routing
* transformations
* inspection/debugging
* localhost tunneling for development
One thing that surprised me while building this: many developers still test critical webhook flows directly in production because local webhook development is painful. That became a big focus area too.
Would genuinely love feedback from people building:
* APIs
* SaaS products
* automations
* AI workflows
* event-driven systems
Especially interested in hearing:
What’s been your biggest webhook pain point so far?
