fasthook - 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?
