How I Built a Webhook Debugger with Hono, React 19, and SQLite

Every developer who's integrated webhooks knows the pain. You configure an endpoint, wait for a provider to fire a test event, check your server logs, realize the payload format isn't what you expected, reconfigure, and wait again. Repeat until you lose the will to live. I built HookRelay to fix this. It gives you a unique URL that captures any incoming HTTP request and displays it in a real-time dashboard — headers, body, timing, everything. The Problem Webhook debugging is uniquely frustrating because: You can't control when they fire. Unlike API calls you initiate, webhooks arrive on their schedule. Payloads vary wildly. Every provider has a different format, and documentation is often incomplete. Failed deliveries disappear. Most providers retry a few times, then give up. If you weren't logging, that payload is gone. Local development is painful. You need ngrok or similar tunneling just to receive webhooks on localhost.
