Tunnel services with request inspectors (lrok, ngrok) capture every request that passes through the tunnel and surface it in a dashboard. You can see exactly what Stripe sent, click to view full body, replay it against your local handler.
Without an inspector, you'd be relying on print debugging in your handler — which doesn't help if the request never reaches your handler (signature failed, body parse error before logging, etc.).
lrok captures the last 100 requests per tunnel in memory. They evict on tunnel close. Never persisted to disk — keeps the privacy footprint small for webhook bodies that often contain PII.
