Native localhost webhook debugging without ngrok/tunnels ⚡

Hey Makers & Devs,

When building Web3 infrastructure or apps, testing webhooks locally usually breaks the flow.

You find yourself setting up third-party tunnels (ngrok, cloudflared), copying temp URLs into dashboards, and constantly restarting everything when sessions expire.

To eliminate this friction in Quasar, we just added native Local Dev Relay:

👉 Register your endpoint directly as `http://localhost:3000/api/webhooks/quasar`

👉 Drop your secret into `.env.local`

👉 Run: `npx @tuwaio/quasar-sdk listen`

Zero tunnels. Zero third-party proxies. Zero config.

Under the hood, Quasar Cloud routes events through Redis Pub/Sub directly to an authenticated SSE stream over TLS. The local CLI receives them and dispatches to your localhost server with valid HMAC-SHA256 signatures — keeping your local environment isolated with zero SSRF attack vectors.

How are you currently solving the local webhook debugging hassle in your stack?
