ngrok — Expose Your Localhost to the World in One Command

ngrok creates secure tunnels from the internet to your local development machine. Run ngrok http 3000 and get a public URL that forwards to your localhost — essential for testing webhooks, sharing work-in-progress, and developing with external services that need a callback URL.

Every Developer Needs This

Stripe webhooks need a public URL. OAuth callbacks need a redirect URL. Mobile apps need an API endpoint. Sharing a prototype with your team needs a link. Without ngrok, you either deploy to staging for every test or configure complex port forwarding. With ngrok, one command solves all of these.

Beyond Simple Tunneling

ngrok is not just a tunnel — it is a programmable ingress platform. Request inspection lets you replay webhooks during development. IP restrictions control who can access your tunnel. OAuth integration adds authentication to any tunnel. Traffic policies let you route, transform, and rate-limit requests at the edge.

ngrok for Webhooks

The webhook debugging workflow is where ngrok shines. Start a tunnel, paste the URL into Stripe/GitHub/Twilio, and watch incoming webhooks in the ngrok dashboard. See headers, body, and response. Replay any webhook to test error handling. No more console.log debugging.

ngrok vs Cloudflare Tunnel

Cloudflare Tunnel is free and designed for exposing production services. ngrok is designed for development with better webhook inspection, replay, and debugging. Use Cloudflare Tunnel for production. Use ngrok for development.

ngrok vs localtunnel

localtunnel is a free, simpler alternative. ngrok is more reliable, faster, and offers critical features like request inspection, custom domains, and authentication that localtunnel lacks.
