ngrok is a globally distributed, secure reverse proxy and tunneling service that exposes applications running on local machines behind NATs or firewalls to the public internet. It simplifies remote debugging, webhooks integration, and secure ingress by wrapping reverse proxy, firewall traversal, API gateway, and load-balancing functionality into a single tool. ngrok is a globally distributed reverse proxy that secures, protects and accelerates your applications and network services, no matter where you run them. You can think of ngrok as the front door to your applications. ngrok combines your reverse proxy, firewall, API gateway, and global load balancing into one. ngrok can capture and analyze all traffic to your web service for later inspection and replay.
