ngrok - secure introspectable tunnels to localhost ([homepage](https://ngrok.com))
"I want to expose a local server behind a NAT or firewall to the Internet."
What is ngrok?
ngrok is a reverse proxy that creates a secure tunnel from a public endpoint to a locally running web service.
ngrok captures and analyzes all traffic over the tunnel for later inspection and replay.
What can I do with ngrok?
Expose any http service behind a NAT or firewall to the internet on a subdomain of ngrok.com.
Expose any tcp service behind a NAT or firewall to the internet on a random port of ngrok.com.
Inspect all http requests/responses that are transmitted over the tunnel.
Replay any request that was transmitted over the tunnel.
