"Demo your latest code ngrok creates a tunnel from the public internet (http://subdomain.ngrok.com) to a port on your local machine. You can give this URL to anyone to allow them to try out a web site you're developing without doing any deployment. Understand HTTP services ngrok captures all traffic through the tunnel. It displays information about the HTTP traffic for your inspection. Raw request/response bytes, parsed headers and form data, JSON/XML syntax checking and more are included. Replay Requests Developing services which consume webhooks can be challenging if the hooks are labor-intensive to generate. Use ngrok's replay request feature to iterate quickly on a new feature without switching contexts to generate new requests." #tunnel #npm #open_source #nodejs #javascript #ssh #web_servers #freemium #unique_features #dev #proxies #local_tunnel #ruby #SaaS #okay_preferred #pricey_ish #pub
