Introspected tunnels to localhost
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.
ngrok 2.x is the successor to 1.x and the focus of all current development effort. Its source code is not available.
NOTE This repository contains the code for ngrok 1.x.
ngrok 1.x is no longer developed, supported or maintained by its author, except to ensure that the project continues to compile. The contribution policy has the following guidelines:
ngrok.com ran a pay-what-you-want hosted service of 1.x from early 2013 until April 7, 2016. Afterwards, it only runs 2.x service.
DO NOT RUN THIS VERSION OF NGROK (1.X) IN PRODUCTION. Both the client and server are known to have serious reliability issues including memory and file descriptor leaks as well as crashes. There is also no HA story as the server is a SPOF. You are advised to run 2.0 for any production quality system.
