ngrok vs ShutIt: What are the differences?
ngrok: Securely expose a local web server to the internet and capture all traffic for detailed inspection and replay. ngrok is a reverse proxy that creates a secure tunnel between from a public endpoint to a locally running web service. ngrok captures and analyzes all traffic over the tunnel for later inspection and replay; ShutIt: Automation tool that models a user's actions on a terminal. It can automate any process that can be run by a human on the command line with little effort. It was originally written to manage complex Docker builds, but is a now general-purpose automation tool that supports bash, Docker, Vagrant, ssh and arbitrary build contexts.
ngrok and ShutIt can be primarily classified as "localhost" tools.
ngrok and ShutIt are both open source tools. It seems that ngrok with 16.5K GitHub stars and 2.87K forks on GitHub has more adoption than ShutIt with 1.99K GitHub stars and 121 GitHub forks.
