/etc/hosts based tiny reverse proxy. You may sometimes run a web application on http://localhost:3000 during development, or sometimes you may configure local port forward on http://localhost:8080 with SSH to access web servers behind firewalls. Hosty loads your /etc/hosts and acts as a reverse proxy to simplify the URLs. It allows you to manage mappings of local server name and port on /etc/hosts.
