Do you know an app to make easily virtual hosts on mac (I want myapp.local instead of localhost:9000) without playing around with apache?
Should be accessible inside of your browser at myapp.local:9000
Also, ngrok as mentioned by Swizec is cool but it generates its own url and not myapp.local.
ngrok is cool for testing on multiple devices no matter where they are. setup ngrok and forward the link to my brother on Windows for IE and my other one running Linux for whatever otherside of the planet. Pretty dope.
I also use the ghost Rubygem to manage my /etc/hosts file. https://github.com/bjeanes/ghost
