Tunnelling services

If you have some project on your local machine (desktop or laptop), but you have no publish IP address, domain name and you need someone to visit your job. How to?
Tunnelling services can help you, serveo and ngrok (pronounce it en-grok) is a good solutions, even you are under firewall or NAT. It's also support HTTPS too!
serveo

No need any install, just open terminal then use command
ssh -R 80:localhost:3000 serveo.net
Forwarding HTTP traffic from https://patrickz.serveo.net
It will forward HTTP traffic from domain patrickz.serveo.net to your server which run on port 3000. So you just only send https://patrickz.serveo.net to your visitor. The visitor should see your server.
However, if you will use serveo with facebook apps. Seem it not work. I recommend to try ngrok
.
More information, check http://serveo.net/
ngrok

After installed and register to use the service (Don't worry, just take a few minute). just use command ngrok http 80
. You should see the result like this
