Share localhost with anyone

Ever wanted to quickly share your localhost server with someone else, without going through the hassle of deploying it somewhere?

You’ll be happy to know that there’s a really simple way to do this. First install the localtunnel gem:

$ gem install localtunnel

Next run your localhost server, for example in Rails, using the default WEBrick server:

$ rails s

Or Python:

$ python - m SimpleHTTPServer 8000

The first time you run localtunnel you’ll need to use one of your public SSH keys:

$ localtunnel -k ~/.ssh/ 8000

You’ll see something like this in your terminal:

➜  project_name git:(develop) localtunnel 8000
   This localtunnel service is brought to you by Twilio.
   Port 8000 is now publicly accessible from ...

Now just share with whoever needs to see your work.

Subsequently you can just use localtunnel <port> to generate a public URL:

$ localtunnel 8000

And that’s it. Install and setup takes less than 5 minutes, and it works beautifully.

Useful tool in many scenarios I imagine, but it's worth noting that while using any server that will let you bind to you can simply set up forwarding rules on your router/firewall and anyone outside your network should be able to reach it. WEBrick does this by default.

If you are on the same network you can just take his IP adress and put it on your .htaccess (Allow from
