Answer 1

No more free subdomain support from ngrok.....pls have a error as below

Tunnel session failed: Only paid plans may bind custom subdomains. Failed to bind the custom subdomain 'arvindpattartestfb.ngrok.io' for the account 'arvccccc'. This account is on the 'Free' plan.

Upgrade to a paid plan at: https://dashboard.ngrok.com/billing/plan

UPDATE May 2020

Serveo is up and running again! No installation, no signup!

All you need to do is to run this:

ssh -R <unique subdomain>:80:<your local host>:<your local port> serveo.net

like

ssh -R youruniquesubdomain:80:localhost:8000 serveo.net

UPDATE January 2020

Since there are some issues with Serveo and localtunnel, I want to share with you another free ssh-based self-hosting service: Localhost.run

Unfortunately, it does not provide unique subdomains but it is ssh-based so you do not have to install additional applications. Still waiting for Serveo coming back.

I've found Serveo just now! And it is totally incredible!

UPDATE November 2017

Probably, it is not the best option for you but I started using localtunnel instead of ngrok.

An installation and run flow is very simple:

npm install -g localtunnel
lt --port <your localhost port> --subdomain youruniquesubdomain

Then I can go to my http://youruniquesubdomain.localtunnel.me That's it!

You need to set up auth token. You can find it here https://dashboard.ngrok.com/auth. (W̶o̶r̶k̶s̶ ̶w̶i̶t̶h̶ ̶f̶r̶e̶e̶ ̶v̶e̶r̶s̶i̶o̶n̶,̶ ̶n̶o̶ ̶n̶e̶e̶d̶ ̶t̶o̶ ̶p̶a̶y̶ it's now paid feature, see ngrok pricing).

Then you can use it like this:

ngrok http 80 --subdomain yoursubdomain
