Use ngrok. Go to ngrok.com and download the archive

Ore Adeleye Is there any way to make the generated url permanent?

R_C You can host your website for free with 000webhost.com or x10hosting.com

Ore Adeleye What is the difference in using ngrok and 000webhost.com/x10hosting.com

R_C ngrok does not host your site. It only use tunnels to make your site publicly accessible. 000webhost and x10hosting hosts your site files on their servers for free by creating a dedicated sub domain for you. With ngrok your files are still on your computer filesystem.

Oh okay Thank you Ore Adeleye
