I built a web-based GUI, and I used localhost/its_name to view and develop it. I need to publish it to someone to be able to view it. Is this possible through Github? The GUI contains multiple .php files that call each other when tabs are pressed. (I used atom io text editor to make this project (not sure if that helps))
If you want your project to be viewed by others but don't want to spend money or pay for a domain name, etc. Then you can use Heroku for it. It is a very good hosting service for projects and it can be very helpful if you don't have time and you want your project to be up right now.
Even I have one of my projects hosted right now on Heroku: spend-elons-money
With the Heroku CLI, you can easily host your project from your terminal or command prompt! I hope this is something you were looking for. If not, please let me know!
