I am trying to make a website similar to this and I'd like to know how this website was made. The website is also run on desktop and has a mobile app too so there's no HTML or anything in the back end.
Any ideas?
as mentioned you can use https://www.wappalyzer.com/ or http://builtwith.com to know the technologies used, further more you can view the webpage source or use the inspect element tool to have a better idea of what is going on. and ofcourse there is HTML used in that page whether it was automatically generated or manually
