Topic on Project:Support desk

Hi! I would like to make a similar website as "wikipedia.org" i.e. it has all the language versions of Wikipedia and a search bar. I can't find the source code for this website anywhere (even on GitHub) so I thought I'd ask here where could I get the source code for the website? And Google’s source code tool doesn’t help because it doesn’t provide more specific (PHP codes) for security reasons. I would think such files are publicly visible on Wikimedia because you have open source.

Thank you for the answers in advance and thank you for the effort you have seen!

If you're looking to have a website that uses the same backend/interface as Wikipedia, all you need to do is download MediaWiki (whose source code is publicly available) and the associated extensions that Wikipedia uses. Some of your ideas (such as languages) will need some work.

Edit: I misread your comment, see Pppery's reply below (thanks).

The toplevel website https://wikipedia.org is not actually served by MediaWiki. Instead, its PHP source code is at https://github.com/wikimedia/portals
