FWIW, the Codidact project has been plugging away at building an OSS replacement for SE:

#23You mean I gotta start thinking on my own? Not sure that will work.
I am using the Stackoverflow Keyboard. How am I supposed to type code now?

A read-only, self-hostable copy of StackOverflow (and its sister sites) is already doable with Kiwix + the content packages they publish.
Content packages: https://wiki.kiwix.org/wiki/Content_in_all_languages
Example of how a site looks like (in this case SuperUser), hosted on my server: https://kiwix.ounapuu.ee/superuser.com_en_all_2021-04/A/inde...
And hosting it really isn't all that difficult: https://ounapuu.ee/posts/2021/12/09/self-hosting-wikipedia/

Stackoverflow's data is cc-by-sa 4.0 licensed and can be found here: https://archive.org/details/stackexchange So nothing is stopping anyone to spin-up multiple instances.
It's much harder to work with the data if you don't have the code. SO is not open source.

#28So what is their stack, or where can I find more about it? A totally custom webserver? Someone commented to this effect the yesterday [1], but I couldn't find much in the way of a good writeup, except this answer from 2009 [2]. 1 https://news.ycombinator.com/item?id=32321726 2 https://stackoverflow.com/questions/676326/how-does-stackove...
Scott Hanselman had an interview with the Stack Overflow Director of Engineering just a few weeks ago. They cover some high-level details there [0]. As I understand it's an .NET Core monolith with a very-large (~1.5 TB RAM) SQL Server backend. [0] https://hanselminutes.com/847/engineering-stack-overflow-wit...
One thing about using SQL databases live in production for everything is that the architecture is amazingly simple, almost always performant, but if something goes wrong, it goes catastrophically wrong.
Amazon for new critical applications prefers NoSQL solutions for this reason since performance is flatter and not dependent on vagaries of the query optimizer.

StackExchange is by no means perfect, but the copyleft content license is a key reason I feel comfortable contributing to the platform. (Which I assume is why they do it.)

#30Finally we can't thanks the spam copies, they assure the vital service of caching the site when it goes down.
