Is Stack Overflow open source? If so - where can I get the source code?

If not - I see some people using it: http://answers.unity3d.com how did they get it?

You can get your own "Stack Overflow" from http://stackexchange.com - you can be up and running for free to give the platform a spin.

  • Umm.. is there no free options? I mean how did you guys get a hold of it? Mar 18, 2010 at 1:44
  • Stack Overflow was the original site, and they developed it. There is no free option available.

  • @drozzy: @JeffAtwood (creator and co-founder of Stack Overflow) did pose the question of open-sourcing a while back - meta.stackoverflow.com/questions/3086/…

  • Wow, it seems that question was beaten to death already... well I guess the only way for me to get something like this is to make it myself. Thanks! Mar 18, 2010 at 2:02

  • @drozzy: you can also take a look at some open source alternatives listed here: meta.stackexchange.com/questions/2267/stack-exchange-clones Jul 15, 2015 at 1:34
