I've discovered that there are many Stack Exchange sites: http://stackoverflow.com, http://apple.stackexchange.com, http://gamedev.stackexchange.com and perhaps others.

What are the differences between these sites, and what is http://stackoverflow.com mainly about?

Where can I find a list of all the Stack sites?

    I don't understand: how do you not know what stackoverflow is about? you've been on the site for three months, and seem to have an idea of what it's for, judging by your questions (this one being the exception)... And if you're still confused, please read the below migration message for more info... – Mac Feb 17 '11 at 0:54

    @Mac : Yes, of course I know what it is about :-) And reading the migration message, being an enthusiast programmers programmer, I'm still confused... – Oliver Feb 17 '11 at 0:58

  • Is there a site where programmers can exchange opinions on tech matters? Stack overflow is supper restrictive - sometimes I'd value hearing a good debate between folks on best practice, best technology etc. without needing a specific coding issue that needs fixing. – user1761806 Nov 25 '18 at 2:36

Stack Exchange is a network of sites, of which Stack Overflow is one. They each use the same software but are generally geared towards certain topics... Stack Overflow being geared towards programming, and others being geared towards other particular topics.

You can either check out the FAQ on each site, or sometimes just looking at the name is enough:


...is a Stack Exchange site geared towards, well, code golfing :)

(Contains the list of sites with a short description of each; answering both questions).


(Added by infoSetu's edit an introductory overview of stackexchange/stackoverflow).


If you're wondering what Stack Exchange is, I suggest clicking the gen-u-winetm Stack Exchange logo in the upper left hand corner of every site.

There are a bunch of links and information there, which should tell you everything you need to know!


You could visit each site's FAQ to see what they are all about. Simply append /faq to each domain and you're there!

Like this: https://meta.stackoverflow.com/faq


Check out https://stackexchange.com/sites There, all the stackexchange websites are listed and will give you a nice overview!
