The design of SO/SU/SF is very clean and easy to use, I want to have a similar one to host the Q/A service in my local company, is it open source? or does stack overflow service inc. have the Q/A hosting service?

  • If you have SharePoint 2013 running internally there is an OOTB Q&A plugin that can be turned on.

I'm sorry to say that no, you can't self host. And it is not open source.

But there are open source clones exist. One of the example is cnprog. You can access the source here and here.

After you have the source, you can do anything you want.

Check out Area 51.

    One caveat: you cannot use Area 51 to create a private site. Even if you can get enough users, your site will be open for all on the Internet to see. Also, you will have a something.stackexchange.com URL in the beta and a TLD TBD in the potential "real" version, never a help.yourcompany.com URL.
