Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

Listed here are clones of the Stack Exchange sites model.

What's the actual purpose for this question? – Lipis Jun 21 '12 at 14:41
@Lipis some companies want to implement their own branded version of this software on their own sites to supplement their support and/or knowledge base and provide a place where their customers can interact with them in a way similar to this network. All the alternatives I've investigated pretty much suck in comparison. – Aaron Bertrand Jul 12 '12 at 13:15
Is there any white paper that explains how to build a Q&A site like SO? – morpheus Apr 4 '14 at 23:17
Isn't StackExchange itself a clone of other Q&A sites? Q&A sites with reputation points for good answers have been around for years - I joined Perlmonks back in the year 2000 (it's still going strong). I see SE as a fairly recent arrival. – A E Nov 19 '14 at 10:08
Some companies want to host their own, internal, private Q&A sites. – lambmj Jun 26 '15 at 23:27
“666 Stack Exchange clones” → Nobody is allowed to vote on this anymore, right? – SevenSidedDie Dec 28 '15 at 3:35

actually it is based on askbot, as their web site mentioned: ( – Tomofumi Jun 13 '14 at 4:12

Biostar has several scientific sites going with it.

Apparently OpenStack has its own Ask OpenStack.

(I am not sure if this is based on AskBot or not, and if so, whether it deserves its own entry or not.)

The Answers module, available for Drupal version 7, can be used as a plugin to add a Question & Answer section to any Drupal 7 based website. Some more details about it, from its project page:

... enables the implementation of a Question & Answer system in a Drupal site. Users can post questions and other users can answer them. To see it at work (based on the most recent 7.x-4.x-dev version).

Head over to its Demo site and have a look at the example Questions and/or Answers there.

These modules related to the Answers module are enabled in this demo site:

  • The "core" Answers module, which enables the content types "Question", and "Answer" (whereas Answers are displayed below the Question they relate to).
  • The Answers Theme sub-module, which transforms the (rather boring) vanilla display of a Question (and its related Answers below it), into a way more attractive look-and-feel. Such as the orange bubble that is added around the question (to better highlight it).
  • The Answers Best Answer sub-module, which allows for marking any of the answers to a specific question as the best (accepted) answer (to display the blue checkmarks to the left of each answer, and which is replaced by a green checkmark when an answer is marked as the best answer).

And there are more interesting features that are available (and enabled in this site), such as:

  • The Answers Notification sub-module to allow logged in users to subscribe to selected questions, so that they receive notifications (using the Message Stack) when Questions receive Answers.
  • The Answers Voting sub-module to implement a system to upvote or downvote either Questions and/or Answers (which uses the Rate module).
  • The Answers Userpoints sub-module to increase or decrease "reputation points" (which uses the Userpoints module) on events such as up- or down-voting on a question or answer, or marking an Answer as the "Best Answer".

For an interesting video tutorial about this module (still using the old 7.x-3.x version), refer to Creating a question and answer website in Drupal.

Disclosure: I'm a (co-) maintainer of this module.
