Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 157 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

Is the Stack Exchange engine available to download for use as a enterprise website?

I think Stack Exchange's engine is very great and could be very cool to use for internal enterprise patterns and practices, like the engine of Wikipedia.

There is a Stack Exchange Enterprise option for internal use only (i.e., not public internet). The pricing makes this feasible for large organizations only. You can email team[at]stackoverflow[dot]com and your inquiry will be routed to the correct place.

The company I work at has an internal implementation, which judging by the oldest question has been running since March 2010. – Ric Apr 4 '13 at 9:37
@AlEverett As of September 2013, this is still an option, correct? – John Bensin Sep 13 '13 at 17:51
@John: As far as I know. I've not seen anything that says different. – Al E. Sep 13 '13 at 17:52
Is there an official link to get information about the Stack Exchange Enterprise? – user1529011 Oct 1 '13 at 8:46

Stack Exchange no longer provides a subscription service nor can we license the software to create 3rd party sites. There is a Stack Exchange Enterprise version available for internal use only (i.e. not public internet), but it is very expensive and meant for very large enterprises only.

The only way to create a Stack Exchange site is through our community-driven process we call Area 51. It's a service where groups of experts come together to build new Q&A sites that work just like Stack Overflow. You can read more about that process here:

Does the enterprise edition use the latest engine and get all the improvements as they happen or is it the old white label 1.0 version? – Lorem Ipsum Sep 19 '13 at 15:49
The code was forked off of the 1.0 version long ago. I imagine bug fixes and such are supported, but it is not being updated alongside the current Stack Exchange Network codebase. – Robert Cartaino Sep 19 '13 at 15:54
How expensive is 'very expensive', or at least where do I go to get that detail? Thanks! – Griffith Sep 30 '13 at 17:14
@Griffith, Well we can make a guess. Probably between 6 digits to 9 digits ;) However companies would rather use OSQA because when there are bugs, they could simply send engineers to the open-source team to fix it directly. – Pacerier Jan 10 '15 at 8:43

Is the Stack Exchange engine available to download for use as a enterprise website?

Not for download, but there is a Enterprise version that can be purchased for internal use only. But this is only meant for very large organizations.

However, there is a number of clones available, some of which have become pretty mature.

Do you have any new information? This contradicts the accepted answer, which says that it is available, but very expensive. – CodesInChaos Mar 12 '12 at 10:36
@Code there is an answer from Michael Pryor here that says that, but was deleted May 25 last year. I assume that means it is no longer available. – Pëkka Mar 12 '12 at 10:51
The most recent edit to the accepted answer was by Michael Pryor, but it's older than May 25 2011. – CodesInChaos Mar 12 '12 at 10:56
The current accepted answer is still correct! – Michael Pryor Apr 30 '12 at 20:29
any good SO clone open source? – Kiquenet Apr 26 '13 at 8:00
@Kiquenet have you looked at the list linked above? – Pëkka Apr 26 '13 at 8:03
