Which of the numerous WMD editors are used on Stack Overflow?

When I Google SO and WMD Editor there are several results linking to several different forks. What I've found so far are:

Side note, most of the questions related to this topic, on MSO, date back to 2008-2010.

Some clarification would be great.

I can't claim to be an authority on this subject, but the tag wiki has the following to say.

This editor is open source.

On the server it is MarkdownSharp: https://github.com/balpha/markdownsharp

On the client it is PageDown: https://github.com/StackExchange/pagedown

  • Thanks Chris, I was thinking PageDown as well due to the recent update activity, but would like to be sure. I'm going to hold off on accepting to see if I can get an "official" word. Feb 11 '12 at 1:23
  • @DigitalPrecision Sounds good. For what it's worth, it also looks like Jeff added this information in September 2011. Feb 11 '12 at 1:25

    @DigitalPrecision Not that my word is necessarily any more official than Chris', but PageDown is indeed the official project that's being maintained and used on the Stack Exchange network.

  • Ahhh that's good enough for me then. Thanks for the help guys. Pagedown it is. Feb 11 '12 at 1:35
  • What is MarkdownSharp used for? Pagedown includes the validation and everything you need, no? Dec 30 '14 at 21:44

    It seems the stack exchange github page has changed and pagedown is now on github here: balpha/pagedown Dec 23 '15 at 19:09
  • Both http://code.google.com/p/markdownsharp/ and http://code.google.com/p/pagedown/ are broken now (404) (Google Code shutdown 2016-01-15). Perhaps update? Jun 3 '19 at 9:25
  • @PeterMortensen Nice catch! Just updated it now. Jun 7 '19 at 6:37
