Author of MDwiki here. Versioning and editing is indeed intended to be done and handled through git. Pull requests are prefered method for collaboration.
Another way is to place the wiki on a Dropbox shared public folder and share the folder with your collaborators. Hosting can be done through Dropbox as well.
I had the same thought as the parent of your comment, but I really like this way of doing things, well done. Looks really clean and I'd consider using it if I needed a wiki for some project.
Wikis are editable live, usually by anybody; but I cannot see a way to edit any of these projects that use MDwiki. So if that is the case, this isn't a wiki project, and why is it called one?
What.. a "wiki" that isn't shared? (I can see it could be made to have server component, I like the idea of doing all rendering on client-side, why not?!) The rendering is unfortunately glitchy (FF30; sometimes the CSS seems to drop during load/link clicks) and the stack of various libraries used is so deep that it may well be difficult to find the cause? Sorry, that's presumptuous actually, but I sometimes wonder why small projects like this need this many libs:
TiddlyWiki, the original self-contained wiki (and now nearly 10 years old), was (is?) often used for note-taking. All you need is a browser, point it at a file:/// URI and you could save your changes locally.
That's really cool! It reminded me of Ward Cunningham's Smallest Federated Wiki, which is mostly client-side too; although it normally uses sinatra, there's an arduino port and I seem to recall an experimental server implemented using only apache conf hacks too.
If anyone wants a python implementation, I have recently found MarkWiki[0] to be quite excellent. It's simple to use - I deployed it within a small team, all familiar with markdown.
This is similar to what we are building at UserDeck. We call it Guides and it is a knowledge base widget that embeds inline into any page of a website. It is all Javascript and customizable on the client side with layouts and components which have options which let you change things like a sidebar component to the right side instead of the left.
Any team member can collaborate and edit articles live on the site and we are considering adding wiki type functionality if people are interested.
Crawling is an issue. But if you google for mdwiki, first result will be the projects website which IS crawled. I think this is undocumented by google, but they do fetch ajax content. But you can not do professional SEO with frontend-only solutions.
AFAICT, this entirely runs on the client. The server just serves some static web pages. Presumably, if you save the static HTML / js / css files onto your laptop, you could use the wiki when you're offline.
IMHO to be a wiki it would need to manage user editing and version control.
