All of us are aware of Wikipedia, an ocean of information. It is basically a wiki, which allows easy creation and and editing of all the pages by all the visitors which either can submit as normal visitors or they just need to create an account and edit the pages or create some content. Wikis can be edited by using a normal Web Browser, without any extra plugin or add-on or extension. Some sites provide WYSIWYG editor to edit their wiki while others ask us to learn a simple markup language, that depends on what Wiki Software is used by that site to create the Wiki and what are their administrative settings.

So, now a days, many sites are as well creating their own wiki, either for their internal knowledge management, or note taking or making a collaborative knowledge portal or to make a community website. Do you also wish to let your visitors easily contribute to your website and add their content on a particular topic so as to enhance the value of your web pages with their personal thoughts, learning and experiences? Wiki is a best solution for such kind of platform creation. There are many cool Wiki Software platforms or Wiki engines available, which are open source and free. I am listing below 10 most popular and widely used Wiki engines, which have a lots of administrative control options so that they can create a easily manageable functional wiki in no time. So you decide which is the best wiki software for you to create your fully operational wiki and do let us know which wiki software platform you think is best suitable for you and why thru our comments section.

9. Zoho Wiki

If you do not want to download and maintain a wiki engine on your web server, then Zoho Wiki is a beautiful online wiki solution from Zoho, and it is free with a limit of 2 wikis per user. Zoho Wiki is an intuitive, user friendly tool that allows you to build a website of your dreams complete with pictures and multi-media contents.

Again, I must say, it is a very beautiful wiki interface, with inbuilt WYSIWYG interface, collaboration tools and fine-grained access privileges to create groups, set wiki or page level permissions. It has a feature to keep up-to-date information through instant RSS feeds, subscribe to watch pages and follow thread of discussions.

This is also a free online platform which would help you create your a beautiful wiki on their own server. Wikia is having more features than zoho in some headings, I must say. The most important thing is, you can embed your ad codes in a wiki created on Wikia, which is not available on Zoho. It is having an attractive interface and web page looks. It offers categories, which zoho does not.
