We are using Confluence for public and internal wiki, it has a bad search and really slow, but no matter how much everyone hates it, the market does not provide worthy alternatives. When choosing 3 years ago, we used the following criteria: * WYSIWYG editor. Any user must have a minimum effort to write documentation * Flexible access permissions to various parts of the documentation. Public documentation is open to anonymous users, the internal one is divided into many sections with access for certain groups * Multilingual support. Not out of the box, but possible with plugins * Multilingual pdf export. In some markets, some customers prefer to have exported manuals * The ability to inherit articles. We need to be able to make edits once, instead of duplicating the same articles * Have a relatively modern appearance. Wiki engines are familiar to many because the whole world uses Wikipedia, but this does not make them more pleasing to the eyes, if I can say so 3 years have passed, I periodically look at alternatives, so far only wiki.js seems like a good solution but it’s not even close yet.
