WiKiss

WiKiss is a flat-file wiki system that stores its content in simple text files rather than a database. It runs on PHP and aims to be minimal and straightforward, making it ideal for small teams or personal projects that need a no-fuss wiki. The setup process is quick, just drop the files on a server and start editing pages.

Key features include page versioning, a search function, and support for basic formatting through a simple markup language. WiKiss does not require MySQL or any other database engine, which keeps system requirements low. It works on any platform that supports PHP, including Linux and Windows servers. The project is hosted on TuxFamily, a nonprofit hosting service for free software projects.

The target audience is users who want a self-contained wiki for documentation, notes, or knowledge bases without overhead. WiKiss is released under the GNU General Public License (GPL), so it is free to use and modify. It has not seen recent releases but remains functional for basic use cases.
