WiKiss

WiKiss is a lightweight, self‑hostable wiki written in PHP that can be installed and configured in a few minutes. It provides the essential features expected of a wiki, including a simplified markup language, automatic table of contents, version history with diff comparison, password protection, and a built‑in search function. The system generates XHTML 1.0 Transitional output and supports extensibility through plugins for tasks such as table management and RSS feed generation, while allowing custom themes.

The software is distributed under the GNU GPL v2 license, making it free and open source without any subscription requirements. It is a fork of the now‑inactive TigerWiki project and follows the “Keep It Short and Simple” (KISS) principle, aiming for ease of use and minimal setup overhead. Documentation covers installation, configuration, syntax, and usage, and a community mailing list offers support.

Designed for individuals or small teams that need a straightforward wiki for collaborative note‑taking or documentation, WiKiss emphasizes quick deployment, basic functionality, and the ability to extend its capabilities through a plugin architecture.
