About An Otter Wiki

An Otter Wiki is a minimalistic, open-source wiki application that stores pages as Markdown files in a Git repository, giving every page a full changelog and history. It offers a clean editor with extended Markdown support for tables, formulas, diagrams, and embedded media, file attachments, dark mode, and user authentication with self-registration. Small teams and individuals use it, usually via Docker, for documentation and knowledge bases they fully control.
