Otter Wiki

Otter Wiki is an open-source application for collaborative content management. It uses a Git repository to store content and track all changes, ensuring a complete history of page revisions. The software is built with Python and the Flask microframework, utilizing the halfmoon CSS framework for its interface and CodeMirror for its text editor. By leveraging Git as the backend, the system provides a reliable way to manage versioning and content integrity without relying on a traditional database for page storage.

The application supports extended Markdown, allowing users to create tables, footnotes, alerts, and mermaid diagrams. Key features include a customizable sidebar that can be configured with a specific menu or a page index, user authentication to manage access, and the ability to add page attachments for supplementary data. It includes a dark mode for the user interface and provides a full changelog for all wiki entries to monitor evolution over time. An experimental Git HTTP server is also available, which allows users to clone, pull, and push wiki content directly using standard Git tools.

Installation is primarily handled via docker-compose, though the software can be configured with web servers such as nginx, apache, or caddy for internet access. The first registered account is granted administrator privileges to manage global settings and user permissions. The application is designed to be lightweight and easy to deploy in containerized environments. Otter Wiki is positioned as a tool for users who prefer a Git-backed knowledge base with a clean interface and a focus on Markdown for content creation.
