An Otter Wiki is a lightweight wiki for collaborative content management. Pages are stored as Markdown files in a Git repository, providing built-in version tracking and a simple, clean editing experience.
Key Features
- Git-backed storage with full changelog, page history, diffs, and revert support
- Markdown editor with highlighting and conveniences (including tables)
- Extended Markdown support (tables, footnotes, alerts, fancy blocks, and Mermaid diagrams)
- File attachments and image pasting/uploading into pages
- User authentication with self-registration and password recovery
- Minimalistic interface with dark-mode support
- Customizable sidebar with menu and/or page index
- Experimental Git HTTP server to clone, pull, and push wiki content
Use Cases
- Team documentation and internal knowledge bases with auditable history
- Personal or small-group notes where Git-based workflows are preferred
- Project wikis that need attachments and easy revision comparison
Limitations and Considerations
- The built-in Git HTTP server is marked experimental and may not fit all production workflows
An Otter Wiki is a solid choice if you want a simple, readable wiki that keeps content in plain files and leverages Git for tracking and recovery. It works well for small teams and projects that value minimal UI and straightforward content management.
