Otter Wiki

The software provides a collaborative wiki built on Python, Flask, and a Git‑backed storage layer, using Markdown as the authoring format. Pages can be edited with a CodeMirror‑based editor that highlights Markdown syntax, supports tables, footnotes, alerts, and mermaid diagrams, and allows file attachments or direct image pastes. A minimalistic interface includes dark‑mode, a customizable sidebar that can show a menu or page index, and full changelog and history for each page.

User management includes authentication with self‑registration and password recovery, while the underlying Git repository records every change, enabling revision comparison and rollback. Experimental features add a Git HTTP server for cloning, pulling, and pushing wiki content, as well as extended Markdown widgets such as DataTable and ImageFrame.

The project is self‑hostable, distributed under the MIT license, and intended for users who want a lightweight, open‑source wiki that can be deployed via Docker‑Compose or similar tools without subscription fees. It targets teams or individuals needing a simple markdown‑driven knowledge base with version control.
