Wiki.js
Modern, lightweight and powerful wiki app using Git and Markdown.
Wiki.js provides a self‑hosted wiki platform built on Node.js that stores content in Git repositories and supports Markdown as the primary authoring format. It offers a web interface with live preview, a visual editor for non‑technical users, and direct HTML editing, allowing teams to create and maintain documentation without needing proprietary services.
The software includes an extensible module system that can be enabled or disabled per installation, covering authentication (local, OAuth2, LDAP, SAML, and social providers), user management, search, rendering, and media handling. It works with PostgreSQL, MySQL, MariaDB, MS SQL Server, or SQLite, and can run on a range of hardware from low‑power devices to cloud VMs.
Released under the AGPL‑3.0 license, Wiki.js is open source and free to use, with a focus on performance, customizable themes (light and dark modes), and granular access control. It is intended for developers, technical writers, and organizations that need a flexible, on‑premises knowledge base.
