Wiki.js is an open-source wiki platform, a self-hosted tool for creating and managing internal documentation, knowledge bases, and collaborative notes. Think of it as a modern, self-run alternative to services like Confluence or Notion, but one you install and control on your own server. It's built on Node.js (a JavaScript runtime environment) and uses a Vue-based frontend, making it relatively lightweight. It supports writing content in Markdown (a simple text formatting shorthand that converts to nicely styled pages) and integrates with Git for version control, meaning you can track the history of every change made to your documents. You would use Wiki.js when your team, company, or community needs a private, searchable, structured place to write and share documentation, but you want to own and host the data yourself rather than pay for a SaaS tool. It's cross-platform and can be deployed via Docker (a container tool) for straightforward installation. The project is licensed under AGPLv3, which means you can use and modify it freely but must share changes if you distribute it. The README primarily contains links to documentation and community channels. The full README is longer than what was provided, so additional setup details and feature specifics are in the official documentation at docs.requarks.io.
