BookStack
BookStack organizes content into a simple books, chapters, and pages structure that non-technical people grasp immediately. It is easy to host, easy to use, and good-looking out of the box, which makes it the safe default for a team wiki.

How to choose
Match the tool to who edits it. BookStack wins when non-technical teammates need to contribute, because its books-and-chapters model is obvious. Wiki.js wins when you want power: multiple editors, git sync, and granular permissions. Outline and Docmost are better if you want a modern, app-like feel closer to Notion, with Outline leaning toward a knowledge base and Docmost toward nested documentation.
Hosting effort differs too. BookStack is the lightest to stand up. Outline and Docmost need Postgres and Redis, so they are a little more to run. If you already use Nextcloud, its built-in collaborative docs may cover light wiki needs without a separate tool.
The verdict
For a team wiki, most people should run BookStack: easy to host, easy to use, and structured so anyone can contribute. Choose Wiki.js for more power and git-backed storage, or Docmost and Outline for a modern, Notion-like experience. If you want a personal Notion replacement instead of a wiki, see our self-hosted alternative to Notion.
FAQ
What is the best self-hosted wiki?
For most teams, BookStack, because it is easy to host, easy to use, and structured so non-technical people can contribute. Wiki.js is better if you need more power and git-backed storage, and Docmost or Outline if you want a modern, Notion-like feel.
Is there a self-hosted Notion alternative?
Yes. Docmost is the closest wiki-style match, with nested pages and real-time editing. For personal Notion-style databases, AppFlowy and AFFiNE are closer; see our Notion alternatives page.
Can a self-hosted wiki sync with git?
Wiki.js can store and sync its content with a git repository, which keeps your docs version-controlled and portable. BookStack keeps content in its database with export options instead.
