Maintaining a centralized knowledge base is critical for any small team striving to stay organized, efficient, and agile. However, relying on third-party SaaS platforms for documentation can lead to ongoing monthly fees, lack of data ownership, and potential privacy concerns. That’s where self-hosted wiki and documentation tools step in — giving teams full control without recurring subscription costs.
TL;DR
If you’re part of a small team looking for a cost-effective, self-hosted solution to manage internal documentation, there are several great opensource options to choose from. This article highlights the top 5 tools — Docmost, Wiki.js, Affine, Docs, and BookStack — that are widely used by teams for maintaining wikis and internal knowledge bases. Each tool brings its own unique set of features tailored to various workflow styles. Skip the SaaS fees and gain full control over your data with these reliable platforms.
1. Docmost – Markdown-First Simplicity
Docmost shines as a simple, markdown-centric documentation system perfect for small developer teams or content writers who prefer working in plain text. It’s designed to be lightweight and easy to set up, with a focus on keeping your writing and version control in sync.
- Tech Stack: Node.js, Markdown-based content structure
- Key Features: Git support, static Markdown rendering, folder-based structure
- Ideal For: Teams that are already using Git workflows
Once deployed, Docmost reads your markdown files directly from your Git repository, making it a powerful option if you want a single source of truth for your docs — tightly integrated with your codebase.
2. Wiki.js – Feature-Rich and Flexible
Wiki.js is one of the most popular open-source wiki platforms available today. Built on Node.js and designed with flexibility in mind, Wiki.js supports multiple editors (Markdown, WYSIWYG, and even raw HTML), integrates with tons of authentication providers, and can be customized to your team’s needs.
- Tech Stack: Node.js with PostgreSQL or other backend DBs
- Key Features: Access control, versioning, visual editor, multiple themes, backups
- Ideal For: Technical and non-technical teams needing visual editing features
You can configure Wiki.js to host your documentation site publicly or privately, making it versatile for both internal and external docs. The built-in permission system is highly granular, so you can manage who sees and edits what with precision.
3. Affine (Self-Hosted) – A Notion-Like Power Tool
Affine is a relatively new entrant that feels like a fusion between Notion and Obsidian. It focuses on modularity and visual design, offering robust block-style content editing in a modern UI. The self-hosted version gives your team access to all of its powerful features, minus any cloud dependency.
- Tech Stack: Electron, Rust, and web technologies
- Key Features: Docs, whiteboarding, kanban boards, visual blocks
- Ideal For: Remote or hybrid teams desiring visual documentation and project tracking
Affine also blurs the line between note-taking and project management. If your team prefers a more graphical interface for organizing thoughts, linking ideas, and planning work, Affine’s block-based canvas is worth exploring.
4. Docs by Docusaurus – Dev-Friendly Docs Engine
Docusaurus, created by Facebook, is a static site generator optimized for documentation websites. While it’s widely known as a platform for website-based docs, its internal modular system (“Docs”) enables an excellent self-hosted knowledge base experience for developer-focused teams.
- Tech Stack: React, Markdown, Static Site Generation
- Key Features: Fast performance, versioning support, fully customizable theme
- Ideal For: API documentation, developer guides, open source project manuals
Configure it with GitHub Pages or host it yourself, and you instantly get a modern, high-speed documentation site. The built-in search (powered by Algolia DocSearch or others) enhances accessibility and navigation.
Keep in mind that Docusaurus is ideal if at least one person on your team is comfortable with React or front-end tooling, as it may require some customization.
5. BookStack – User-Friendly and Structured
Last but not least, BookStack is tailor-made for teams that want a simplified structure for their documentation without sacrificing usability. Inspired by the metaphor of physical books, each “book” contains “chapters” and “pages” – providing a naturally organized way to document workflows, SOPs, or internal wikis.
- Tech Stack: PHP (Laravel), MySQL or MariaDB
- Key Features: WYSIWYG editor, permissions, themes, roles, easy self-hosting
- Ideal For: Non-technical teams, customer support, content editors
BookStack offers an elegant UI that won’t intimidate users unfamiliar with Markdown or code. Its visual hierarchy and simple navigation make it a favorite for HR teams, internal training docs, and customer support resources.
Whether you’re hosting on a VPS or a home server, BookStack is light on resources and well-documented for installations.
Choosing the Right Tool for Your Team
Selecting the perfect self-hosted wiki tool depends on your team’s size, tech comfort level, and how structured your documentation needs to be. Here’s a quick breakdown to guide your choice:
| Tool | Best For | Requires Coding Knowledge? |
|---|---|---|
| Docmost | Markdown authors and developers | Yes, minimal setup via Git |
| Wiki.js | Mixed technical/non-technical teams | No, but optional customization available |
| Affine | Visual thinkers and hybrid teams | No, modern interface with minimal setup |
| Docusaurus Docs | Frontend developers and API writers | Yes, React or web familiarity helps |
| BookStack | Non-technical teams and general workflows | No, simple and accessible |
Final Thoughts
If your team is fed up with monthly SaaS charges, embracing a self-hosted knowledge base tool is a financially smart and scalable move. Whether you want something highly customizable like Wiki.js, visually engaging like Affine, or dead-simple like BookStack, there is a tool out there that fits the way your team works.
All of these platforms are open-source and benefit from active communities, so you can adapt and grow your documentation system over time. And perhaps best of all, you stay fully in control of your team’s most important knowledge — no subscriptions, no lock-ins, just empowered collaboration.
