Alexandrie Hub: A Gorgeous Self-Hosted Note-Taking Knowledge Base Alternative

If you are active in the self-hosting or personal knowledge management (PKM) communities, you already know the never-ending struggle of finding the perfect note-taking system.

On one side, you have cloud-based proprietary tools like Notion or Evernote. While they look gorgeous and work across every web browser out of the box, you are trusting a third-party company with your personal notes, ideas, and data. On the other side, local-first powerhouses like Obsidian and Logseq give you 100% data ownership in raw Markdown files—but accessing your notes seamlessly across locked-down work laptops, tablets, and web browsers requires custom sync setups or extra container configurations.

That is where Alexandrie Hub enters the scene. Developed as an open-source, web-first self-hosted knowledge base, Alexandrie Hub combines the visual elegance of a modern web app with the privacy and control of self-hosting your own Markdown engine.

In this guide, we'll dive into what makes Alexandrie Hub special, review its best built-in features, compare it directly to tools like Obsidian and BookStack, and show you how easy it is to spin up inside your home lab.

What is Alexandrie Hub?

Alexandrie Hub is an open-source web application crafted specifically for building personal knowledge bases, team documentation, and daily technical notes. Created by developer Smaug6739, the project was inspired by the legendary Library of Alexandria—aiming to create a central, resilient sanctuary for all your accumulated knowledge.

Unlike heavy enterprise wiki platforms that require complex relational databases and slow PHP runtimes, Alexandrie Hub is built on modern web technologies. It is lightweight, blazingly fast, and designed from day one to live happily inside a standard Docker container on your home server, Proxmox cluster, or Raspberry Pi.

5 Standout Features That Make Alexandrie Hub Shine

Testing out Alexandrie Hub in a rookie home lab reveals several killer features that immediately stand out compared to traditional wiki alternatives:

1. Clean, Distraction-Free Live Markdown Editing

If you enjoy writing in pure Markdown syntax—headers with #, lists with -, and code fences with triple backticks—Alexandrie provides a smooth real-time editor that renders your formatting without clunky page refreshes. You get the speed of plain text combined with rich visual formatting.

2. Interactive Knowledge Graph Visualization

One of the biggest reasons people love tools like Obsidian is the visual Graph View—seeing how your ideas, technical tutorials, and project notes connect in an interactive node web. Alexandrie Hub brings this interactive graph view directly into your web browser, letting you explore interconnected notebooks effortlessly.

3. Built-In Diagramming (Mermaid & Visual Charts)

Home lab builders and software developers frequently create network diagrams, workflow flowcharts, and system architecture sketches. Alexandrie Hub has native support for Mermaid diagrams, allowing you to turn simple text blocks into beautiful, glowing flowcharts without needing third-party drawing plugins.

4. Native Web-First Architecture

Because Alexandrie Hub is a web service running on your server, you don't have to install desktop client software on every machine you touch. Open Google Chrome, Firefox, or Safari on your desktop, laptop, iPad, or phone, log into your instance, and your entire knowledge base is immediately ready.

5. Simple Notebook & Tag Organization

Rather than forcing you into rigid folder trees, Alexandrie balances intuitive notebook groupings with flexible tagging. Whether you are cataloging home server IP addresses, documenting Docker Compose snippets, or drafting personal journal entries, your content stays organized and instantly searchable.

How to Deploy Alexandrie Hub with Docker Compose

Deploying Alexandrie Hub on your home server takes less than five minutes using Docker Compose. Here is a starter configuration you can use to launch your instance:

services:
  alexandrie:
    image: ghcr.io/smaug6739/alexandrie:latest
    container_name: alexandrie_hub
    restart: unless-stopped
    ports:
      - "3000:3000"
    environment:
      - NODE_ENV=production
      - PORT=3000
    volumes:
      - ./alexandrie-data:/app/data

Save this file as docker-compose.yml in a dedicated folder on your server (for example, ~/docker/alexandrie), then launch it in the background:

docker compose up -d

Once the container finishes starting up, open your favorite browser and navigate to http://YOUR-SERVER-IP:3000 to complete your initial account registration.

Who is Alexandrie Hub Best For?

Alexandrie Hub is the ideal choice if:

You want a clean, zero-configuration web interface that you can access from any work machine or Chromebook without installing software.
You love the visual aesthetic of modern SaaS platforms but demand 100% self-hosted data ownership.
You want visual graph views and Mermaid diagramming out of the box without tweaking dozens of community plugins.

Stick with Obsidian if:

You want raw .md text files stored on your local hard drive that you can edit even when completely offline without an internet or server connection.
You rely heavily on complex community plugins like Dataview, Templater, or Kanban boards. (Check out our Obsidian Plugins Guide and Part 2 Plugins Tutorial).
