Draw.io Architecture Libraries

Reusable draw.io / diagrams.net libraries for creating clean, consistent, and professional architecture diagrams.

This repository provides curated symbol libraries for system design, cloud architecture, DevOps, and security diagrams, optimized for clarity, reuse, and documentation quality.

---

🎯 Purpose

Architectural diagrams often fail due to:

• inconsistent symbols
• visual clutter
• lack of shared semantics

This project solves that by offering standardized, reusable libraries that help teams produce diagrams that are:

• easier to read
• easier to maintain
• easier to review

📚 Library Catalog

A visual catalog with descriptions and previews is available here:

👉 CATALOG.md

Each library is independently usable and versioned.

🚀 How to Use

Option 1: Load a single library

1. Open draw.io / diagrams.net
2. Go to File → Open Library from → Device
3. Select the .xml library file
4. Drag symbols into your diagram

Option 2: Use a release pack (recommended)

1. Download a release ZIP from GitHub Releases
2. Extract the libraries
3. Import one or more .xml files into draw.io

🧭 Design Principles

These libraries follow a few strict rules:

• Architecture first — symbols represent concepts, not vendors
• Consistent sizing — predictable alignment and spacing
• Low visual noise — diagrams stay readable at scale
• Print & dark-mode friendly
• Tool-agnostic semantics (works beyond draw.io)

---

🧩 Typical Use Cases

• System architecture diagrams
• C4 (Context / Container / Component) diagrams
• Cloud and infrastructure design reviews
• DevOps and CI/CD flows
• Technical documentation and RFCs
• Architecture review boards (ARB) material

---

📦 Releases & Versioning

This repository publishes versioned release packs.

Each release:

• is tagged (e.g. v1.0.0)
• includes a downloadable ZIP
• contains stable library definitions

👉 See GitHub Releases for downloadable packs.

🤝 Contributing

Contributions are welcome, especially:

• new libraries with clear scope
• refinements to existing symbols
• visual consistency improvements
• documentation and examples

Contribution guidelines:

1. Keep symbols semantic, not vendor-marketing heavy
2. Avoid duplicating icons with different names
3. Prefer fewer, clearer symbols over large icon sets
4. Include a short description for catalog inclusion

---

🛣 Roadmap

• Expand catalog previews
• Add more C4-aligned symbols
• Add example diagrams per library
• Provide light/dark theme variants
• Improve cross-library consistency

⭐ Why This Repo Exists

Good diagrams are a force multiplier for engineering teams.

This repository exists to make clear architecture diagrams the default, not the exception.
