ArchitectureDiagram.ai vs Gliffy
Gliffy is a diagramming tool that has been embedded in Atlassian Confluence since 2005, offering a traditional drag-and-drop interface with shape libraries for flowcharts, UML diagrams, network diagrams, and AWS architecture. It remains a common choice for teams already in the Atlassian ecosystem. ArchitectureDiagram.ai takes a fundamentally different approach: instead of dragging shapes onto a canvas, you describe your architecture in plain English and get a complete, editable diagram in seconds — with multiple export formats including draw.io XML that integrates with Confluence.
Feature comparison
| Feature | Gliffy | ArchitectureDiagram.ai |
|---|---|---|
| Diagram Creation | Drag-and-drop canvas with shape libraries | Natural language description → instant diagram |
| Time to First Diagram | 15–30 minutes (manual placement and routing) | Under 30 seconds |
| AI Capabilities | Limited AI features; primarily manual | AI generation + Expert Chat for architecture review |
| Confluence Integration | Native embed via Gliffy Confluence plugin | Export to draw.io XML, embed in Confluence via draw.io plugin |
| Output Formats | Gliffy native, PNG, SVG, PDF export | Mermaid, draw.io XML, Excalidraw, AI-generated images |
| AWS/Cloud Icons | AWS, Azure, and GCP shape libraries included | AI-accurate cloud diagrams; draw.io export for official cloud icons |
| Iterating on a Diagram | Manual edits via canvas | Describe the change in plain English to regenerate |
| Pricing | From $7.99/user/month (Confluence Cloud) or per-user Jira pricing | Free tier + paid plans from $4.99/mo |
When to choose Gliffy
Gliffy makes sense in these situations:
- Your team is deeply embedded in the Atlassian ecosystem and wants diagrams natively embedded inside Confluence pages without any additional tooling
- You need fine-grained control over the exact position of every shape and connector — for highly polished, pixel-perfect diagram layouts
- You prefer a traditional drag-and-drop workflow and have established templates and shape libraries your team already uses
- Your Confluence workspace already has Gliffy licensed and re-evaluating tools isn't a priority
When to choose ArchitectureDiagram.ai
ArchitectureDiagram.ai is the stronger choice when:
- Speed is the priority — you need an architecture diagram in seconds for a design review, standup, or RFC, not 20 minutes of drag-and-drop work
- You want to iterate on diagrams conversationally — describe a change and get an updated diagram, rather than manually moving shapes around
- You need multiple output formats: Mermaid for GitHub wikis and Notion, draw.io XML (which also embeds in Confluence via the draw.io plugin), or Excalidraw for collaborative whiteboard sessions
- You want AI to review your architecture — Expert Chat can identify scalability issues, single points of failure, security gaps, and missing components
- Your team includes individual contributors who don't want to pay $7.99+/user/month just to create occasional diagrams
