Central draw.io diagram management for your organization

diagramHub centralizes, secures, and standardizes your draw.io diagrams across your organization — with Entra ID SSO and optional self-hosting.

Entra ID SSO • AI assistants via MCP • Self-hosted option available

Your diagrams are scattered. Your knowledge is leaking.

In most companies, diagrams live everywhere:
Where diagrams end up today
  • SharePoint folders
  • Confluence pages
  • Git repositories
  • Local files

No ownership, no structure, no visibility.

That leads to
  • Lost architecture knowledge
  • Duplicate or outdated diagrams
  • Painful onboarding for new engineers
  • Risk during audits and compliance reviews

Let your AI assistant draw and update your diagrams

diagramHub includes a built-in MCP server. Connect Claude, GitHub Copilot or your local AI and work on your draw.io diagrams in plain language, with the same permissions you have in diagramHub.
Ask about your architecture

Find diagrams across all collections and let the AI explain systems, flows and their documentation.

Create diagrams from a prompt

Describe a system, paste code or a spec, and get a clean, editable draw.io diagram in your collection.

Update existing diagrams

Add services, rename components or restructure pages. Everyone with the diagram open sees the change live.

You

Open the "Payment Platform" diagram and add a fraud check service between the API gateway and the payment service.

AI assistant

✓ search_diagrams "Payment Platform"
✓ get_diagram
✓ update_diagram (version saved before the change)

Done. I added "Fraud Check" and connected it between the API Gateway and the Payment Service. You can restore the previous state from the version history at any time.

Your permissions, nothing more

The AI only sees and changes what you can. Personal access tokens can be read-only, expire and be revoked any time.

Every AI edit is reversible

A version is saved before the AI changes a diagram, and every change is recorded in the audit log.

Works with the AI you already use

Claude, GitHub Copilot in VS Code, Claude Code and any other MCP compatible client, including local models.
