Easy peasy authoring

Create your diagram in minutes. Arrange, select, resize, connect, copy, and export through our simple diagram tool, powered by the most awesome Excalidraw whiteboard.

Dynamic Shapes

Modify shape properties in real-time to create dynamic diagrams. SDShapes can represent domain-specific items (think server diagrams, HVAC systems, sales workflows, whatever you can imagine...)

Live state API

Set current shape values with API calls. The API has fully scoped permissions, validation, quotas, and idempotent requests.

AI Agent-ready design

Let your AI agent inspect diagrams and update current values. MCP access starts at Pro. Agents can read existing diagrams and set enabled shape properties. They cannot create diagrams, draw shapes or change the diagram's layout through MCP.

Controlled sharing

Decide who sees what. Keep diagrams private, organization-visible, specifically shared, or available to all signed-in SimpleDiagrams users.

Organize with libraries

Organize platform and team-owned SDShapes into more than one domain library.
