Complete diagramming toolkit

Don't reinvent the wheel. Let us take care of all the math, interactivity and graphics for you. Use a set of pre-built diagramming tools to build an outstanding app while saving months of complex development and avoiding headaches from never-ending code maintenance.

Automatic layouts and link routing

Lay out nodes as an orgchart, flowchart or force-directed graph, and determine link behavior with built-in or custom routers.

Custom SVG or HTML shapes with ports

Provide your own custom shape definitions (including ports) for your diagram nodes using SVG or HTML.

Export/Import, Serialisation

Export your diagrams to various formats (PNG, JPEG, SVG, PDF), or use JSON for an easy integration with your database.


Enable user interaction by triggering events on the JointJS paper, or individual elements and links.

Snaplines, element & link tools

Define custom UI to manipulate elements and links via built-in and custom tools, including snaplines, buttons and connect tools.

Property editor & viewer

Keep all your diagram data in one place using the model-view architecture, and edit it via the property editor & viewer component.

Zoom and pan, copy and paste & undo and redo

Enhance your application with core diagram controls without having to create them from scratch.

Element palette

Organize your shapes in the element palette, then drag & drop to the diagram.
