What is GoJS?

What Is GoJS?

GoJS is a commercial JavaScript library for building interactive diagrams, charts, and graphs in web applications. It handles the rendering, layout, and user interaction for complex visual structures like flowcharts, org charts, BPMN diagrams, network topologies, and more.

Key Features

GoJS provides automatic layout algorithms (tree, force-directed, layered, circular), data binding to JSON models, undo/redo support, and extensive customization of node and link appearance. It supports drag-and-drop, selection, resizing, linking, grouping, and context menus out of the box.

The library renders to HTML Canvas for performance, handling thousands of nodes smoothly. It includes built-in support for overview panels, palettes, and printing. Comprehensive documentation and over 200 sample diagrams make it relatively quick to get started.

Pricing

GoJS requires a commercial license for production use. Pricing starts at approximately 2,995 dollars for a single developer license. A free evaluation version is available for development and testing.

GoJS vs JointJS

GoJS and JointJS are the two leading JavaScript diagramming libraries. GoJS uses Canvas rendering for better performance with large diagrams, while JointJS uses SVG for easier CSS styling. GoJS has more built-in layout algorithms; JointJS offers more flexibility in custom rendering.
