JointJS is an open-source JavaScript/TypeScript diagramming library that enables developers to build rich, interactive diagramming tools for modern browsers—using SVG and framework-agnostic APIs. It provides core features like nodes, edges, SVG transformations, drag-and-drop, snaplines, and inline editing. The commercial JointJS+ adds advanced plugins—such as automatic layouts (grid, force-directed), BPMN/UML support, export/import options, presentation features, and white-label components—helping teams prototype and deploy visual tools rapidly. JointJS is SOC 2 Type II compliant, well-documented, and supported by a strong developer community and enterprise-grade support .
JointJS was initially released as an open-source JavaScript library in 2011 by client IO, a software company based in the Czech Republic. It began as a lightweight diagramming library and has grown into a comprehensive toolkit for building advanced visual applications. Over time, JointJS has expanded with commercial extensions and matured into an enterprise-grade framework used globally.
JointJS has been developed and maintained without known external venture funding. It has grown sustainably through a freemium model, offering both a free open-source core and a suite of paid extensions under the JointJS+ commercial license.
JointJS provides a JavaScript library for creating interactive diagrams such as flowcharts, UML diagrams, org charts, BPMN, and custom visualizations. JointJS+ extends the core with features like UI widgets, stencil support, undo/redo, hierarchical layout, and advanced element customization. It is framework-agnostic and integrates with modern frontend tools.
