What bpmn.io is

bpmn.io provides free web tools and JavaScript toolkits for BPMN 2.0, CMMN, DMN, and forms. The bpmn-js toolkit views and edits BPMN 2.0 diagrams and can be embedded or extended in a browser or application. dmn-js handles DMN 1.3 decision tables, literal expressions, and decision requirement diagrams; cmmn-js supports CMMN 1.1 diagrams in modern browsers. form-js visually builds JSON-based forms and provides a viewer for embedding them in webpages. These toolkits are embeddable building blocks, and the form-js editor and viewer do not make remote connections. They are available as pre-built packages or source code, and bpmn-js can also be installed through NPM. The license permits free use, copying, modification, distribution, and sale, but rendered diagrams must retain the bpmn.io watermark. The separate demo service has no availability guarantee and is offered without warranty. Models submitted through its JavaScript embedding feature are stored unencrypted and may be deleted at any time. The project points users to a forum for toolkit questions and reports.
