bpmn.io vs PRIME BPM

bpmn.io is a free collection of web tools and embeddable JavaScript components for viewing, annotating, and editing BPMN 2.0, CMMN, DMN, and forms. bpmn-js handles BPMN 2.0 diagrams and can create, embed, or extend them in a browser or application. dmn-js supports DMN 1.3 decision tables, literal expressions, and decision requirement diagrams. cmmn-js works with CMMN 1.1 diagrams in modern browsers. form-js provides visual construction of JSON-based forms and a viewer for embedding forms in webpages; its editor and viewer do not perform remote interaction. Toolkits are available as pre-built packages or source code, and bpmn-js can be installed through NPM. The license permits use, copying, modification, distribution, and sale, but rendered diagrams must retain the bpmn.io watermark. The separate demo is free but has no availability guarantee, stores submitted models unencrypted, and may delete them.
