What bpmn.io is

bpmn.io provides free web tools and JavaScript toolkits for working with 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 supports DMN 1.3 decision tables, literal expressions, and decision requirement diagrams, while cmmn-js supports creating and extending CMMN 1.1 diagrams in modern browsers. form-js lets users visually build JSON-based forms and embed a form viewer in webpages. The toolkits are JavaScript building blocks available as pre-built packages or source code; bpmn-js can also be installed through NPM. The form-js editor and viewer do not make remote connections. The license permits free use, copying, modification, distribution, and sale, but the bpmn.io watermark must remain visible in rendered diagrams. The separate demo service has no availability guarantee and is offered without warranty. Models submitted through its JavaScript embedding functionality are stored unencrypted and may be deleted at any time. The project points users to its forum for toolkit questions and problems. Previously limited touch interaction support was removed in 2024 without an immediate replacement.
