Questions tagged [flowable]

Flowable is a light-weight business process engine written in Java. Use this tag for questions related to Flowable usage and workflows.

The Flowable process engine allows you to deploy BPMN 2.0 process definitions (an industry XML standard for defining processes), creating process instances of those process definitions, running queries, accessing active or historical process instances and related data. It can run as independent engine or as a service and can be integrated with Spring and Spring boot. It even supports DMN decision tables and CMMN case management engines.

Flowable is a fork of Activiti (registered trademark of Alfresco).
