1 Overview

GrailsFlow is an open source Workflow and Process Engine, written using Groovy and Grails (Grails Plugin) which can be easily integrated with other Java, Groovy or Grails applications.

GrailsFlow provides:

  • complete out of the box workflow and process management system
  • a very simple structure which is easy to understand
  • Groovy based DSL to define the process, not an XML
  • complete user interface for process definition, worklist management and process monitoring


The application is written in Groovy and Grails. Process Definitions are stored as plain Groovy classes, that fulfill certain coding conventions. The integration of GrailsFlow into Grails is in some respect similar to the integration of Spring Webflow.

The target usage of the system is for midsize applications with 10,000's of processes in the application and hundreds of new processes per day. Currently, it does not aim to be a solution to manage millions of processes per year, however the design would allow that.


GrailsFlow has been developed by jCatalog Software AG.

We would be glad to get any feedback, bug reports, software extensions etc Currently, while the software is open source, we do not have an open repository, so send any comments, extensions and changes via email. Contact information can be found in - www.grailsflow.org.


If you would like to understand GrailsFlow, you first might want to check the demo on www.grailsflow.org.
