What Imixs-Workflow is
Imixs-Workflow is a transactional workflow engine for modeling and running business processes on Jakarta EE. It uses BPMN 2.0 for event-based processes, business rules, automatic actions, and approval workflows. Each process instance can have its own access control list, with task-level owner, read, and write access defined in the BPMN model. Its REST API exposes workflow, model, report, document, administration, event-log, and scheduler resources, with business objects available in JSON and XML.
The engine can run as a Docker-containerized microservice or be embedded in Jakarta EE applications. Java plugins and adapters can extend workflow processing, and adapters can call external microservices. Imixs-Forms provides ready-to-use JavaScript components for building workflow-enabled web applications. The Imixs Security OIDC module supports browser login and bearer-token authentication for REST APIs with providers including Keycloak, Microsoft Entra ID, Auth0, and Okta. The project is free software under the Eclipse Public License 2.0, with a secondary license for GPL-2.0-or-later compatibility. It has no feature limits or license fees, including for production use; the project provides documentation and a community forum, while the maker offers professional services and consulting.
