Business Process Server

WSO2 Business Process Server (WSO2 BPS) capabilities are now available within WSO2 Enterprise Integrator (WSO2 EI). WSO2 EI allows you to support business processes by using functionality from WSO2 BPS to model business processes, deploy and manage flows within an SOA, and create long-running business processes across the enterprise. Try it now!

The 100% open source, highly scalable and lean WSO2 Business Process Server helps to increase productivity and enhance competitiveness by enabling developers to easily deploy business processes and models written using Web Services Business Process Execution Language (WS-BPEL) and Business Process Model and Notation (BPMN) standards respectively. It also serves as the business process management and hosting environment for your SOA.

Business Process Server

Version 3.6.0


The web-based graphical console helps to manage, deploy, view and execute business processes and human tasks within a single server instance. The BPEL engine is powered by Apache Orchestration Director Engine (ODE) while the BPMN 2.0 Engine is powered by Activiti allowing you to define and execute BPMN 2.0 business process models. WSO2 BPS provides an interface to assign, allocate, claim and complete tasks with the use of a dashboard.

Third-party applications can be integrated with WSO2 BPS through REST API. WSO2 BPS provides comprehensive management APIs to build external UI’s that interact with processes and tasks deployed in it.
