OpenWMS.org
What it is
OpenWMS.org is open-source software for building warehouse management systems and intralogistics projects. It combines warehouse and transport management with connections to other systems, and organizes business functions as independently deployable microservices. Integrators and customer DevOps teams can adapt and operate it for specific warehouse projects. Deployment options include cloud, fog or private cloud, hybrid, and monolith; services can also run without cloud infrastructure. In monolith deployments, elasticity is available at infrastructure level rather than service level. COP is a web application for operators and superusers to manage inventory and processes, while Roma is a handheld application for warehouse operations on phones and tablets. A workflow engine can change material flow handling while operations continue. The software is not tied to a particular database technology, with services able to use relational or NoSQL datastores. The project describes connections to ERP systems and field controllers, along with OAuth 2.0 and OIDC authentication and authorization. Interfaces include Grafana for monitoring and Kibana for transaction monitoring and log analysis. The project founder has actively developed OpenWMS.org since 2005. The software is free, and the project invites prospective users needing support or an end-customer project to contact the team.
For and against
For
- Combines warehouse and transport management.
- Business functions are independently deployable microservices.
- Supports cloud, fog, hybrid, and monolith deployment.
- COP manages inventory and processes through a web interface.
- Services can use relational or NoSQL datastores.
Against
- Monolith elasticity is at infrastructure rather than service level.
- Public cloud services require valid access tokens.
- Online services require account registration.
- The demo UAA endpoint has no SLA.
The verdict
OpenWMS.org offers a flexible base for warehouse and intralogistics projects, with multiple deployment models and operator interfaces. Teams should account for its monolith elasticity limit and access requirements for online services.
Who it suits
OpenWMS.org is aimed at integrators and customer DevOps teams building and operating warehouse projects. It may suit organizations prepared to extend and customize an open-source system for their intralogistics requirements.
