Liberty: any application anywhere

Liberty is a fast, flexible, and developer-friendly runtime for enterprise Java applications running on bare metal, in VMs, containers, across hybrid and multi-cloud environments.  With extensive support for popular frameworks and standards, its revolutionary architecture frees applications from future code and configuration changes while ensuring technical currency. Liberty is available as an upstream open-source project Open Liberty and the downstream IBM WebSphere Liberty.

Dramatically reduce your runtime compute requirements by up to 80% disk and 50%+ memory savings.4

Every modern runtime in JSphere Suite is built on Liberty.

Modernized Runtime Extension for Java (MoRE) enables Liberty workloads to be managed via WebSphere ND together with traditional WebSphere applications using wsadmin, Admin Console, and scripts. This allows your applications to leverage the features and capabilities of newer Java SE and EE versions while maintaining existing operations with WebSphere ND.
WebSphere Liberty is also an ideal runtime for on-premise workloads but has its own admin strategy.

Library Support for Open-Source
Keep your Java 8, mission-critical apps secure—without a costly rewrite. IBM® Library Support for Spring and Struts adds enterprise-grade security, compliance, and stability to legacy frameworks (e.g., Spring Boot 3.2, Apache Struts 1.3). Maintain uptime, reduce risk, and free your teams to focus on innovation. Use this with WebSphere® Application Server (WAS, WAS ND), WebSphere Liberty, Red Hat® JBoss EAP, and other enterprise Java runtimes.
