Open Liberty is a lightweight, composable Java application server runtime for building cloud-native microservices with MicroProfile and Jakarta EE features. It offers fast startup, low memory footprint, live reload dev mode, and zero-migration upgrades across runtime versions.

Use cases

  • run jakarta ee applications on a lightweight server
  • build cloud-native java microservices
  • develop rest apis with microprofile
  • deploy java apps to kubernetes containers
  • hot reload java code during development
  • expose business logic as mcp tools for ai agents
  • monitor microservices with prometheus metrics and opentelemetry

When to choose

  • you want a fast-starting, low-memory Java runtime with only the features you need
  • you build MicroProfile or Jakarta EE microservices and want zero-migration upgrades
  • you want integrated dev mode with live reload, testing, and debugging
  • you deploy containerized Java apps on Kubernetes

When to avoid

  • you need a non-JVM stack
  • you want a minimal embedded HTTP server without an application server model
  • you prefer Spring Boot's ecosystem and programming model
