Lagom

Lagom is an open source framework for building systems of Reactive microservices in Java or Scala. Lagom builds on Akka and Play, proven technologies that are in production in some of the most demanding applications today.

Lagom's integrated development environment allows you to focus on solving business problems instead of wiring services together. A single command builds the project, starts supporting components and your microservices, as well as the Lagom infrastructure. The build hot-reloads when it detects changes to source code.

Right-sized services created with Lagom enable:

  • better defined development responsibilities—to increase agility
  • more frequent releases with less risk—to improve time to market
  • systems with reactive qualities: responsiveness, resilience, scalability, and elasticticity—to make best use of modern computing environments and meet demanding user expectations
