Micronaut - A modern, JVM-based, full-stack framework for building modular, easily testable microservice and serverless applications

Micronaut is a modern, JVM-based, full stack microservices framework designed for building modular, easily testable microservice applications. Micronaut is developed by the creators of the Grails framework and takes inspiration from lessons learnt over the years building real-world applications from monoliths to microservices using Spring, Spring Boot and Grails.

Micronaut apps startup in tens of milliseconds with GraalVM. It features a Dependency Injection and Aspect-Oriented Programming runtime that uses no reflection. Micronaut's Cloud support is built right in, including support for common discovery services, distributed tracing tools, and cloud runtimes.
