Description
Micronaut is a modern, JVM-based, full stack Java framework designed for building modular, easily testable JVM applications with support for Java, Kotlin and the Groovy language.
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 aims to provide all the tools necessary to build JVM applications including:
Dependency Injection and Inversion of Control (IoC)
Aspect Oriented Programming (AOP)
Sensible Defaults and Auto-Configuration

Micronaut Framework
Micronaut Framework is a modern, JVM-based, full stack Java framework designed for building modular, easily testable JVM applications with support for Java, Kotlin and the Groovy language.
Micronaut Framework 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 Framework aims to provide all the tools necessary to build JVM applications including:
- Dependency Injection and Inversion of Control (IoC)
- Aspect Oriented Programming (AOP)
- Sensible Defaults and Auto-Configuration
With Micronaut Framework you can build Message-Driven Applications, Command Line Applications, HTTP Servers and more whilst for Microservices in particular Micronaut Framework also provides:
- Distributed Configuration
- Service Discovery
- HTTP Routing
- Client-Side Load Balancing
At the same time Micronaut Framework aims to avoid the downsides of frameworks like Spring, Spring Boot and Grails by providing:
- Fast startup time
- Reduced memory footprint
- Minimal use of reflection
- Minimal use of proxies
- No runtime bytecode generation
- Easy Unit Testing
This is achieved by pre-computing the framework infrastructure at compilation time which reduces the logic required at runtime for the application to work.
For more information on using Micronaut Framework see the documentation at micronaut.io
Example Applications
Example Micronaut Framework applications can be found in the Examples repository
