description Micronaut Overview

Micronaut is an open-source application framework for the Java Virtual Machine (JVM) created by Object Computing. It utilizes compile-time dependency injection instead of reflection to achieve fast startup times and a low memory footprint. The framework is designed primarily for building microservices and serverless applications, supporting programming languages such as Java, Kotlin, and Groovy. By eliminating runtime reflection, it is well-suited for environments where resource efficiency is critical, including GraalVM native images.

help Micronaut FAQ

What is Micronaut used for?

Micronaut is a JVM framework for building microservices, HTTP APIs, and cloud-native applications. Object Computing created it with a focus on fast startup and low memory use.

Why does Micronaut use compile-time dependency injection?

Micronaut generates much of its dependency-injection information during compilation instead of relying heavily on runtime reflection. This can reduce startup work and make the framework suitable for serverless and small-container deployments.

Which languages can be used with Micronaut?

Micronaut supports Java, Kotlin, and Groovy applications. It also provides integrations for HTTP servers, configuration, security, messaging, and common cloud services.

How is Micronaut different from Spring Boot?

Both frameworks target JVM services and support dependency injection, HTTP, configuration, and cloud applications. Micronaut emphasises compile-time processing and low runtime overhead, while Spring Boot has the larger and older ecosystem.
