Micronaut vs Spring Boot
No clear leader: Spring Boot (63.3) and Micronaut (62.2) are within the 5-point margin; treat as a tie. The attribute-by-attribute breakdown below, with a source and date on every value, is the honest way to compare them.
Capabilities
Feature-by-feature on the axes that matter for web frameworks. “-” means undocumented, not absent.
What each one is
The product in its own terms, so the numbers below have context.
Micronaut
A modern Java framework designed to reduce startup time and memory overhead through compile-time optimization rather than runtime reflection, providing built-in support for dependency injection, aspect-oriented programming, cloud-native patterns, and microservice infrastructure.
Spring Boot
A framework for creating stand-alone, production-grade Spring applications with minimal configuration. Features embedded web servers (Tomcat, Jetty, Undertow), opinionated starter dependencies, automatic configuration, and production-ready features such as metrics and health checks.
