Quarkus and Spring Native are two frameworks that use GraalVM's Ahead-of-Time (AOT) compilation to achieve sub-10ms startup in Java applications.
Quarkus is designed with GraalVM in mind and provides near-instant startup, reduced memory footprint, and first-class Kubernetes and serverless support.
Spring Native is an extension of Spring Boot that brings native compilation to the Spring ecosystem, but it has reflection-heavy defaults and slower build times compared to Quarkus.
Quarkus is recommended for cloud-native applications with its best-in-class startup time and low memory footprint, while Spring Native is suitable for leveraging existing Spring knowledge and enterprise integrations.
