Unleash the power of your applications with Micronaut and GraalVM
summary
Micronaut builds framework wiring at compile time using AOT annotation processing, eliminating runtime reflection and proxies so apps start ~3–4× faster and use ~10× less memory. Micronaut Data produces compile-time checked queries (typos fail the build), and test resources spin up Testcontainers automatically for development. GraalVM’s native-image produces OS-specific binaries (demo 37 ms cold start, minimal images ~1.5 MB, typical apps ~40–50 MB) with longer compile times and Maven or Docker build options.
