What it is
Framework or platform
What it does
A Java application framework with dependency injection, AOP, web, RPC and cloud modules, built from scratch as a lighter alternative to Spring and supporting Java 8 through 26 and GraalVM native images.
Adopt it when
You build Java services and want faster startup, smaller packages and lower memory than Spring Boot, and can live outside the Spring ecosystem.
Watch out
Its community and documentation are mainly Chinese, and leaving Spring means losing its large library and hiring ecosystem.
