Our review
Pros	Embeds Tomcat, Jetty, or Undertow servers Starter dependencies and auto-configuration simplify setup Includes production metrics, health checks, and management endpoints	GORM supports relational and non-relational data access. Web and REST profiles, HTML and JSON views support full-stack work. Gradle tooling, plugins and asynchronous programming extend the framework.
Cons	Focused on Java backend applications built on Spring Production management capabilities are centered on HTTP endpoints or JMX Executable JARs and WARs require different deployment approaches	Requires JVM and Groovy or Java expertise. Deployment is self-hosted rather than managed. Support is through community resources and documentation.
