Our review
Pros	Build for the JVM or as a native executable Live reload and continuous testing in development mode Generate Kubernetes resources and container images	Supports HTTP, timer, queue, and Kubernetes event triggers. Automatically provisions and scales function pods. Offers streaming responses and Prometheus and Fluentd integration.
Cons	No serverless-specific deployment workflow Deployment is self-hosted on infrastructure you select Support channels are community and documentation	Requires teams to operate the Kubernetes infrastructure themselves. Deployment is CLI-based rather than through a hosted service. Functions use a request-based execution model.
