Simple and Fast
Helidon is designed to be simple to use, with tooling and examples to get you going quickly. Helidon WebServer is the world's first web server written from scratch that is fully based on virtual threads.
Full MicroProfile Support
Helidon supports MicroProfile and provides familiar APIs like JAX-RS, CDI and JSON-P/B. Our implementation runs on our Helidon WebServer.
Helidon WebServer
Helidon WebServer provides a modern functional programming model and runs on virtual threads. Lightweight and flexible, the Helidon WebServer provides a simple-to-use and fast foundation for your microservices.
Observable and Resilient
With support for health checks, metrics, telemetry and fault tolerance, Helidon has what you need to write cloud-ready applications that integrate with Opentelemetry, Prometheus, Jaeger/Zipkin and Kubernetes.
GraalVM Native Image Support
Helidon supports GraalVM Native Image so you can compile your Helidon application into a small-footprint native executable. Or you can package your application as a jlink image or a traditional application JAR.
