Write Your Next Microservice with Helidon
Simple and Fast
Helidon is designed to be simple to use, with tooling and examples to get you going quickly. Since Helidon is simply a collection of Java libraries running on a fast Netty core, there is no extra overhead or bloat.
Full MicroProfile Support
Helidon supports MicroProfile and provides familiar APIs like JAX-RS, CDI and JSON-P/B. Our implementation runs on our fast Helidon Reactive WebServer.
Reactive WebServer
Helidon Reactive WebServer provides a modern functional programming model and runs on top of Netty. Lightweight, flexible and reactive, the Helidon WebServer provides a simple-to-use and fast foundation for your microservices.
Observable and Resilient
With support for health checks, metrics, tracing and fault tolerance, Helidon has what you need to write cloud-ready applications that integrate with 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.
Persistence Support
Helidon fully supports DB connectivity. Its non-blocking database client supports existing blocking JDBC drivers as well as relational and non-relational databases.
Features That Make the Difference
All the cloud-native features you need in a declarative programming model based on industry standards.
