GraalVM’s polyglot capabilities make it possible to mix programming languages in a single application while eliminating any foreign language call costs. GraalVM offers two ways to run Java applications: on the HotSpot JVM with Graal just-in-time (JIT) compiler or as an ahead-of-time (AOT) compiled native executable. Besides Java, it provides runtimes for JavaScript, Ruby, Python, and a number of other popular languages.
GraalVM contains a compatible JDK and offers distributions based on Java 11, and Java 17. GraalVM comes with multiple compiler optimizations, designed to accelerate Java applications performance while consuming fewer resources.
