GraalVM is a high-performance JDK designed to accelerate Java application performance while consuming fewer resources. It provides the Graal compiler, which can be used as a just-in-time compiler to run Java applications on the HotSpot JVM or to ahead-of-time compile them into native executables. Besides Java, it also provides runtimes for JavaScript, Ruby, Python, and a several other popular languages with polyglot capabilities.
