GraalPy is a high-performance Python 3.12 implementation for the JVM built on GraalVM. It supports embedding Python in Java applications and compiling Python programs into fast standalone native binaries.

Use cases

• embed a Python interpreter inside a Java application
• run Python code on the JVM alongside Java libraries
• compile a Python app into a standalone native binary
• replace CPython with a faster Python runtime
• sandbox Python library system access with Java-based permissions
• run pure Python packages like NumPy or PyTorch on GraalVM

When to choose

• you need first-class Python-Java interoperability on the JVM
• you want to ship Python applications as standalone native executables
• your workload is pure Python and you want GraalVM performance benefits
• you need fine-grained control over Python code's system access from Java

When to avoid

• you depend heavily on CPython-specific native extensions, which are only experimentally supported
• you need 100% CPython compatibility for your test suite
• you are not on the JVM ecosystem and have no need for GraalVM
