Grumpy is a Python-to-Go source code transcompiler and runtime from Google, intended as a near drop-in replacement for CPython 2.7. It compiles Python source into statically-compiled Go code with no VM, though it lacks support for dynamic execution, C extensions, and much of the standard library.

Use cases

• compile python code to native binaries
• run python 2.7 programs without a vm
• transpile python to go source code
• integrate python logic into go applications
• speed up python by compiling to native code

When to choose

• you have legacy Python 2.7 code you want to compile to native Go binaries
• you want to embed Python logic inside a Go program without a CPython runtime
• your code avoids exec/eval, C extensions, and heavy standard library use

When to avoid

• you need Python 3 support
• you rely on C extension modules or dynamic features like exec and eval
• you need a complete Python standard library
• you want an actively maintained tool - the project is effectively abandoned
