PyLingual is a CPython bytecode decompiler that recovers Python source code from .pyc files for all Python versions since 3.6. It can be run as a local CLI tool or through a hosted web service, and uses machine-learning-based segmentation for control flow reconstruction.

Use cases

• decompile pyc files back to python source
• recover lost python source code from bytecode
• analyze python malware without source
• decompile python 3.12 bytecode
• reverse engineer compiled python packages
• convert pyc to py

When to choose

• you need to decompile bytecode from modern Python versions 3.6-3.14
• other decompilers like uncompyle6 fail on recent Python versions
• you want a research-grade decompiler with ML-based control flow recovery

When to avoid

• you only need to inspect bytecode disassembly rather than recover source
• you need guaranteed perfect source recovery - decompilation can be imperfect
• you need a decompiler for Python versions older than 3.6
