pyc-wheel
Compile all py files in a wheel to pyc files.
Decision gist · record as of 2026-08-14
Yes, if you need to pre-compile wheels in a build pipeline or distribution workflow. Low friction, no vulnerabilities, actively maintained, and permissive license. Not necessary for typical development; primarily a packaging tool for release or deployment automation.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.11 or higher; operates on wheel files, not source distributions.
- Low install friction; pure Python wheel with minimal dependencies (typing-extensions, setuptools, pkg-about).
- Actively maintained with recent release (73 days ago) and no known vulnerabilities.

What it is and what it does
pyc_wheel is a command-line tool that processes wheel archives to pre-compile their Python source files into bytecode. It reads a .whl file, compiles all .py modules to .pyc, and rewrites the wheel in place or with optional renaming to indicate the Python version used for compilation. The tool supports selective compilation via regex exclusion patterns and can create backups before modification.
Typical use is in build pipelines where you want to distribute pre-compiled wheels for faster installation or to obfuscate source code. It depends on typing-extensions, setuptools, and pkg-about, and runs on Python 3.11 or higher across CPython, PyPy, and GraalPy. The package is actively maintained and carries no known security vulnerabilities.
Use it for
- Pre-compile wheels in CI/CD pipelines to reduce installation time on target systems
- Distribute bytecode-only wheels to obscure source code while preserving functionality
- Rename generic py3 wheels to version-specific cp313 wheels after compilation
- Batch-process multiple wheels with selective file exclusion via regex patterns
