freeze-core

What it is and what it does

freeze-core is the foundational library that cx_Freeze depends on to convert Python applications into standalone executables. It provides low-level utilities for file handling, archive manipulation, and text processing essential to the freezing process. The package is written partly in C and distributed as precompiled wheels for Python 3.11 through 3.15 across Windows, macOS, and Linux (including ARM and PowerPC variants), reducing installation friction on supported platforms.

As a core dependency rather than a user-facing tool, freeze-core is typically installed automatically when you install cx_Freeze. It requires three runtime dependencies—filelock, cabarchive, and striprtf—all pulled in automatically. The package is actively maintained with no known security vulnerabilities.

Use it for:

• Installed automatically as a dependency when setting up cx_Freeze to package Python applications into standalone executables.
• Provides runtime utilities needed by cx_Freeze to handle file locking during the build process on multi-threaded systems.
• Enables cx_Freeze to process cabinet archives and extract metadata from rich text files during application freezing.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

freeze-core provides core runtime support for cx_Freeze, handling file locking, cabinet archive operations, and rich text format processing needed during application freezing.

Yes, if you are using cx_Freeze to create standalone Python executables. Install it directly only if you have a specific need for its utilities; otherwise, it will be installed automatically as a cx_Freeze dependency. The package is actively maintained, carries no known vulnerabilities, and supports current Python versions with prebuilt wheels that minimize compilation overhead.

Install

freeze-core on PyPI

pip install freeze-core

uv add freeze-core

poetry add freeze-core

Installing freeze-core

Before you install

Medium install friction due to compiled C extensions across multiple platforms. Actively maintained with a release 2 days old; supports Python 3.11–3.15 with prebuilt wheels for common platforms.

License in practice

MIT license permits unrestricted use, modification, and distribution in both open-source and commercial projects with minimal obligations.

Quickstart

pip install freeze-core

import filelock
import cabarchive
import striprtf

Requires Python 3.11 or later; prebuilt wheels available for Windows, macOS, and Linux (x86_64, aarch64, ppc64le, arm64, musllinux).

Verify before relying

• Whether freeze-core can be used standalone or only as a cx_Freeze dependency
• Specific functionality provided by filelock, cabarchive, and striprtf in the freezing workflow
• Performance characteristics or limitations when freezing large applications
