getpybs

Fetch python-build-standalone binaries easily.

getpybs is a command-line tool that simplifies downloading pre-built Python binaries from the python-build-standalone project. These are self-contained, portable Python distributions that work across different platforms without system dependencies.

Installation

Use directly with uvx

Downloads latest build and python version for your OS

uvx getpybs

Install from PyPI

pip install getpybs

Usage

Download the latest Python build for your current platform:

getpybs

Download a specific Python version:

getpybs --python-version 3.12

Download for a specific architecture:

getpybs --architecture x86_64-apple-darwin

Download a specific release version:

getpybs --build-version 20250920

Options

getpybs [options]

• --build-version VERSION: Release version - either latest or a specific release tag like 20250920 (default: latest)
• --python-version VERSION: Python version to download (default: latest stable)
• --architecture ARCH: Target architecture (default: auto-detected)
• --build-config CONFIG: Build configuration (default: pgo+lto)
• --content-type TYPE: Content type (default: install_only_stripped)
• --windows-variant VARIANT: Windows variant (shared or static)
• --dest PATH: Download destination directory (default: current directory)
• --list-options: Show all available options

Examples

Download the fastest Python build (PGO+LTO optimized):

getpybs --build-config pgo+lto

Download a specific release for Linux ARM64:

getpybs --build-version 20250920 --architecture aarch64-unknown-linux-gnu

Download with full build artifacts:

getpybs --content-type full

Architectures

• aarch64-apple-darwin - macOS ARM CPU (M1, M2, M3, etc.)
• x86_64-apple-darwin - macOS Intel CPU
• x86_64-pc-windows-msvc - Windows 64-bit Intel/AMD CPU
• i686-pc-windows-msvc - Windows 32-bit Intel/AMD CPU
• x86_64-unknown-linux-gnu - Linux 64-bit Intel/AMD CPU (baseline), linked with GNU libc
• x86_64_v2-unknown-linux-gnu - Linux 64-bit with SSE4.2/SSSE3 (recommended, widely compatible, ~2011+ CPUs)
• x86_64_v3-unknown-linux-gnu - Linux 64-bit with AVX2/FMA3 (faster, ~2013+ CPUs like Haswell)
• x86_64_v4-unknown-linux-gnu - Linux 64-bit with AVX-512 (fastest, high-end CPUs only)
• x86_64-unknown-linux-musl - Linux 64-bit Intel/AMD CPU, linked with musl libc
• aarch64-unknown-linux-gnu - Linux ARM64 CPUs (AWS Graviton, etc.)
• And more... (see --list-options for complete list)

Build Configurations

• pgo+lto - Profile guided optimization + Link-time optimization (fastest, recommended)
• pgo - Profile guided optimization only
• lto - Link-time optimization only
• noopt - Normal optimization
• debug - Debug build
• freethreaded - Free-threaded (PEP 703) build without GIL

Content Types

• install_only_stripped - Lightweight version with debug symbols removed (recommended)
• install_only - Only files needed for post-build installation
• full - All files and artifacts used in build (distributed as .tar.zst)
