openslide-bin
Binary build of OpenSlide
Decision gist · record as of 2026-08-14
Yes, if you need OpenSlide and want to avoid system-level installation complexity. The package is actively maintained, has no known vulnerabilities, and is built by the OpenSlide maintainers themselves. Install friction is medium due to platform-specific wheels, but that's inherent to any binary distribution. Copyleft licensing (LGPL-2.1) requires compliance if you redistribute or modify; for internal use or linking via OpenSlide Python, this is typically not a barrier. Recommended for anyone using OpenSlide Python who prefers pip-based dependency management.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9+, pip 20.3+, and a supported platform (Linux glibc 2.28+, macOS 11+, or Windows 10+).
- OpenSlide Python ≥ 1.4.0 required to auto-detect openslide-bin.
- Medium install friction due to platform-specific wheels (aarch64, x86_64, macOS universal2, Windows x64).

What it is and what it does
openslide-bin packages the OpenSlide library—a C library for reading whole-slide microscopy images—as a pip-installable Python wheel. Instead of requiring users to install OpenSlide separately via their system package manager (which may be outdated or unavailable), this package bundles the latest OpenSlide binaries directly into the wheel, eliminating a common installation friction point.
When installed alongside OpenSlide Python ≥ 1.4.0, openslide-bin is automatically discovered and used. It ships the same binaries as the official OpenSlide website, has no additional runtime dependencies beyond what your system already provides, and supports Python 3.9+ on Linux (aarch64, x86_64 with glibc 2.28+), macOS 11+ (arm64, x86_64), and Windows 10+ (x64). The package is actively maintained by the OpenSlide project itself.
Use it for
- Deploy whole-slide image analysis pipelines in Docker or cloud environments without requiring system-level OpenSlide installation.
- Simplify CI/CD workflows for histopathology or medical imaging research by pinning OpenSlide version via pip.
- Develop cross-platform microscopy image processing tools that work on Linux, macOS, and Windows without platform-specific build steps.
- Use in research environments where system package manager access is restricted or versions are outdated.
- Bundle OpenSlide with Python applications distributed via PyPI without requiring end-users to install native libraries.
