Description:
Seamless operability between C++11 and Python

Type: Formula | Latest Version: 3.0.1@0 | Tracked Since: Oct 10, 2025

Links: Homepage | formulae.brew.sh

Category: Developer tools

Tags: c++ python bindings header-only development

Install: brew install pybind11

About:
pybind11 is a lightweight header-only library that exposes C++ types in Python and vice versa, mainly for creating Python bindings of existing C++ code. It uses a C++11-compatible macro-based interface that automatically generates the boilerplate code needed to interface with Python's C API. Its main value proposition is enabling seamless interoperability for performance-critical code.

Key Features:

Header-only library requiring no compilation
Supports modern C++11 features including lambdas and move semantics
Minimal boilerplate compared to other binding tools like Boost.Python

Use Cases:

Creating Python bindings for existing C++ libraries
Exposing performance-critical C++ code to Python for optimization

Alternatives:

Cython – Cython uses a Python-like language and requires a compilation step, while pybind11 uses pure C++ macros
Boost.Python – Boost.Python is more heavyweight with extensive dependencies, while pybind11 is lightweight and header-only
