Pex is a tool and library for generating .pex (Python EXecutable) files - self-contained executable Python environments similar to virtualenvs - as well as lock files and venvs. It simplifies deploying Python applications so they can be run anywhere with a simple copy, even across Linux and macOS via bundled platform-specific distributions.

Use cases

• package a python app into a single executable file
• deploy python applications to production without pip install
• create lock files for reproducible python environments
• run a script with dependencies in an ephemeral environment
• build a portable python environment that works on linux and mac
• freeze a virtualenv into a runnable artifact
• run python tools like sphinx without installing them

When to choose

• you need to deploy Python applications as single-file executables
• you want reproducible, locked dependency environments for deployment
• you need cross-platform portable Python environments
• you use build systems like Pants that integrate with PEX

When to avoid

• you only need local development virtualenvs without deployment needs
• you need standalone binaries that bundle a Python interpreter for non-Python users
• you are packaging GUI desktop applications
