virtualenv is a tool for creating isolated virtual Python environments, allowing projects to have their own dependencies independent of the system Python. It is the reference implementation maintained by the Python Packaging Authority (PyPA).
Use cases
- create isolated python environments
- install project dependencies without polluting system python
- manage multiple python versions per project
- reproducible development environments
- separate dependency sets for different projects
When to choose
- you need environment isolation for Python projects
- you want a mature, PyPA-maintained tool with broad interpreter support (CPython, PyPy)
- you need faster environment creation than the built-in venv module
When to avoid
- you only need basic isolation and are fine with Python's built-in venv module
- you want full project/dependency management with lockfiles - consider poetry or uv instead
- you are managing non-Python language environments
