tox-uv is a tox plugin which replaces virtualenv and pip with uv your tox environments. Note that you will get both the benefits (performance) or downsides (bugs) of uv.
Install tox-uv into the environment of your tox and will replace virtualenv and pip for all runs:
python -m pip install tox tox-uv
python -m tox r -e py312 # will use uvuv-venv-runneris the ID for the tox environments runner.uv-venv-pep-517is the ID for the PEP-517 packaging environment.uv-venv-cmd-builderis the ID for the external cmd builder.
This flag, set on a tox environment level, controls if the created virtual environment injects pip/setuptools/wheel into
the created virtual environment or not. By default, is off. You will need to set this if you have a project that uses
the old legacy editable mode, or your project does not support the pyprooject.toml powered isolated build model.
