Pipenv is almost exactly pip-tools + venv + a custom UI over the two. And slightly easier / more automatic venv management.

From the times I've looked at it (almost a year ago and older): pip-tools is / was the core of Pipenv... but it has been a fair distance ahead in terms of bug fixes and usable output for diagnosing conflicts. It seemed like pipenv forked from pip-tools a couple years prior, and didn't keep up.

Given that, I've been a happy user of v(irtual)env and pip-tools. Pipenv has remained on the "maybe some day, when it's better" side of things, since I think it does have potential.
