Posit offers something similar to Microsoft’s CRAN Time Machine, but it works not only for CRAN, but also for Bioconductor and PyPI. You can add a date to the Public Posit Package Manager URL to access a snapshot of all packages from that day.

For example: https://packagemanager.posit.co/cran/2025-03-02

You can browse available snapshot dates here: https://packagemanager.posit.co/client/#/repos/cran/setup?sn...

This also works for PyPI and Python packages: https://packagemanager.posit.co/pypi/2025-03-04/simple
