METACRAN is a (somewhat integrated) collection of small services around the CRAN repository of R packages. It contains this website, a mirror at GitHub, a database with API, package search, database of package downloads (from the RStudio mirror), tools to check R packages on GitHub, etc.

See the menu on top for the complete list.

METACRAN is not a CRAN project. No METACRAN services use any of the CRAN mirrors or other CRAN infrastructure, other than downloading new and updated packages and other files.

METACRAN is not a separate R package repository. It contains exactly the same packages as CRAN itself.


Yes, please! METACRAN is developed completely in the open. All code and files are on Github at https://github.com/metacran .
