Open source since 2009
Free software built by data scientists, for data scientists
Posit has invested in open-source data science since 2009. We build RStudio, the tidyverse, Shiny, Quarto, and 350+ packages used by millions of people every week. RStudio will remain free. Using RStudio without AI will cost nothing. Whether you're a student running your first regression or a team lead managing production models, the IDE is yours.
