RStudio Overview
RStudio Desktop is Posit's desktop IDE for R, Quarto, Shiny, notebooks, package development, and data science workflows. The verified links here use Posit's download1.rstudio.org host for RStudio 2026.05.0-218: Windows EXE, macOS DMG, and Ubuntu Jammy AMD64 DEB. RStudio requires a working R installation on the target machine. For offline deployment, download R and RStudio packages separately, keep the installers with checksum records, and install R before launching RStudio. Linux distributions use different package formats. The DEB listed here is the official Ubuntu package; administrators on RPM-based systems should use Posit's official download page or repository for the matching RPM build. The RStudio offline installer is the standalone setup distribution for Windows/macOS/Linux, with the full setup file suitable for offline deployment on developer workstations and CI/build machines that cannot reach the vendor's update servers during install.
