It’s really nice to have everything you need in one spot. Plus it’ll run on any OS and is free. I started learning how to program with C++ back in the early 2000s which required Windows and a Visual Studio license and it was still a pain to get stuff done. Whether it’s RStudio or Jupyter there’s really never been a better time to start picking up a language and building something useful. Three cheers for the creators, maintainers and community who support tools like this.
That pricing sheet is for Posit Workbench; RStudio Server[0] can host as many people as you have the compute for, and it's free and open source. It does only support one session per user, but might meet the needs of a small research group.
