We even have country arrangements-if you are a student, teacher or academic researcher in Egypt, you have free Mathematica-that’s about 40 million people right there. Most good universities have site licenses, so any student or faculty can use the technology unrestricted without personal fees. On top of that, one has to remember that the full tech stack is free at the point of use to millions of people thanks to their institutions’ support. So it’s not the “free to do anything” of open-source software, but it is free in many cases. Want to run it on a PC? Then there is the Wolfram Engine for macOS, Windows or Linux, free during the development phase of your project, or Wolfram Player, free for running code only but not for writing new code. The complete Wolfram Language runs on the $5 computer for free with some commercial use restrictions. Prefer local? Try the Raspberry Pi version. True, there are some memory, CPU time and storage limits as it costs us money when you use the free cloud, and you can pay to upgrade those. You have access to the whole language, through a browser or via APIs, for free.

The easiest way is to create a free Wolfram Cloud account. Of course, Wolfram|Alpha is free, but I mean the full Wolfram Language.

So if you can forgive the clickbait title, I thought I’d walk through them: Reflecting on that debate recently, I realized that most of the expected practical benefits of open-source software are also strongly apparent in Wolfram tech despite our non–open source approach. It generated some (mostly reasonable) debate about the benefits of different models. A couple of years ago, I wrote a piece outlining why I think that open source isn’t the right business model for Wolfram’s core tech.
