wolfram programming cloud
“The Wolfram Programming Cloud is an application of the Wolfram Language—specifically for programming, and for creating and deploying cloud-based programs.
How does it work? Well, you should try it out! It’s incredibly simple to get started. Just go to the Wolfram Programming Cloud in any web browser, log in, and press New. You’ll get what we call a notebook (yes, we invented those more than 25 years ago, for Mathematica). Then you just start typing code.”
