Ask HN: Is anyone running Mathematica/Wolfram Language in production?

I’ve been a huge fan of Mathematica as a tool for more than twenty years now, using it mostly for prototyping and analysis in notebooks. I’d love to be able to use it as part of a backend for a web app, but it’s unclear if this is even possible given Wolfram’s licensing restrictions. Has anyone here gone down that rabbit hole, or did you end up reimplementing things in an open language?
