I would say the compiler explorer[0] fits the definition perfectly. It may seem like a straightforward piece of software, but it has immensely changed the way people discuss and share knowledge around compilers and performance optimization. I regularly feel the impact on the quality of forum discussions. There's a lot less speculation about if "call X gets inlined", or "Y gets vectorized". Bold claims can be supported or disproven quickly by sharing a link. And then you have tools like llvm-mca[1] or uiCA[2], if you don't mind going into the weeds.

along those lines, the entire notion of a web playground (a sandbox where users can just write and execute or otherwise process code) has vastly reduced the barrier for checking out a project or experimenting with its behaviour

  > web playground This _so_ much. Where in the past I've used Jupyter Notebooks for short, one off stuff or to test something, I now do that online for almost any language. Notebooks are still useful to write documentation though.

    Well, Notebooks main use case is a different purpose, not for trying one-off stuff or checking if some syntax is valid. It's for doing stuff step by step, annotating the steps and/or explaining each result. Web playgrounds are ok for testing some syntax (if you don't have a local REPL/easy way to test), but not for one-off stuff that involves file input or that you want to check against real environment assets.

    I was thinking about including Mathematica as enlightenmentware. Mathematica 6 (https://www.wolfram.com/mathematica/newin6/ https://www.wolfram.com/mathematica/newin6/) was the first truly interactive system I used (we happen to have a box with a license at the university). It impressed me so much that I still have a lot of warm fuzzy feelings toward Stephen Wolfram and his work. Unfortunately, my relationship with Mathematica didn’t go anywhere: It was too expensive back then, and I never found a good use for it except for double-checking my homework. I tried other computer algebra systems, but they didn’t impress me as much. If you own a Mathematica license and found a good application for it, please let me know!

Pahole is a related utility for high performance programmers. I've been able to attain orders-of-magnitude performance improvements in trading applications using it.
