Chances are they aren't a technical person and didn't build it, so wouldn't have anything interesting to say anyways. Web compilers are dime-a-dozen and LLMs can easily produce them with no active guidance. Very much in the training data[1]. This looks like just another person posting something they spent all of two minutes prompting.

So, is there a reason that your link to the official playground is dramatically more underwhelming and lacking in features compared to the from-scratch-in-C Minikotlin compiler page? You claim that the submission is uninteresting work from a lone non-technical rando and then link to / implicitly endorse a "hello world" repo from the multi-billion dollar corporation that runs the whole thing?

The JetBrains team didn't feel like prompting for a Claude UI to go with their project they wrote by hand 8 years ago, I suppose. Are you really that impressed with stock LLM-generated UI?

Note the JetBrains playground includes features that are actually useful for a code playground, letting you configure compiler version and flags, which is likely more relevant than a faux-IDE UI for the use cases people use playgrounds for. It also supports importing packages, while this doesn't. This doesn't seem like a human even attempted to use it for anything, otherwise they would have realised how lacking it is. Unfortunately it seems like people who prompt slop can't be bothered to dogfood it... or maybe pigfood it?

"From scratch in C" means literally nothing here. LLMs can output C too. It may or may not be safe, efficient C, but writing C that compiles is trivial. Prompting "write it in C" poses no greater difficulty than any other language.

The Kotlin/WASM work is in the main repo. This submission has no source code and barely any technical detail.

”Web compilers are dime-a-dozen”

Oh didn’t know that! What is the best for ”compiles to wasm in browser” featureset?
