I've been seeing a few links to Strudel recently so I went digging to see how old the project is - looks like it launched in April 2022 https://loophole-letters.vercel.app/strudel
IIRC, that team are also (now) live-music-coding veterans, which in turn has informed how Strudel is built. It's not just a project that does stuff, it's a pretty well crafted instrument that is ideal for these performances.
As an engineer, I love letting the requirements shape the solution, but this is just on a whole other level.
Have you taken a look at how to install the Haskell variant? It's a full-on recipe, or a docker container. I'd take a desktop application over a website any day, but that was not on the menu. It was an SPA vs a devops exercise. Of course the SPA wins.
Edit: oh right! Also the toplap documentary from 2005 has some actual video of early live coding performances from this community. https://archive.org/details/toplap-documentary
