OPENRNDR is amazing and I love using it for generative art, especially installations, not so much for stuff to share on the web. I find the API is way more tuned to my programmer brain compared to Processing/p5.js. The only problems, I think, are:

- It's Kotlin/JVM. Looks pretty, is ergonomic to write in, runs everywhere. But also, I feel forever chained to IntelliJ and cant wrap my head around the build system at all.

- Small community. Searching for issues, tutorials, or anything of that sort doesn't yield that many results. Not a problem if you're self-sufficient enough, but might stop me from recommending it to a beginner. The development also seems kind of slow.
