Here's a browser-based live coding environment I've built called Facet which connects to Max/MSP:
Ever since the initial release of Facet v0.1.0 in May 2021, I've done all my generative audio work (~50GB total) with it. Of course it's not perfect, but I think it's a nice balance of powerful / flexible! If anyone does use it, I would love any feedback / questions / suggestions!
I'm currently working on an update with a whole bunch of improvements.
