(founder here) we do have a vscode plugin (that handles the "follow me" side of "I click on something in the design" as well as triggering updates on the canvas, but it's not a VScode plugin _of_ Utopia. The monetisation isn't the big issue, it's more around performance management (and candidly also the internal dev cycle). We don't believe single-player use should be monetised anyway, that just creates the wrong incentives for us.
I think it is: https://github.com/concrete-utopia/utopia#build-editor-vscod...
