I've heard, investigated, but it's never passed my filter to a try state. I investigated a bunch of things in config space before and get bored because they are in dev bubbles. I was trying to find something viable for commercial purpose. My topic is only API and list just 2 things specialized in API work. It's pretty narrow scope. And the other reason I list just the two is that I know the web industry is quite irrational they only pick what big players back it or just for sake of jobs market reason. So honestly I'm not interested in CUE.
