Curious what you think of https://github.com/pipevals/pipevals (author)

I have never heard of this! I took a quick look. I think I'm definitely not in the right audience for a tool like this, as I am more comfortable just writing code. But I think putting a UI over things like this _forces_ the underlying system to be more declarative...

So in practice I imagine you get at a lot of the same ideas / benefits!
