That's not as good. Note that you didn't tell me the problem. If I hear this pitch, I'll think "I set up an envirovnment once, then never touch it again. Plus, I don't develop in the browser. So why do I care about this again?"

Note that patio11 specifically gives an example use case within the first sentence, so that I now connect to what this is useful for. And that is a use case I come across. Not sure I'd pay for this, but that's something.
