There are similar tools to this but this is nothing like Lambda or CF Workers. Lambda doesn't do anything remotely close to generating frontend UX for a script.
Ah. I wasn't able to figure that out from the homepage, the first docs page, or the "getting started" link in the docs. Homepage has nothing, and the first two docs pages I looked at made it seem like some MVP lambda-alike.
Thanks for this feedback! We know our website is pretty barebones right now, but working on putting more info there. We'll also work on making this clearer on our docs!
