That doesn't make it useless, just misleading.
Edit - I guess I should be clear, this was a short rant about the term "serverless", not the product itself, which looks quite nice for static sites.
I don't necessarily agree. The most popular usage of "serverless" is as a label for things like AWS Lambda.
Again, in that situation, there is a server, but it requires zero configuration by the user. This product has the same pros/cons.
