I would have been probably less irritated by something simple like "current serverless solutions". But I'm not a web developer and don't understand the differentiation details you mention, so I'm not in the target demographic here. From my outsider's perspective, serverless is something that just recently came into mainstream usage. People who this product is made for probably see this differently and thus wouldn't have a problem with the formulation. Language pedantry aside, good luck with your product launch :)
