You are selling a framework, not an application, so why in the world are you comparing yourself to a SaaS which means literally "software as a service", which you are not. No one is going to pay for your "framework", less of all developers.

Sounds like they're aiming for PaaS with a proprietary framework? Works for fly.io and others - and if they found a growing niche and are targeting it well... I can picture some of the same techniques that work for B2B SaaS work there.
