Perhaps OP's argument still applies to dev-oriented SaaS.
Are you as a dev still going to pay for analytics and dashboards that you could have propped up by Claude in 5 minutes instead?
The value proposition of SaaS is ultimately just that it's not a hack.
Most SaaS products could be replaced by a form + spreadsheet + email workflow, and the reason they aren't is that people don't want to be dealing with a hacky solution. Devs can hack together a nice little webapp instead of a network of spreadsheets, but it's still a hack. Factoring in AI assistance, perhaps SaaS is now competing with "something I hacked together in a week" as opposed to "something I hacked together in a month," but it's a hack either way.
I am absolutely going to pay for analytics and dashboards, because I don't want the operational concerns of my Elasticsearch analytics cluster getting in the way of the alarm that goes off when my primary database catches fire. Ops visibility is too important to be a hack, regardless of how quickly I could implement that hack.
Yes, because then I know the code is properly engineering, tested, maintained and supported.
Generating code is one part of software engineering is a small part of SaaS.
Analytics like what?! Sentry? See, i'm the first one to waste 15+ hours of my own time claude vibing some barely working analytics in order to save 15 dollars for not paying a proven solution to professionals who really understand that problem domain - but we all agree how dumb this is. But if i really can vibe code that analytics in 5 minutes, that thing was never a proven SaaS business in the first place and my use case with certainty a toy app with zero users..
