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.
