The Gap Between Vibe Coding and Production Reality

A non-programmer spent a month building a SaaS using Claude, only to realize upon getting real users that production environments demand permissions and isolation, not just a slick UI.
Stumped by a friend's question—"Can User A change their ID to view User B's data?"—the author realized they had split auth, database rules, and server functions across isolated Claude chats, effectively assembling a system on a "one prompt, one permission" basis. The accompanying image reinforces this: vibe coding only covers surface prototyping, while production reality requires heavy engineering for auth, access control, data integrity, logging, rate limiting, CI/CD, rollbacks, monitoring, and disaster recovery.
The author concludes by asking no-code/low-code founders what they actually audit before real users touch customer data.
