How do I get my vibe-coded prototype ready for real users?

A demo that works for you and a product that survives strangers are different animals: before launch you need real authentication, database rules, environment variables for secrets, error handling, and a deploy setup that separates test from production. Even Karpathy found that deploying his vibe-coded app was 'a painful slog' compared to the exhilarating prototype. Work through a production checklist, run the built-in security scans, and hand-walk every signup and payment path yourself before inviting users.

A quick orientation. The real value is below: resources worth your time, from people who've actually done it.
