"Production ready" isn't a feeling - it's a set of questions you can answer yes or no. Walk your app through the five areas below. Every honest "no" is a risk you're carrying into launch.
1. Security and access
- Can a logged-in user reach data that isn't theirs by editing an ID or URL?
- Is every input validated on the server, not just the browser?
- Are API keys and secrets kept out of the source code and separated by environment?
2. Data you can trust and recover
- Do you take backups - and have you actually restored one to prove it works?
- Does your data stay correct when two people act at the same time?
- Are the important rules enforced by the database, not just hoped for in the UI?
3. Behavior when things go wrong
- What happens when a third-party API is slow, rate-limited, or down?
- If a payment or multi-step action fails halfway, does the system end up in a sane state?
- Do users see a helpful message, or a blank screen?
4. Visibility in production
- If the app breaks right now, would you find out from your monitoring - or from a customer?
- Can you trace a reported problem to what actually happened?
- Do you have logging and alerts on the paths that matter most?
5. Scale, cost, and deployment
- Have you tested behavior under realistic load, not just a single user?
- Can one user - or a bot - run up your bill or exhaust a quota unchecked?
- Can you ship a fix safely and roll back if it goes wrong?
How to read your answers
If you answered "yes" and could prove it across all five areas, you're in good shape. If several answers were "no," "I think so," or "I don't know," your app demos well but isn't ready for the real world yet - and that gap is exactly where launches go sideways.
The good news: every item here is fixable, and most are far cheaper to address before launch than after an incident. If you want a second set of eyes, that's precisely what a scoped review is for.
