What is Staging Environment?
A pre-production environment that mirrors your production setup (same infrastructure, same configuration, same data structure) where you can test changes before they reach real users. It catches the problems that only appear in production-like conditions: environment variable differences, database connection limits, and API rate limiting.

Why it matters
Without staging, every deploy is a gamble. You're testing in production, which means your users are your QA team. Staging catches broken migrations, misconfigured environment variables, and API changes before they affect real people.
Where AI gets this wrong
How AI tools get this wrong, and why it matters for your app.
AI tools don't set up staging environments. They generate code that works locally and assume it'll work the same way when deployed. The local-vs-production gap (environment variables, connection strings, API keys, rate limits) is where things silently break.
