Ten Checks to Stop Vibe-Coded Apps From Breaking Outside the Demo

A demo working on one machine does not mean an app is production-ready, since failures often appear on other laptops, with unusual input, or after a restart. The article recommends ten checks, starting with a fresh clone and clean install to expose hidden local dependencies. It also covers keeping secrets out of code, adding timeouts to outbound calls, validating inputs, and waiting for databases to be ready before starting services. Migrations should run once as a separate step rather than on every startup, and health checks should confirm real service functionality. Finally, generated files should be edited at their source, and failures should produce clear, locatable log messages.
