Vibe Coding Can Start a Prototype: Here Is How to Review the Result
Natural-language coding tools can produce a working-looking prototype quickly. The next job is understanding and checking what they created. Treat the result as software you are responsible for maintaining, especially when it handles accounts, files, data or paid services. Visual success is only one part of correctness.
Why it matters
Generated code can include assumptions you never requested. A prototype may use a temporary storage method, trust client-side input or leave a failure path unexplained. Review the main behaviour before adding more features.
A practical workflow
- Ask the tool to explain the project structure, data flow and important dependencies in plain language.
- Trace the main user journey and identify where data is stored, external services are called and access is checked.
- Test normal and invalid inputs, repeated submissions and unavailable dependencies using suitable sample data.
- Review important changes, secrets and deployment settings before exposing the app to real users or production information.
An example
A generated contact form may display a success message without actually delivering anything, or may expose a private key in browser code. Test the complete path from submission to the intended destination, then inspect how the implementation authenticates and handles failures.
A mistake to avoid
Do not keep asking for visual improvements while critical behaviour remains unverified. Also avoid running unexplained destructive commands suggested during troubleshooting. Preserve a recoverable version before making broad changes.
Try it and check the result
Have someone unfamiliar with the prototype complete the main task and deliberately make a mistake. You should understand the resulting behaviour well enough to explain, fix and verify it without relying on another unreviewed generation.
