What You Can Safely Vibe Code (and What You Can’t)

Some things are safe to vibe code on your own, some need a second pair of eyes, and some shouldn’t reach real users without an experienced developer. Sort your features before you build.

Risk levels: safe alone, needs review, needs a developer

What can you safely vibe code?

You can safely vibe code prototypes, landing pages, internal tools without sensitive data, and simple apps used by people who know it’s early. You need review for anything with user accounts or stored customer data. Payments, health or financial data, and anything regulated needs an experienced developer before real users rely on it.

What goes in each category?

Sort each feature by what a mistake would cost your customers and your company. The list below is a starting point for common features; your industry, your customers and the data you hold may move items up a level.

Why is AI-written code risky in these areas?

AI tools write code that works in the happy path but often misses security checks. Veracode’s 2025 study found AI tools failed to defend against cross-site scripting in 86% of relevant samples, and newer models weren’t more secure than older ones. The risks map to the OWASP Top 10.

How do you handle amber items?

Handle amber items by building them, then having someone who knows security check them before launch: login and access rules, database permissions, and where API keys are stored. A few hours of review is enough for most early apps. The checklist is on vibe coding security risks.

Founder rule

Red means stop and ask.

Payments, sensitive data and regulated work are where a single AI mistake becomes a business problem.

What about red items?

For red items, use established services instead of building your own, such as a payment provider’s hosted checkout, and have a developer implement and review the integration. If you are in a regulated industry, involve a developer and legal advice from the start. See vibe code or hire a developer.

Frequently asked questions

What is safe to vibe code?

Prototypes, landing pages, internal tools without sensitive data, and early apps used by people who know they’re early.

Can I vibe code user login?

Yes, but have access rules and database permissions reviewed before launch.

Can I vibe code payments?

Use a payment provider’s hosted checkout and have a developer implement and review it.

Is AI-generated code secure?

Often not by default. Veracode’s 2025 study found 45% of samples introduced OWASP Top 10 flaws.

What are the biggest risks?

Exposed API keys, missing database access rules, weak login checks and cross-site scripting.

Can I vibe code in a regulated industry?

Prototypes, yes. Anything handling real regulated data needs a developer and legal advice.
