Is Vibe Coding Bad? An Honest Look at the Risks and the Hype

Ask the internet whether vibe coding is bad and you'll get two confident answers. One side says it's the end of the learning-to-code gatekeeping. The other says it's a security disaster waiting to happen.

Both are partly right, which is why the argument never ends. The honest answer is that vibe coding isn't good or bad. It's a tool, and the outcomes depend almost entirely on what you point it at and what you understand about the result.

What people are right to worry about

Most of the criticism is fair. It just applies to specific situations rather than the whole idea.

Security gets skipped

This is the big one. An AI will happily build an app that works perfectly in the preview and leaves every user's data readable by anyone who knows where to look.

It isn't that the AI is careless. It's that "works" and "is safe" are different tests, and only one of them is visible while you're building. A missing database rule produces no error and no warning. The app simply works, for everyone, including people who shouldn't be there.

The most common version of this involves Supabase and a missing Row Level Security policy. We walk through it in your Supabase database is probably public, and the Lovable security checklist covers the other usual suspects.

You can build something you can't maintain

If you never understood how the app works, you can't fix it when it breaks in a way the AI can't solve. You end up re-prompting, hoping, and spending credits. Eventually you have a project nobody can explain, including the AI.

The code can be messy

AI-generated code often works but isn't tidy. Duplicated logic, inconsistent patterns and unused files pile up. For a prototype that's fine. For something you'll maintain for years, it becomes a cost.

It gives false confidence

Seeing a polished interface appear in minutes can convince you the hard part is done. Usually it isn't. The unglamorous parts, like permissions, error handling, backups and payments, are where real products succeed or fail.

What people get wrong when they criticise it

"It's not real programming"

It produces real, running software. People are charging money for products built this way. Whether it counts as programming is a definitions argument, and the product either works or it doesn't.

"It will replace developers"

It changes the work, but the evidence so far is that understanding systems still matters a great deal. Tools that write code faster raise the value of people who can judge whether the code is right.

"Only beginners do it"

Experienced developers use AI heavily too. They just read and review the output, which is exactly the habit that makes it safer.

When vibe coding is a good idea

• Prototypes and experiments. Testing whether an idea has legs before investing in it.
• Personal tools. Software only you will use, where a bug costs you a minute.
• Internal tools with low stakes. A small dashboard for a team, with no sensitive data.
• Learning. Seeing working software appear is a fast way to build intuition.
• Landing pages and simple sites. Low risk, high reward.

When it's a bad idea

• Handling other people's sensitive data without understanding how it's protected. Health, financial or personal records need real care.
• Taking payments with code you haven't reviewed. Mistakes here cost money.
• Anything safety-critical. Obvious, but worth saying.
• Building a business on something you can't debug. Fine to start, risky to depend on.

How to make vibe coding safer

You don't have to give it up. You have to add the checks the AI doesn't.

1. Plan first. Know what data you store and who should see it. The practices that still work on day 30 start here.
2. Learn the basics of how your app fits together. Not syntax, just the shape: browser, server, database, permissions.
3. Test as a stranger. Open a private window, sign up as a new user, and try to see someone else's data.
4. Check your database rules before launch. If you use Supabase, turn on Row Level Security and write real policies.
5. Review changes in small steps. Big batches hide mistakes. Tools that show you diffs, like Cursor, help here, as we explain in Claude Code vs Cursor.
6. Run an automated scan. Our free security scan checks for common exposures in vibe-coded apps.

So, is it bad?

Vibe coding is neither a miracle nor a menace. It lowers the barrier to building dramatically, and it leaves the barrier to building well exactly where it was.

If you treat the AI's output as finished work, you'll eventually get burned. If you treat it as a very fast first draft that you're responsible for, it's one of the most useful shifts in how software gets made.

Frequently asked questions

Is vibe coding bad for beginners? No, it's a good way to start. The risk is skipping the fundamentals entirely, which catches up with you once the app grows or holds real data.

Is vibe coding dangerous? It can be, mainly because security problems are invisible in the preview. Checking your database permissions before launch removes most of the risk.

Is vibe-coded software secure? Not by default. It can be, if you check access rules, secrets and permissions yourself or with a scanner.

Will vibe coding replace programmers? It's changing the job, but understanding systems, reviewing code and making sound decisions still matter. Those skills are becoming more valuable, not less.

Is it ethical to ship an app I don't fully understand? If it holds other people's data or money, you have a responsibility to understand how it's protected. For personal projects, the stakes are yours alone.
