Vibe coding vs hiring an agency: what founders should know
Vibe code it yourself while you are testing the idea; bring in engineers when real users, payments or personal data are involved. Most founders end up doing both, in that order. This guide shows how to tell which stage you are at, and how to make the handover cheap.

The short answer
Vibe coding means building software by describing what you want to an AI tool and letting it write the code. It is a real way to get a working demo in days, and for many founders it is the right first step. Hiring an agency makes sense at a different moment: when strangers will use the product, pay through it or trust it with their data.
So the useful question is not "which is better?" but "which stage am I at?". The rest of this guide helps you answer that honestly, including the cases where you should not hire anyone yet.
What vibe coding is really good at
- Finding out whether the idea is worth building. A clickable version teaches you more in a week than a specification does in a month.
- Showing instead of telling. Investors, co-founders and first customers react to something they can use.
- Learning your own product. Building the first version yourself shows you which features matter and which you only imagined you needed.
- Internal tools with a handful of trusted users. If the people using it sit in the same room, most production risks do not apply.
None of this needs an agency. If you are at this stage, keep going on your own, and keep your money.
Where it runs out
AI builders optimise for a demo that works when its author clicks through it. The gaps appear in the parts a demo never exercises. They are well documented, and they are the same from project to project:
- Access rules. In a Supabase-based app, Row Level Security is what stops one user reading another user's data. Supabase tells developers to enable RLS on every table in an exposed schema; a table without it is readable and writable by any role with a grant on it.
- Secret keys. A Supabase secret key bypasses every Row Level Security policy and must never be in a browser. Prototypes often contain one anyway.
- Payments. Stripe states that you cannot rely on the checkout landing page alone to fulfil an order, and that webhooks are the reliable signal.
- Change without breakage. With no automated tests, every new prompt can quietly undo something that worked yesterday.
None of these is exotic. They are simply invisible until real users arrive, and then they are urgent. The full list of checks is in our prototype to production checklist, and we describe all eight common failure points on our page about how to fix a vibe coded app.
Decide by stage, not by preference
Find your row. The right choice changes as the stakes rise.
| Your stage | What is at risk | Sensible choice |
|---|---|---|
| Testing an idea | Only your time | Vibe code it yourself |
| Demo for investors or a pilot customer | Your credibility | Yourself, with a few hours of expert review before the meeting |
| First real users, no payments | Their data | Have the prototype audited and its security gaps fixed |
| Paying customers | Money and data, yours and theirs | Production build by engineers: yours or an agency's |
| Growing product, a team forming | Speed of every future change | Engineers with tests, reviews and a proper deployment process |
The hybrid path most founders end up on
The choice is rarely all or nothing. The pattern we see most is this: the founder builds the prototype, proves that people want it, and then brings in engineers to make it safe to run. The prototype is not wasted. The screens, the data model and above all the knowledge of what users actually do carry over.
Two things make that handover cheap instead of painful:
- Keep the code in a repository you control, not only inside the builder.
- Write down what the product must do in plain sentences, as you learn it. This list is worth more to an engineer than the code.
- Do not hand-build login or payments. Use the standard flows of an established provider from the start.
- Keep real customer data out until access rules have been checked by someone who knows how.
- Stop adding features once people want it. Every feature added to an unreviewed base is one more thing to repair.
If you are earlier than that, and the idea is clear but nothing is built, starting clean is often faster. That is what AI MVP development is for: a small first version, built properly, in weeks.
The costs that are not on the invoice
Comparing a builder subscription with an agency estimate compares the wrong things. Three other costs decide which route is cheaper for you:
- Your time. Weeks spent fighting a bug you do not understand are weeks not spent selling.
- The cost of a mistake. A leaked customer list or a payment that was never recorded costs trust, and in the EU a data leak can carry legal duties too.
- The cost of starting again. A prototype with no tests and no history gets harder to change with every feature, until rebuilding is the only option.
If none of these applies to you yet, you do not need an agency yet.
When you should not hire an agency
- You have not yet shown the idea to a single potential user.
- You cannot describe, in two sentences, who the product is for and what it lets them do.
- You expect an agency to find the business model for you. An agency builds; it cannot tell you what people will pay for.
- The product is a standard shop or a brochure site. Ready-made platforms do that better and cheaper.
When those are settled, a vibe coding agency gives you the speed of AI-written code with engineers accountable for the result. The first step is free: describe the product through our contact form, and you get a scope and an estimate within 24 hours.
