What your own AI prototype can give you
Vibe coding usually means building an application through natural-language instructions, with AI producing code and a person refining requests based on the result. The amount of human code review can vary substantially.
A prototype can help clarify screens, demonstrate an idea or try a workflow with test data. It gives you a more concrete picture of the product and a starting point for further decisions.
For a simple experiment, you can keep working independently if you understand its limits, can check the result and accept the consequences of a mistake.
When to involve a developer
Consider what the application does and how you verify its behaviour. The way code was produced does not by itself determine its quality. Design, review and maintainability matter.
- Real users: authentication, permissions and separation of data need checking.
- Payments and orders: mistakes can affect customers and downstream work.
- Connected services: outages, retries and delivery correctness need handling.
- Further development: changing one feature must not silently break another.
- Unclear operations: you do not know how to restore data, investigate an error or roll back a failed release.
If you cannot verify one of these areas, consider a technical assessment before expanding usage.
What working with a developer covers
The work includes clarifying requirements, designing data and integrations, checking failure cases and preparing operations. Generating code is one part of that process.
For an enquiry form, for example, I verify that the request is saved, reaches the intended recipient and displays confirmation. I also check invalid input, repeat submissions and unavailable external services.
Working with me includes an agreed scope, working previews and an explanation of next steps. Responsibilities and follow-up support are defined in advance. See my projects for my role in real applications.
How to compare the costs
For building it yourself, include tool subscriptions, your time, debugging and maintenance. For a supplier, compare the same scope: design, development, testing, deployment and handover.
Both approaches may involve hosting, databases, email and other service fees. Whether to continue a prototype or replace part of it depends on its actual condition.
A smaller first release can limit initial spending. It still needs to let users complete the core task you want to validate.
Five questions before launch
- Can I verify the main user task from start to finish?
- Do I know where the data lives and who can access it?
- Do I know what happens during an error or service outage?
- Can I deploy a change and return to a previous version?
- Have I agreed who handles problems and what normal operations cost?
This list supports a decision; it is not a complete audit. If an answer is missing, we can start by reviewing that area.
What if the application is already underway?
You do not need to decide on a full rewrite upfront. I first review the available code, services and core features. You receive findings, unverified areas and a recommended order of changes.
