Vibe coding, and the part after it

Vibe coding got you the prototype. This is the part where it becomes software you can run.

What it is

Vibe coding is building software by describing what you want in plain language and letting an AI write the code, then steering by conversation: “make the form two columns”, “the total is wrong when the cart is empty”. You read the result, you test it, you rarely type the code yourself.

Andrej Karpathy coined the phrase in February 2025 to describe exactly that mode: giving in to the vibes, forgetting the code exists, accepting changes without reading the diff (source). Simon Willison drew the useful line a month later: if you review and understand what the model wrote, that is AI-assisted programming; vibe coding is specifically the version where you don't (source).

What it is good at

• Getting from an idea to something you can click on in an afternoon.
• Exploring a design by building three versions instead of arguing about one.
• Letting people who know the problem, not the framework, produce a working first draft.

Where it breaks down

The failure modes are not about the prototype. They are about what happens after it works:

• Where the data lives. Most builders keep every customer's app in one shared database on the builder's own infrastructure.
• Who else can reach it. The same agent that wrote the app can rewrite it, and in some tools it can reach production data while doing so.
• Unreviewed security. By definition, vibe-coded code was not read. Logins, payments and anything that touches customer records need a human to read them before real users arrive.
• The way out. A prototype that only runs inside the tool that built it is a demo, not software.

Taking a vibe-coded prototype to production

1. Get the code out. If the tool cannot give you a repository or a ZIP, stop here and pick a tool that can. In the Builder, both are one click (export).
2. Put the data somewhere that is yours. A database on a server you control, not a row in a shared tenant. Cloud projects here run on a dedicated server with PostgreSQL installed on it (how).
3. Read the sensitive parts. Authentication, payments, anything that writes customer data. The staff-reviewer agent helps; it does not replace you.
4. Give it a domain and TLS. Register one or bring one; certificates are provisioned automatically.
5. Keep the exit open. Push to GitHub as you go, so leaving later is a decision, not a project.

Questions people ask

What is vibe coding?

Building software by describing what you want in plain language and letting an AI write the code, then steering by conversation instead of editing every line yourself. Andrej Karpathy coined the phrase in February 2025.

Do I need to know how to code?

Not to get started. You describe what you want and the Builder writes it. Every file it writes is yours to open and edit, and before anything reaches real users, you or someone you trust should read the parts that handle logins, payments and customer data.

What can I build with SeamAI Pro?

Full-stack web apps: dashboards, internal tools, SaaS products, customer portals and content sites. The browser workspace runs Vite + React + TypeScript; cloud projects add a Node backend and a PostgreSQL database on a dedicated server.

How is this different from other vibe coding tools?

The prototype part is similar. The difference is what happens after: cloud projects run on a dedicated server with their own PostgreSQL database and domain, and you can export the whole project as a ZIP or push it to GitHub at any time.

Which AI models are available?

Free accounts use a small, fast model from the starter catalog. Paid plans unlock the full catalog across Anthropic, Google and OpenAI. The auto mode picks a model for each task, or you choose one yourself.

Can I deploy what I build?

Yes. Every plan includes a hosted deployment on a free subdomain. Paid plans add dedicated cloud servers with their own PostgreSQL database and custom domains.
