Vibe coding a website – what it means, when to build with AI and when not to

"Vibe coding" has gone from an in-joke among developers to how a growing share of websites actually get made: you describe what you want, an AI builds it. If you are about to commission or build a website, it is neither a saviour nor a threat – it is a tool that fits perfectly in some situations and badly in others. The problem is that the marketing around the tools rarely tells you which situation is which.

This guide is not a comparison of individual tools. It is a decision framework for vibe coding a website: what should the website do for your company, how long should it live, and who owns the result when you want to move on? We recommend an AI builder when it fits, Webflow when that fits and a coded website with a headless CMS when that fits. The platform should match the need – not the other way round.

What is vibe coding – and why it matters to you as a buyer

Vibe coding is building a website or app by prompting an AI in natural language instead of designing or coding every part by hand. You describe "a landing page for a B2B service with pricing cards and a contact form", and the tool generates layout, text and sometimes working code. The term was originally coined for app development but is now used broadly for all AI-assisted building.

For a buyer, the most important insight is that two completely different kinds of tool are often lumped together under the same word. They solve different problems and have different consequences for ownership and SEO:

• AI-augmented no-code editors – tools such as Webflow AI and Framer AI. Here the AI adds a layer on top of a visual editor: it suggests sections and text, but you still build within the platform's framework and CMS. You get no code out – you rent the tool.
• AI-native code generators – tools such as Lovable, Bolt and v0. Here the AI writes actual code (usually React) based on your prompts. The result is a real codebase you can in principle export and take with you, but you need more technical understanding to maintain it.

The difference matters later in this guide: it determines both how the website behaves in search and what you actually own when you want to switch. It is the same basic question as in Build or buy a new website in 2026, just one step further down the chain – not only build or buy, but what you build with.

The first 80% goes fast – the last 20 decide

AI tools are genuinely good at the first 80 per cent of a website. A good-looking home page, a sensible structure, readable text and a contact form can be ready in an afternoon. For many projects that is exactly what is needed, and then an AI tool is the right answer.

The last 20 per cent is another matter. That is where a website stops being a nice surface and starts doing business: conversion logic that actually persuades visitors to get in touch, SEO that makes the page rank, performance that holds up under real traffic, accessibility, tracking, and a content system you can keep building on for years. That last 20 per cent is often dull, invisible to the untrained eye and hard to prompt your way to – and it is what decides whether the investment pays for itself.

This is not a criticism of the AI tools – just a realistic expectation. The question to ask is: does your project belong to the 80 per cent where a fast, good-looking build is enough – or does the business stand or fall with the last 20?

In most cases – whether you build the website yourself in Lovable or get help – the website strategy deserves some real attention. We can help you with that, even if you want to build and maintain the website yourselves!

The decision question: what should the website actually do for your company?

Before you choose a platform, have a more honest conversation about purpose. Most wrong choices start with picking the tool before the goal. Three questions decide most of it:

• What is the website's job? Should it validate an idea and look professional, or should it, over time, bring in enquiries, rank for high-intent keywords and convert traffic into business?
• How long does it need to last? A campaign page for a launch has a different lifespan from the company's primary website, which should carry the brand for five years.
• How much content should it handle? A website with five subpages is something completely different from one that needs to publish blog posts, case studies and landing pages on an ongoing basis.

The answers usually point clearly in one direction. The more the website needs to grow, rank and convert over a long time, the stronger the case for a structure built for that – and this is where professional help is usually needed. The more it needs to validate something quickly and cheaply, the stronger the case for an AI builder.

Decision map: choose by situation, not trend

The whole line of reasoning can be captured in a simple grid. Imagine two axes. One is the business goal: from validating and testing an idea at one end, to growing, converting and ranking at the other. The other is lifespan and ownership ambition: from short-lived and easy to migrate, to long-lived with high demands on owning the result yourself.

Add a third, overriding condition: does the website need its own app logic – login, database, payments, user accounts? If so, it leans towards an AI-native code generator or a fully coded solution wherever you land on the other axes, because traditional no-code builders do not handle that kind of functionality well.

Translated roughly into a choice of platform: validation + short lifespan points to an AI builder. Growth, rankings and a long lifespan point to Webflow or a coded website. And as soon as app logic enters the picture, the whole decision shifts towards code. The rest of the guide looks at each case in turn.

When an AI builder is the right choice – and what to keep in mind

An AI builder such as Lovable or Framer AI is often the right choice when speed and low cost matter most and the page's job is limited. Concrete situations where we think these tools fit:

• Validation and MVP. You want to test whether an idea, a pitch or a product gains traction before you invest in a real website.
• Campaign and event pages with a short lifespan, where the page will be replaced in a few months anyway.
• Early-stage startups that need something that looks professional for little money, fully aware that they will rebuild when the company matures.
• Internal tools and simple prototypes where search and conversion do not matter.

Keep two things in mind. First: brand uniqueness takes active work. AI builders are trained on similar patterns and therefore often converge on the same look – the same section order, the same kind of hero, the same cards. The pattern is well known: without deliberate direction the result is competent but generic, and it shows when ten companies in the same industry look the same. Second: be honest with yourself – the MVP often sticks around longer than planned. When it does, you will want to have chosen a tool you can move away from – more on that below.

When Webflow is the right choice

Webflow is one of our two first choices for a website that needs to last, market a company and rank in search. It is the right choice when you want pixel-level control over the design, a proper editorial CMS and the ability for non-technical people to edit content visually – without compromising technical SEO.

• Marketing websites where design, brand and conversion matter and the content will keep growing.
• Teams that want to own their content publishing themselves, with a CMS for the blog, case studies and landing pages.
• Projects where fast delivery and visual editing matter more than custom integrations or extreme performance.

The difference from an AI builder is not that Webflow looks better – it is that the structure holds. You get clean markup, a CMS that scales, and full control over – and a sound structure for – the technical SEO details that AI builders often skip. Webflow is not our default answer to everything, though; when performance, scalability or custom integrations matter most, a coded solution is often the better choice. Read more about how we work with the platform in choosing a Webflow agency.

When a coded website with a headless CMS is the right choice

A coded website on Next.js or Astro with a headless CMS is our other first choice – on a par with Webflow. It is the right choice when performance, scalability or custom integrations are decisive, or when the website needs to share content with channels beyond the web (apps, systems, AI). AI-assisted development has made this route considerably more efficient than it was even a year ago, which makes it a realistic option for more organisations.

• High traffic and strict performance requirements, where every hundredth of a second in page speed counts.
• Custom integrations and business logic that need to connect to internal systems.
• Content that will be used in more places than the website – that is the whole point of headless: the content is decoupled and served via API to several frontends.
• Complex design – coded websites give you the freedom to produce very complex design and animations efficiently.
• AI updates – if you want to be able to prompt changes to the website, we deliver our coded websites with context files that tell the AI how updates should be made, your tone of voice, SEO strategy, design rules and more. The classic "drag and drop" editor has become "prompt and sit back"!

This is also where vibe coding reaches its most serious form. AI-native code generators and AI-assisted development in a real codebase are related – the difference is how much technical direction and architecture lies behind them. We have written more about how it works in practice in AI-assisted web development with Claude Code and Next.js.

What happens to SEO when you build with AI?

Here are a few principles that hold whichever AI tool is popular right now. They are not about individual products but about how search engines and AI answer engines see what gets built.

Client-rendered JavaScript needs extra work to become crawlable. Many AI-generated websites are rendered in the browser (client-side rendering): the server sends what is essentially an empty page and JavaScript draws the content afterwards. Search engines can handle that, but it requires an extra rendering step and works unevenly – and AI answer engines often fetch content without running JavaScript at all. Server rendering and statically generated pages are more robust. The category is moving that way – Lovable, for example, made server-side rendering the default for new projects in May 2026. Take that as a sign that the tools are maturing, not as a guarantee that your particular page renders correctly.

Without a proper editorial CMS it is hard to scale content. A page that has been prompted into existence often lacks a structured content system. That works for five static subpages, but as soon as you want to run a blog, publish case studies and build topical authority, you need a CMS that handles many entries, categories and templates. It is one of the most common limitations when an MVP needs to grow.

So when SEO fails on an AI-built website, it is rarely because of a single bug; it is because the invisible foundations are missing. If your new website is not showing up, the causes are usually the same ones we go through in Website not showing on Google? The 10 most common causes – and several of them are directly linked to how the website is built.

The ownership question: do you own the code or rent a tool?

A question that is rarely asked until it is too late: what do you actually own when you want to move on? It determines how easily you can change agency, platform or supplier – and therefore how strong your negotiating position is.

• AI-native code generators such as Lovable export a real codebase (React). It is in principle portable: you can take it with you, let a developer maintain it and move it on. You own something concrete.
• Traditional builders offer no meaningful export. Content and design are often locked into the platform, and in practice a migration usually means rebuilding from scratch. It is one of several reasons why we advise against them for serious, long-lived websites.
• Webflow sits in between – you own your content and can export code, but the website is built to live in Webflow.
• Headless/coded gives the highest degree of ownership: the codebase and content are yours.

Ownership is directly linked to cost over time. A low monthly fee can hide a high lock-in cost on the day you want to move. That is why the real cost of a website should be calculated over several years, not on the first month's price tag – we have done the sums in How much does a professional website cost in 2026?.

Conclusion: match the tool to the situation

Vibe coding is neither a fad nor a universal answer. AI builders are genuinely the right choice for the right situation – they solve the first 80 per cent quickly and cheaply. But the last 20 per cent, the part that decides whether the website ranks, converts and can be built on, still requires deliberate choices about platform, structure, SEO and ownership.

Our position is simple: choose by situation, not trend. An AI builder when you need to validate quickly. Webflow or a coded website with a headless CMS when the website needs to carry the business over time. And stay away from platforms you cannot get out of. What makes the difference is rarely the tool itself but whether the choice matches what the website actually needs to do.
