In short: with AI builders such as Lovable, Bolt, v0 and Wix AI you can produce a good-looking website in an afternoon in 2026. For a test, a freelancer or a campaign that is enough. Once customers have to find you, trust you and convert, AI sites hit the wall on ownership, SEO, speed, accessibility and security. Over 3 years a well-built site is often cheaper than a subscription plus your own hours.
What AI builders genuinely do well in 2026
Let us be honest about where AI tools are strong, because it is more than agencies like to admit:
- From idea to something tangible. One prompt, 5 minutes of waiting and there is a homepage with copy, images and sections. For validating a proposition that is worth its weight in gold.
- Price. Wix, Squarespace and Framer charge €15 to €50 per month. Lovable and Bolt run on credits from about €20 to €25 per month. No quote, no waiting.
- Standard work. Contact form, pricing table, FAQ, team section: all in seconds and without a typo.
- Iteration. 'Make the header darker and move the button left': done within a minute. That is faster than any designer.
- Prototypes for agencies and startups. More and more startups come to us with a Lovable prototype as the brief. That works better than a 20-page document.
For a freelancer with 1 service, an event page or a landing page to test an idea, an AI builder is a sensible choice in 2026. The question is what happens when the site has to perform.
Where it goes wrong
Ownership and export
Wix, Squarespace and Framer do not give you code. Stop paying and the site is gone. Lovable and Bolt do give you code (React, usually with Supabase), but someone has to host, update and understand that code. Ask yourself: could someone else maintain this site in 2 years? With a closed builder the answer is no.
SEO
AI builders produce tidy titles and meta descriptions, but SEO lives in structure: which pages, which keywords per page, internal links, schema.org, site speed and a content plan. A generated site has 1 homepage with everything on it and no strategy. What you miss on SEO only shows after 6 months, when the leads fail to arrive.
Speed
Generated front ends often drag along 500 kB to 2 MB of JavaScript. Google measures Core Web Vitals (LCP under 2.5 seconds, INP under 200 milliseconds) and uses them as a ranking factor. A mobile Lighthouse score of 50 is the rule rather than the exception for AI sites.
Accessibility
Since June 28, 2025 the European Accessibility Act applies to companies that sell online and have 10 or more employees or more than €2 million in revenue. AI-generated HTML scores poorly on contrast, heading structure, form labels and keyboard operation. What the law actually requires is explained in the European Accessibility Act for websites.
Security
The biggest risk sits in apps with a database. In 2025 research into 1,645 apps built with Lovable found that 170 of them leaked personal data because the access rules on the database (Supabase Row Level Security) were missing; it was assigned CVE-2025-48757. The tool has improved since, but the principle stands: if you do not understand the code, you cannot judge its security.
Technical debt
An AI builder optimizes for 'it works now'. After 30 iterations you have a codebase with duplicate components, unclear dependencies and no tests. Every next change takes longer, until rebuilding is cheaper than continuing. For most AI sites that moment arrives between month 6 and 18.
Cost comparison over 3 years
| Option | Year 1 | Years 2–3 | Total 3 years (excl. VAT) | What you are left with |
|---|---|---|---|---|
| Wix or Squarespace, built yourself | €400 subscription plus 40 hours of your time (€2,000 at €50 per hour) | €800 plus 20 hours (€1,000) | €4,200 | Nothing: no code, no export |
| Lovable or Bolt with Supabase, built yourself | €600 credits, €300 hosting, 60 hours (€3,000) | €1,800 plus 40 hours (€2,000) | €7,700 | Code someone has to maintain |
| Freelancer, WordPress template | €3,500 build plus €600 hosting and maintenance | €1,200 | €5,300 | Site and code yours, plugin maintenance |
| Studio such as RABZI, custom Next.js | €4,950 build plus €1,140 maintenance | €2,280 | €8,370 | A fast, findable, accessible site that is yours |
| Traditional agency | €9,000 build plus €2,400 maintenance | €4,800 | €16,200 | The same result as the studio, with an account manager |
The AI builder wins on cash in year 1 and loses as soon as you count your own hours honestly and the site has to deliver something. What a professional site costs and what drives it is covered in how much a website costs.
How RABZI uses AI the right way
We are not an agency that rejects AI. Every RABZI project is made by 1 senior maker who designs, builds and handles SEO, accelerated by Claude Code for the repetitive work: scaffolding components, generating variants, writing tests, structuring content, checking accessibility. The difference from an AI builder is who is at the helm.
- The strategy is human. Audience, keywords, site structure and conversion path come from a conversation with you, not from a prompt.
- The code is reviewed. Everything AI generates is read, tested and rewritten where needed by a senior. Security, speed and accessibility are requirements, not hopes.
- The design is yours. Not a template shared with 10,000 others, but a design system built on your brand.
- You pay a studio price for agency quality. Because AI speeds up the manual work, a custom website with us starts at €4,950 instead of €9,000 to €15,000, and goes live in 3 to 6 weeks.
Marketing agencies use us the same way: they handle strategy and campaigns, we build white-label what an AI builder cannot handle.
Decision tree: when to use an AI builder, when an agency
Answer these 5 questions:
- Does the site have to win customers through Google? No: AI builder. Yes: continue.
- Do you sell online or fall under the accessibility act? Yes: agency or studio.
- Do you process customer data behind a login? Yes: have the security built or reviewed by a professional.
- Do you want to use and expand the site for more than 1 year? Yes: make sure you own the code in a mainstream stack.
- Is your own hourly rate above €50? Yes: count your own hours, and outsourcing is usually cheaper.
Two times 'no' on the first two questions: build it yourself with AI and come back when it grows. Otherwise: have it built, if you like with your AI prototype as the brief.
From AI prototype to production: the migration path
An AI prototype is a fine starting point, not an end point. This is how we take a site from Lovable, Bolt or Wix to production:
- Audit (1 day). Structure, content, SEO potential, speed, accessibility and security of the prototype. What stays, what goes.
- Strategy (week 1). Keywords, site structure, conversion path. The prototype becomes the brief.
- Rebuild in Next.js (weeks 2–4). Components rebuilt, design system, CMS for your copy, Core Web Vitals in the green.
- Data and forms (week 4). Migrate existing submissions, accounts or content, connect CRM or newsletter.
- Launch with redirects (week 5). Forward old URLs, Search Console, monitoring, handover.
The result: the look you already liked in the prototype, but fast, findable, accessible and yours. Which foundation suits that best is compared in Next.js vs WordPress.
RABZI estimate: a website from RABZI starts at €4,950 excl. VAT (Launch: up to 8 pages, live in 3 to 6 weeks), from €9,500 for Growth (up to 20 pages, design system, NL/EN) and from €19,500 for Flagship. If you already have an AI prototype we use it as the brief, which saves time in the design phase. See websites and web design or the full pricing.
Frequently asked questions
Can you make a good website with AI? Yes, for a simple site without SEO ambitions: a landing page, a portfolio, an event page. For a site that has to win customers through Google, comply with the accessibility act or process customer data, you need a senior who reviews strategy, code and security.
What are the downsides of an AI website? No or limited ownership of the code, little SEO structure, slow front ends, poor accessibility, security risks with databases and technical debt that forces a rebuild after 6 to 18 months. With closed builders you also get a subscription that never ends.
Is Lovable suitable for a business website? As a prototype or a first version for a startup: yes. As a production site with customer data: only if a developer takes over security, hosting and maintenance. Lovable hands you code, which is a big advantage over Wix or Squarespace, but someone has to manage that code.
Does RABZI use AI to build websites? Yes. A senior maker uses Claude Code for repetitive work: components, variants, tests and checks. That makes a custom site with us cheaper and faster than a traditional agency, while strategy, design, security and quality are decided and checked by a human.
Conclusion
Building a website with AI is a good choice in 2026 for a test, a simple site or a prototype. Once the site has to win customers, comply with legislation or process data, a studio that uses AI with a senior at the helm wins: faster and cheaper than a traditional agency, with a result that is yours.
