AI Website Builders in 2026: The Complete Guide
2026-04-02
Each AI builder leaves distinct technical fingerprints — different CDN domains, DOM attributes, JavaScript globals, and HTTP headers. The detector matches these against a database of 80+ builders to identify the platform.

The Rise of Vibe Coding
A growing share of AI-built sites are not built with any platform at all. "Vibe coding" — building apps by describing what you want to an AI coding assistant and letting it write the code — is mainstream in 2026.
The typical vibe-coded stack:
Vibe-coded sites have no generator tag and no platform CDN. They look like custom-built sites because technically they are. The signal is in the code patterns: Tailwind utility classes, Supabase API calls, and React component structures that follow AI generation conventions.
AIWebsiteDetector.com assigns an AI probability score to these sites based on code structure analysis even when no specific platform is identified.

Frequently Asked Questions
Are AI-built websites good for SEO?
Yes — modern AI builders like Framer, Webflow, and Squarespace output clean, semantic HTML that performs well for SEO. Vibe-coded React apps can have SEO issues if rendered client-side only, but Next.js (the most common vibe-coding stack) handles server-side rendering by default. Content quality matters more than the builder choice.
Can I switch from one AI builder to another?
Switching usually requires rebuilding. Most AI builders use proprietary design systems that do not export cleanly to other platforms. Exception: vibe-coded sites are just code and can be migrated or modified freely. If portability matters, building with code (Bolt, Cursor) rather than a platform is the safer choice.
What is the difference between Lovable and Bolt?
Both are AI-first development environments but take different approaches. Lovable is more product-like — it manages your project, handles deployment, and abstracts the code unless you choose to see it. Bolt shows you the code from the start and runs a full Node.js environment in the browser. Developers typically prefer Bolt; non-developers find Lovable more approachable.
Can AI builders handle e-commerce?
Partially. Wix AI, Squarespace AI, and 10Web all include e-commerce capabilities. For serious e-commerce with large catalogs, complex fulfillment, or high transaction volume, Shopify remains the stronger platform — though AI tools can help build the Shopify storefront's design layer.
Is vibe coding replacing professional web development?
For certain use cases — MVPs, internal tools, landing pages, prototypes — yes, AI coding tools are replacing professional development for many teams. For complex, scalable systems with high performance requirements, professional development remains necessary. The boundary is shifting rapidly as AI capabilities improve.
