What is this website built with?

Paste a URL into the analyzer and the Overview card tells you when a site was made with one of 21 AI or no-code website builders. This page explains what that badge means, how the detection works and how to check a site yourself.

Analyze a website now to see its builder, tech stack, SEO audit and performance in one report.

How detection works

• The analyzer fetches the page and searches the raw HTML for each builder's public fingerprints: the hosting domains it publishes to (such as lovable.app or framerusercontent.com) and the value of the <meta name="generator"> tag that many builders write into the head.
• A match on any fingerprint reports the builder with high confidence. Phrases such as "powered by AI" with no builder fingerprint report "AI-assisted" with medium confidence and no name.
• Nothing is guessed from design, copy style or page structure. If the HTML does not reference the builder, the analyzer says nothing about it.

AI website builders we detect

• Lovable: Prompt-to-app builder that generates React front ends with Supabase back ends.

• v0: Vercel's generative UI tool that produces Next.js and shadcn/ui code from a prompt.
• Replit: Cloud IDE whose Agent builds and hosts full-stack apps on *.replit.app.
• Cursor: AI code editor; sites built in it are only detectable when they declare it.
• Windsurf: Codeium's AI editor; detectable only through a leftover generator tag.
• Durable: AI website builder for small service businesses that generates a site in about 30 seconds.
• 10Web: AI builder that generates a WordPress site with Elementor and hosts it on Google Cloud.

No-code website builders we detect

• Typedream: Notion-style website builder that publishes clean static pages from a document editor.

What it cannot detect

• A site on a custom domain whose owner removed every reference to the builder is not detected. This is common for code-generation tools such as Lovable or Bolt once a developer takes the code elsewhere.
• Editors such as Cursor and Windsurf produce ordinary code. They are only reported when a page explicitly declares them in a generator tag.
• Only the fetched page is inspected, usually the home page. A builder used for one landing page on a larger site will not show up when you analyze the home page.
• Detection is a statement about the HTML, not a judgement about quality. Several of these builders produce faster, better-structured pages than many hand-built sites.
