Frequently Asked Questions
What is a website tech stack detector?
A website tech stack detector analyzes the code, scripts, and infrastructure of any website to identify what platform, CMS, or framework it is built with. AI Website Detector scans 80+ signals including JavaScript libraries, CDN domains, HTML attributes, and HTTP headers.
How accurate is the detection?
Our detection engine achieves over 95% accuracy on major platforms by cross-referencing multiple independent signals. Some websites actively hide their stack, which can reduce confidence — we always show a confidence level alongside the verdict.

We detect 80+ platforms including Framer, Webflow, WordPress, Shopify, Lovable, Bolt, Durable, Wix AI, 10Web, Squarespace, Ghost, Mixo, Gamma, Typedream, Hostinger AI Builder, and many more.
Is this tool free?
Yes. AI Website Detector is completely free to use with no account required. Just paste any URL and get instant results.
What is AI probability?
AI probability is a score from 0% to 100% that estimates the likelihood a website was built using an AI-powered tool or platform. AI-native builders like Framer, Lovable, or Bolt score high. Traditional hand-coded or CMS sites score low.
