AI Website Insights: May 2026
In May 2026, AI Website Detector scanned 3,562 unique websites and classified each one based on the technology stack, signals, and fingerprints detected in its code. Of those, 1,505 (42%) showed clear evidence of AI involvement — either through an AI website builder platform or AI-assisted development practices.
Compared to Apr 2026, total scan volume increased by 941 websites. AI adoption grew by 2 percentage points, continuing the upward trend in AI-powered web development.
Next.js remained the most commonly detected technology this month, appearing on 577 scanned websites — representing 29% of all builder detections.

Platform Analysis
Next.js led all detected technologies in May 2026 with 577 sites — a 29% share of all builder detections. Its continued dominance is driven by an enormous plugin ecosystem, hosting availability, and a massive global install base that compounds monthly.
WordPress ranked second with 283 sites (14%). Both platforms represent traditional development approaches, suggesting AI adoption, while real, is still concentrated in specific segments.
A notable signal: Lovable entered the top 3 with 195 detections — a strong showing for an AI-native builder platform and an indicator of accelerating mainstream adoption beyond early adopters.
AI Builder Spotlight
9 AI-native builder platforms appeared in this month's detections, collectively powering 290 websites (15% of all detected builder sites).
Lovable led the AI-native category with 195 sites. Framer followed with 42, and Webflow with 28. These platforms are winning new site creation — particularly from non-technical founders, solopreneurs, and small businesses who need a production website without a developer.
AI-native builders: sites created using AI website builder platforms that generate design, layout, and code from prompts or AI-driven configuration — not traditional hand-coded or CMS-based deployments.
What This Trend Suggests
AI involvement in detected websites rose by 2 percentage points month-over-month — from 40% in Apr 2026 to 42% this month. If this trajectory holds, AI-influenced sites could cross the majority mark in the coming months.
The growth is primarily driven by the AI-assisted category rather than fully AI-native builds. This suggests developers are adopting AI coding tools faster than businesses are migrating to full AI website builders — a bottom-up adoption pattern, not top-down.
For developers and businesses choosing a tech stack today: the data shows AI tools are becoming the default, not the exception. Whether through AI website builders for rapid deployment or AI coding assistants for custom builds, the question is no longer if AI is part of your workflow — it's which tool fits your use case.
What This Data Shows
Every website in this report was scanned by real users of AI Website Detector — people actively investigating tech stacks of live production websites. This makes the dataset uniquely biased toward websites that are being researched, which tends to skew toward higher-traffic or professionally built sites.
The 42% AI involvement figure means that a significant and growing share of websites show detectable AI involvement. AI-native builds (6%) are sites deployed via platforms like Framer, Webflow, Lovable, or Durable — tools where AI generates the site structure, design, and often the copy. AI-assisted builds (36%) are sites where AI coding tools were used during development but a traditional stack was deployed.
The remaining 58% of human/CMS sites are primarily WordPress, Shopify, and other traditional CMSes where no strong AI signals were detected. Note that some of these sites may still use AI for content generation — our detection focuses on the build stack, not content.

Most Detected Builders — Full Ranking
All builder and CMS technologies detected this month, ranked by number of websites. Each links to its builder detection page.
Frequently Asked Questions
What counts as an "AI-built" website?
An AI-built website is one deployed via an AI website builder platform — tools like Framer, Webflow, Lovable, Durable, or 10Web. These platforms use AI to generate the site layout, design, copy, and sometimes code. Detection is based on fingerprints in the site's HTML, scripts, DNS records, and HTTP headers.
How is AI-assisted development different from AI-built?
AI-assisted development refers to sites where a traditional tech stack (React, Next.js, Vue, etc.) was deployed, but signals suggest AI coding tools were used during development. These sites weren't created by an AI builder, but AI played a significant role in writing the code. The stack is conventional; the workflow was AI-augmented. Learn more on the AI detection explainer.
How accurate are these classifications?
Classifications are based on a combination of fingerprint matching, confidence scoring, and signal weighting. Accuracy is high for AI-native builder platforms (>95%), where the platform leaves distinctive code signatures. AI-assisted detection is inherently less precise since AI coding tools leave fewer traces. See the methodology page for full details.
Are these the same websites scanned every month?
No. The dataset reflects websites actually scanned by users of AI Website Detector during May 2026. Each month brings a different set of scanned domains. Sites scanned in multiple months may appear in multiple reports. The data is organic — driven by what our users are researching via the tech stack detector.
Can I use this data in a report or article?
Yes. This data is freely available. Attribution to AI Website Detector is appreciated but not required. For bulk data or API access, see our developer docs.
