AI Website Insights: September 2026
In September 2026, AI Website Detector scanned 3,893 unique websites and classified each one based on the technology stack, signals, and fingerprints detected in its code. Of those, 1,415 (36%) showed clear evidence of AI involvement — either through an AI website builder platform or AI-assisted development practices.
Compared to Aug 2026, total scan volume decreased by 7,145 websites. The share of AI-built sites decreased slightly by 2 percentage points, though the long-term trend remains upward.
Next.js remained the most commonly detected technology this month, appearing on 793 scanned websites — representing 28% of all builder detections.

Platform Analysis
Next.js led all detected technologies in September 2026 with 793 sites — a 28% 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 603 sites (21%). Both platforms represent traditional development approaches, suggesting AI adoption, while real, is still concentrated in specific segments.
Rounding out the top three, Elementor appeared on 274 sites, reinforcing the diversity of approaches being used to build production websites today.
AI Builder Spotlight
6 AI-native builder platforms appeared in this month's detections, collectively powering 267 websites (9% of all detected builder sites).
Lovable led the AI-native category with 126 sites. Framer followed with 72, and Webflow with 41. 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 dipped by 2 percentage points compared to Aug 2026. This may reflect a shift in the types of websites being scanned this month rather than a decline in AI adoption overall — the dataset is driven by user search behavior, which can vary by month.
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 36% AI involvement figure means that a significant and growing share of websites show detectable AI involvement. AI-native builds (5%) 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 (31%) are sites where AI coding tools were used during development but a traditional stack was deployed.
The remaining 64% 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.

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 September 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.
