Identifying whether a website was built with Thunkable used to require technical expertise — inspecting source code, tracing network requests in DevTools, and knowing which patterns to look for. Our free scanner automates all of that: it fetches the page, analyzes 8 Thunkable-specific signals, and returns a verdict with a confidence score.
You might want to detect Thunkable for competitive research, due diligence before acquiring a site, or simple curiosity. Whatever the reason, this page covers every method — automated and manual.
Thunkable is a no-code and AI-assisted platform designed primarily for mobile app development, enabling entrepreneurs, educators, and non-technical creators to build cross-platform iOS and Android applications through a drag-and-drop interface. The AIWebsiteDetector engine identifies Thunkable-built projects and published app landing pages using a combination of 3 distinct script patterns, 2 CDN domains, and 2 HTML patterns, along with 1 meta tag pattern that appears consistently across sites generated or hosted through the platform. These signals — including characteristic script src attributes and CDN domain references embedded in the page markup — allow the detector to distinguish Thunkable deployments from generic hosted sites with high confidence. Thunkable occupies a notable space in the app-builder ecosystem by supporting both web-published project pages and live mobile app previews, which means its detection fingerprint spans multiple deployment contexts rather than a single site type. The platform operates on a freemium model with paid tiers unlocking advanced features, and its hosted projects typically resolve through Thunkable-controlled infrastructure, reinforcing the reliability of CDN-based signals as a detection anchor.
It is primarily used for web applications, internal tools, customer portals, and SaaS products — without writing code.
Visit Thunkable official websiteOur detection engine checks 8 unique Thunkable fingerprints. Here are the most reliable signals:
Assets (images, scripts, fonts) are loaded from Thunkable-specific CDN domains. This is one of the most reliable signals because CDN domains are hard to hide.
thunkable.comthunkable.ioThunkable loads specific JavaScript runtime files or loads scripts from identifiable URLs. Checking script src attributes reveals the platform.
thunkable.comthunkable.iothunkable.coThunkable injects proprietary class names, data attributes, or markup patterns into the page HTML that are unique to the platform.
thunkabledata-thunkableSome Thunkable sites include a generator meta tag or other platform-specific meta elements in the document head.

Script analysis
We scan all loaded JavaScript files for known CDN paths and runtime names
CDN domain matching
We cross-reference every asset request against known platform CDNs
HTML pattern scanning
We search the DOM for platform-specific class names and data attributes
Header inspection
We read HTTP response headers that identify the server or platform
Meta tag extraction
We check generator and other meta tags in the document head
Confidence scoring
We weight each matched signal and normalize to a 0–99% score

Get started with ThunkableThe most reliable ways to detect Thunkable are: (1) open DevTools → Network tab and look for requests to Thunkable-specific CDN domains, (2) view page source and search for Thunkable-specific class names or data attributes, (3) use our free scanner — we check 8 detection signals automatically and return a confidence score.
Yes, completely free. Paste any URL into our scanner and we'll analyze it for Thunkable fingerprints immediately. No account required, no limits on scans.
We check 8 unique Thunkable fingerprint signals across HTML, JavaScript, CDN domains, meta tags, and HTTP headers. Our confidence score reflects how many signals matched — a score above 70% is a strong indicator. We cap accuracy at 99% to reflect that all fingerprint-based detection is probabilistic.
Yes. Custom domains don't hide the underlying platform. The JavaScript files, CDN requests, HTML attributes, and server headers all remain identifiable regardless of the domain name used. Our scanner fetches the page directly and analyzes its technical composition.
