How to Tell if a Website Uses Gamma
Identifying whether a website was built with Gamma 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 13 Gamma-specific signals, and returns a verdict with a confidence score.
You might want to detect Gamma for competitive research, due diligence before acquiring a site, or simple curiosity. Whatever the reason, this page covers every method — automated and manual.
What is Gamma?
Gamma is an AI-powered presentation, document, and webpage creator that generates structured, visually designed content from a prompt — blending the functionality of Google Slides, Notion, and a website builder in a single tool. Unlike traditional slide builders, Gamma produces web-native content that works responsively across devices without the constraints of fixed slide dimensions. It's used by teams for internal presentations, product showcases, client proposals, and public-facing landing pages that need to be built quickly. Gamma-published pages load all assets from gamma.app domains, use gamma-specific layout and styling attributes in their markup, and follow Gamma's distinctive nested card layout structure. The Gamma AI integration is visible in the predictable section structure of generated content. Free plans include unlimited AI generations, with Pro plans at $10/month.
It is primarily used for marketing sites, landing pages, portfolios, and business websites — all generated from prompts or visual editors with AI assistance.

Our detection engine checks 13 unique Gamma fingerprints. Here are the most reliable signals:
CDN Domain
Assets (images, scripts, fonts) are loaded from Gamma-specific CDN domains. This is one of the most reliable signals because CDN domains are hard to hide.
assets.gamma.appgamma.appgamma.siteJavaScript / Script Files
Gamma loads specific JavaScript runtime files or loads scripts from identifiable URLs. Checking script src attributes reveals the platform.
gamma.appcdn.gamma.appgamma.siteHTTP Response Headers
Gamma-hosted sites respond with specific HTTP headers that identify the platform or infrastructure. These are visible in DevTools → Network tab.
serverx-powered-byHTML Attributes & Class Names
Gamma injects proprietary class names, data attributes, or markup patterns into the page HTML that are unique to the platform.
gamma-data-gammagamma.appMeta Tags
Some Gamma sites include a generator meta tag or other platform-specific meta elements in the document head.

Method 1 — View Page Source
- Open the website in your browser
- Press
Ctrl+U(Windows) orCmd+Option+U(Mac) - Search (
Ctrl+F) forgammaorgamma - If found in script src, class names, or meta tags — it's likely Gamma
Method 2 — Browser DevTools Network Tab
- Press
F12to open DevTools - Click the Network tab and reload the page
- Filter by
gammain the search box - If you see requests to Gamma-specific domains, it's confirmed
How Our Gamma Detector Works
When you submit a URL, our engine fetches the page from its server — just like a browser would — then analyzes the response across 13 Gamma-specific fingerprints:
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 GammaFrequently Asked Questions
How can I tell if a website was built with Gamma?
The most reliable ways to detect Gamma are: (1) open DevTools → Network tab and look for requests to Gamma-specific CDN domains, (2) view page source and search for Gamma-specific class names or data attributes, (3) use our free scanner — we check 13 detection signals automatically and return a confidence score.
Is your Gamma detector free?
Yes, completely free. Paste any URL into our scanner and we'll analyze it for Gamma fingerprints immediately. No account required, no limits on scans.
How accurate is the Gamma detection?
We check 13 unique Gamma 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.
Can Gamma sites be detected if they use a custom domain?
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.
