Is This Website Built With Stripe?

How to Tell if a Website Uses Stripe

Identifying whether a website was built with Stripe 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 1 Stripe-specific signals, and returns a verdict with a confidence score.

You might want to detect Stripe 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 Stripe?

Stripe is a developer-focused online payment processing platform used by e-commerce businesses, SaaS companies, and independent developers to handle transactions, subscriptions, and financial infrastructure. The AIWebsiteDetector.com engine identifies Stripe-powered sites primarily through one script pattern, typically the presence of Stripe's JavaScript library loaded from its dedicated CDN domain, most commonly `js.stripe.com`, which is injected into pages where payment forms or checkout flows are initialized. This script tag is a highly reliable signal because Stripe's client-side SDK must be loaded directly from its own origin for security and PCI compliance reasons, meaning sites cannot self-host or proxy it without breaking functionality. Because of this architectural constraint, detection confidence is consistently high — the presence of the `js.stripe.com` script is effectively a definitive indicator that a site has integrated Stripe's payment stack. Stripe itself is a cloud-hosted, infrastructure-as-a-service platform with no self-hosted option, making every detected instance a live integration with Stripe's managed payment systems rather than a locally deployed clone.

It is primarily used for business websites, portfolios, landing pages, and personal sites without coding knowledge.

How to Manually Detect Stripe Websites

Method 1 — View Page Source

Open the website in your browser
Press Ctrl+U (Windows) or Cmd+Option+U (Mac)
Search (Ctrl+F) for stripe or stripe
If found in script src, class names, or meta tags — it's likely Stripe

Method 2 — Browser DevTools Network Tab

Press F12 to open DevTools
Click the Network tab and reload the page
Filter by stripe in the search box
If you see requests to Stripe-specific domains, it's confirmed

Faster: Skip the manual steps — paste the URL into our scanner above and we check all 1 signals in seconds.

How Our Stripe 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 1 Stripe-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

Frequently Asked Questions

How can I tell if a website was built with Stripe?

The most reliable ways to detect Stripe are: (1) open DevTools → Network tab and look for requests to Stripe-specific CDN domains, (2) view page source and search for Stripe-specific class names or data attributes, (3) use our free scanner — we check 1 detection signals automatically and return a confidence score.

Is your Stripe detector free?

Yes, completely free. Paste any URL into our scanner and we'll analyze it for Stripe fingerprints immediately. No account required, no limits on scans.

How accurate is the Stripe detection?

We check 1 unique Stripe 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 Stripe 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.
