Is This Website Built With Amplitude?

Paste any URL below. Our scanner checks 3 Amplitude-specific fingerprints — scripts, CDN domains, HTML attributes, and HTTP headers — and returns a confidence score instantly.

How to Tell if a Website Uses Amplitude

Identifying whether a website was built with Amplitude 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 3 Amplitude-specific signals, and returns a verdict with a confidence score.

You might want to detect Amplitude 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 Amplitude?

Amplitude is a product analytics platform used primarily by growth teams, product managers, and data analysts at software companies to track user behavior, measure feature adoption, and optimize digital experiences. When scanning for Amplitude implementations, AIWebsiteDetector.com's engine looks for two distinct script patterns — typically involving the loading of Amplitude's JavaScript SDK from endpoints associated with their delivery infrastructure — alongside one HTML pattern that reflects how the tracking snippet is embedded within a page's markup. These signals are highly reliable identifiers because Amplitude's initialization code follows a consistent structural signature, making it straightforward to distinguish from competing analytics platforms even when the snippet is minimally customized. The combination of script-based and HTML-based detection gives the engine strong confidence across a wide range of site types, from SaaS product dashboards to consumer mobile web applications. Amplitude operates as a cloud-hosted SaaS platform with tiered pricing that includes a free Starter plan, meaning its tracking code can appear on everything from early-stage startup sites to large enterprise products — a breadth of deployment that makes it one of the more frequently encountered product analytics tools in scan results.

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

Signs a Website Is Built With Amplitude

Our detection engine checks 3 unique Amplitude fingerprints. Here are the most reliable signals:

High Confidence

JavaScript / Script Files

Amplitude loads specific JavaScript runtime files or loads scripts from identifiable URLs. Checking script src attributes reveals the platform.

cdn.amplitude.comcdn2.amplitude.com
Medium Confidence

HTML Attributes & Class Names

Amplitude injects proprietary class names, data attributes, or markup patterns into the page HTML that are unique to the platform.

How to Manually Detect Amplitude Websites

Method 1 — View Page Source

  1. Open the website in your browser
  2. Press Ctrl+U (Windows) or Cmd+Option+U (Mac)
  3. Search (Ctrl+F) for amplitude or amplitude
  4. If found in script src, class names, or meta tags — it's likely Amplitude

Method 2 — Browser DevTools Network Tab

  1. Press F12 to open DevTools
  2. Click the Network tab and reload the page
  3. Filter by amplitude in the search box
  4. If you see requests to Amplitude-specific domains, it's confirmed
Faster: Skip the manual steps — paste the URL into our scanner above and we check all 3 signals in seconds.

How Our Amplitude 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 3 Amplitude-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 Amplitude?

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

Is your Amplitude detector free?

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

How accurate is the Amplitude detection?

We check 3 unique Amplitude 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 Amplitude 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.
