Is This Website Built With Cursor?

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

How to Tell if a Website Uses Cursor

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

You might want to detect Cursor 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 Cursor?

Cursor is an AI code editor that helps developers write code faster. Sites built using Cursor may include built-with-cursor or cursor-ai markers when developers add attribution.

It is primarily used for powering websites built by developers using AI coding assistants or modern JavaScript frameworks.

Signs a Website Is Built With Cursor

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

Medium Confidence

HTML Attributes & Class Names

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

Medium Confidence

Meta Tags

Some Cursor sites include a generator meta tag or other platform-specific meta elements in the document head.

How to Manually Detect Cursor 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 cursor or cursor
  4. If found in script src, class names, or meta tags — it's likely Cursor

Method 2 — Browser DevTools Network Tab

  1. Press F12 to open DevTools
  2. Click the Network tab and reload the page
  3. Filter by cursor in the search box
  4. If you see requests to Cursor-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 Cursor 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 Cursor-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 Cursor?

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

Is your Cursor detector free?

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

How accurate is the Cursor detection?

We check 3 unique Cursor 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 Cursor 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.
