Is This Website Built With Intercom?

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

How to Tell if a Website Uses Intercom

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

You might want to detect Intercom 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 Intercom?

Intercom is a customer messaging and engagement platform used primarily by SaaS companies, e-commerce brands, and B2B businesses to manage live chat, customer support, and targeted in-app communications. The platform is identifiable through a combination of technical signals, including 2 distinct script patterns — typically involving references to Intercom's CDN-hosted loader scripts and initialization code — alongside 1 HTML pattern that commonly manifests as a dedicated launcher element or iframe injected into the page DOM. Detection confidence is reinforced by the consistency of these signals across deployments, as Intercom's standardized embed snippet leaves recognizable fingerprints regardless of how the platform is configured by individual customers. The JavaScript initialization pattern typically includes a call to the `window.Intercom` function with an `app_id` parameter, making it one of the more reliably detectable third-party platforms in our engine. Intercom operates as a cloud-hosted SaaS product with tiered pricing plans, and because its client-side code is always served from Intercom's own infrastructure rather than self-hosted, the CDN script origins remain a stable and high-confidence detection vector.

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

Signs a Website Is Built With Intercom

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

High Confidence

JavaScript / Script Files

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

widget.intercom.iojs.intercomcdn.com
Medium Confidence

HTML Attributes & Class Names

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

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

Method 2 — Browser DevTools Network Tab

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

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

Is your Intercom detector free?

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

How accurate is the Intercom detection?

We check 3 unique Intercom 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 Intercom 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.
