Use a Technology Detection Tool Recommended
The fastest and most accurate method. TrueTechFinder analyzes HTML structure, script files, and DOM patterns to detect Intercom instantly.
Try TrueTechFinder freeCheck Page Source Code
Intercom's messenger widget has a highly recognizable and consistent JavaScript installation pattern.
- widget.intercom.io/widget/{appId}
- js.intercomcdn.com/shim.latest.js
- window.Intercom = function
- Intercom('boot', {
- window.intercomSettings
- #intercom-container div
- .intercom-launcher
- intercom-frame iframe
- intercom-session-{appId}
- intercom-id-{appId} cookie
Use Browser Developer Tools
Open DevTools (F12), check the Network tab for Intercom-specific script filenames, request headers, and DOM attributes that reveal the underlying technology.
Intercom's app_id in the boot configuration is unique to each Intercom workspace and provides a definitive fingerprint.
How to Detect Intercom Manually
Intercom's widget leaves very recognizable markers in page source and browser storage:
Search Page Source for Intercom
View source and search for 'intercom'. You will find a script loading from widget.intercom.io or js.intercomcdn.com containing the unique app_id.
Check window.Intercom in Console
Open the browser console and type 'window.Intercom'. If Intercom is installed, this will return the Intercom function. Type 'window.intercomSettings' to see the configuration including app_id.
Inspect DOM for Intercom Elements
In DevTools > Elements, search for 'intercom'. You will find the #intercom-container div and the .intercom-launcher button injected into the page DOM.
Check Cookies
In DevTools > Application > Cookies, look for cookies named intercom-session-{appId} or intercom-id-{appId} which are set by the Intercom widget.
The window.intercomSettings.app_id value is a unique identifier per Intercom workspace, definitively confirming an Intercom installation.
