Quick Facts
Quick Answer
Microsoft Clarity is a free behavior analytics platform offering session recordings, heatmaps, rage-click detection, and scroll tracking. It is widely adopted by SaaS companies, ecommerce sites, and marketing teams as a zero-cost alternative to Hotjar.
🧠What is Microsoft Clarity?
Microsoft Clarity is a free user behavior analytics tool built by Microsoft. Launched in 2020, it allows website owners to visualize how users interact with their pages through heatmaps, session recordings, and behavioral metrics.
Unlike traditional analytics tools that focus on traffic numbers, Clarity focuses on the quality of user experience — revealing where users click, how far they scroll, and where they get frustrated (rage clicks, dead clicks).
- •Session Recordings: Watch real user sessions to understand navigation paths
- •Heatmaps: See aggregated click, scroll, and move patterns across pages
- •Rage Click Detection: Identify frustrating UI elements users repeatedly click
- •Scroll Depth Tracking: Understand how far users read page content
- •AI Insights: Automated summaries of user behavior trends
🔍How to Detect Microsoft Clarity on a Website
There are several ways to identify whether a website is using Microsoft Clarity.
Use a Technology Detection Tool Recommended
The fastest and most accurate method. TrueTechFinder analyzes HTML structure, script files, and DOM patterns to detect Microsoft Clarity instantly.
Try TrueTechFinder freeCheck Page Source Code
TrueTechFinder identifies Microsoft Clarity installations using a multi-layer signal approach across scripts, network requests, and DOM markers.
- clarity.ms/tag/
- https://www.clarity.ms/s/
- clarity.ms/collect
- window.clarity
- window.claritySettings
- clarity('set', ...)
- www.clarity.ms/collect
- clarity.ms/tag/{projectId}
- _clck cookie
- _clsk cookie
- _clst cookie
Use Browser Developer Tools
Open DevTools (F12), check the Network tab for Microsoft Clarity-specific script filenames, request headers, and DOM attributes that reveal the underlying technology.
Clarity detection is highly reliable due to consistent script URL patterns that cannot be proxied without custom configuration.
How to Detect Microsoft Clarity Manually
You can identify Clarity on any website using these methods without a tool:
View Page Source (Ctrl+U)
Search for 'clarity.ms' in the page source. A Clarity installation will include a script tag pointing to clarity.ms/tag/ followed by a unique project ID.
Check the Network Tab in DevTools
Open DevTools > Network, reload the page, and filter by 'clarity.ms'. You will see collect requests sent to Microsoft's Clarity servers.
Check JavaScript Console
Type 'window.clarity' in the browser console. If Clarity is installed, this object will be defined and will not return undefined.
Inspect Cookies
In DevTools > Application > Cookies, look for _clck, _clsk, or _clst cookies which are set by Microsoft Clarity.
The clarity.ms/tag/{ID} script pattern is unique to Clarity and cannot be confused with other tools.
