Know every script running on your client websites.
Modern websites load dozens of third-party scripts, analytics, ads, chatbots, session recording, retargeting. When one gets added, removed, or modified without your knowledge, it can break tracking, slow the site, or create compliance issues.
Why third-party scripts are a risk
Every external script on a website is a dependency you do not control.
Scripts load without your knowledge
Client teams, CMS plugins, and theme updates can add scripts you never approved. Some inject tracking, some inject ads, some inject vulnerabilities.
Removed scripts break functionality
A developer removes a tracking pixel during a cleanup. Campaign attribution stops. You find out when the client asks why conversions dropped.
Script changes affect performance
Third-party scripts can slow page load, block rendering, or conflict with other tools. A new heavy script can tank Core Web Vitals overnight.
Unauthorized data collection
New scripts may collect user data without proper consent. If your agency set up the site, you could be held responsible for undisclosed data practices.

How Tracefox monitors third-party scripts
Full browser scan
Tracefox visits your website with a real headless browser. It loads the page, executes JavaScript, waits for dynamic scripts, and captures every script that runs, including ones loaded after the initial page load.
Script inventory
Each scan creates a complete inventory of every external script URL, inline script hash, third-party domain, and network request. This becomes the baseline for comparison.
Change comparison
On every subsequent scan, Tracefox compares the current state against the previous scan. New scripts, removed scripts, and modified scripts are identified and categorized.
Risk classification
Each detected change is assigned a severity level (HIGH, MEDIUM, LOW) based on what changed and whether a consent banner is present. Known trackers without consent are flagged as high risk.
Instant alerts
You receive email and Slack alerts for high-risk changes. Weekly digest summaries cover all activity across all monitored sites.
