DataLayer Guard by Code-Cube.io is a real-time dataLayer governance and monitoring tool. It provides automated quality assurance for your analytics by simulating full user visits and actions, such as clicks, "Add to Cart", or "Purchase", with a backend browser bot. The bot captures your frontend dataLayer activity and tracking behavior and validates it in real time against your rules, so your tags always receive complete and accurate data.
When data is missing or incorrect, you get a real-time alert before it affects your reports, your ad algorithms, or your business decisions.

Why dataLayer monitoring matters
The dataLayer is the foundation your tags build on. When an event is missing or a parameter has the wrong value or format, every tag that depends on it sends broken data, even when the tags themselves fire correctly. A broken dataLayer misleads your ad algorithms and your business decisions, and it is hard to spot without automated checks.
What DataLayer Guard does
Capability | What it does |
Page scenarios | Map your critical user journeys, such as logging in, handling the cookie banner, adding to cart, or checking out, and run them automatically |
Complete validation | Checks every event and parameter against your rules, from data availability to format, for example that price is sent as a number rather than a string |
Scenario Tester | Runs your scenarios live on-screen before you activate them, with a pass or fail status per step and the expected value next to the actual value |
Real-time alerts | Notifies you via email, Slack, Microsoft Teams, or WhatsApp as soon as live data breaks your rules |
Analytics vs. sales | Compares front-end analytics transactions with back-end sales to show where conversions are lost |
Living measurement plan | Automatically documents all dataLayer events and parameters as your implementation evolves |
No classic dataLayer? It's called DataLayer Guard because "dataLayer" is the best-known name for frontend JSON objects. If your site uses a different structure, DataLayer Guard adapts and observes any frontend object exactly as a real user would.
How it works
- Build: create page scenarios for your key user journeys, and reuse common steps with reusable components
- Test: run the scenarios in the Scenario Tester and fix any failing step before you go live
- Monitor: DataLayer Guard runs your scenarios automatically and validates the captured dataLayer activity against your rules
- Alert: when data is missing or incorrect, your team receives a real-time alert
Set up and use DataLayer Guard
These guides describe how to set up and use DataLayer Guard for your environment:
Monitoring via Page Scenarios
Reusable components
Scenario Tester
Network InspectorTip: The bot runs from dedicated IP addresses. To exclude these simulated visits from your analytics reports, email support@code-cube.io to request the IP addresses for filtering.
Frequently asked questions
Do I need a dataLayer to use DataLayer Guard?
No. DataLayer Guard can observe any frontend JSON object. For tracking that bypasses the page entirely, Network Inspector monitors the network requests themselves.
Will the simulated visits show up in my analytics?
They can. The bot runs from dedicated IP addresses, which you can filter out. Contact support@code-cube.io to request them.
How do I know my scenarios work before they go live?
Use the Scenario Tester. It runs your scenarios in a real browser while you watch, and shows exactly which step fails and why.
