About

Strata — The Developer's DataLayer Inspector

Stop guessing if your GTM dataLayer is working correctly. Strata gives you real-time visibility into every dataLayer.push() call, with powerful validation and export tools built for developers and technical analysts.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🔍 REAL-TIME EVENT CAPTURE

• Intercepts all dataLayer.push() calls as they happen 
• Color-coded event categories (GTM, Ecommerce, Custom, Errors) 
• Multi-container GTM support 
• Pause and resume recording anytime 
• Search and filter through captured events

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

✅ SCHEMA VALIDATION

Define expected event structures and validate automatically:

• Type placeholders: @string, @number, @boolean, @array, @object • Optional fields: @string? won't fail if missing • Enum validation: @enum(USD, EUR, GBP) • Auto-generate schemas from captured events • Import/export schemas as JSON files

Perfect for catching tracking issues before they reach production.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

📤 EXPORT OPTIONS

• JSON: Export events for debugging or documentation 
• Test Assertions: Generate Playwright or Cypress test code 
• Evidence: Create PNG or PDF screenshots for QA reports

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

⌨️ DEVELOPER EXPERIENCE

• Keyboard shortcuts (Alt+Shift+D to toggle) • JSON tree view with syntax highlighting • Copy events to clipboard • Quick popup view from toolbar

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🔒 PRIVACY FIRST

Strata operates entirely locally. No data is collected, transmitted, or stored externally. Your dataLayer events never leave your browser.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
