Server-side Tracking. Without the BS.
Privacy-first tracking that works — even when everything else is blocked.
Signals runs independently from Google or Tag Managers. It captures events before any JavaScript is loaded, directly at the edge.
Why Signals?
Privacy-first tracking that actually works
100% Cookie-free
No cookies, no persistent identifiers, no user fingerprinting. Fully GDPR-compliant by design.
Edge-ready
Runs on Cloudflare Workers, AWS Lambda@Edge, and other edge runtimes for ultra-low latency.
Consent-aware
Built-in consent logic ensures only qualified sessions are forwarded to analytics tools.
How it works
Three-Layer Tracking Model
Layer 1: Edge Request
before page render
Captures headers, IP (anonymized), user agent, URL, UTM params. Builds the foundation for context-based session grouping.
- Anonymous IP hashing
- UTM parameter capture
- User agent analysis
- Session context building
Layer 2: Edge Response
before browser sees content
Detects errors, redirects, page views. Fully invisible to blockers — works even if user rejects cookies.
- Error detection
- Redirect tracking
- Page view capture
- AdBlock resistance
Layer 3: Client
optional
Only runs if allowed by consent. Adds marketing events like view_cart, view_promotion, checkout_step.
- Consent-gated execution
- E-commerce events
- Custom event tracking
- CMP integration
