Architecture & Overview
Tracium is a dual-plane telemetry platform designed to capture high-fidelity client telemetry alongside edge-intercepted automated traffic, AI scrapers, and headless HTTP clients.
The Client-Side Telemetry Blindspot
Standard web telemetry engines (Google Analytics 4, Plausible, Mixpanel) operate exclusively within the browser Document Object Model (DOM). This creates a structural telemetry blindspot:
Automated HTTP agents, raw LLM dataset scrapers (e.g., GPTBot, Bytespider), and headless curl sessions parse raw HTML without evaluating JavaScript runtimes.
Browser content-blocking extensions (uBlock Origin, Brave Shields, DNS-level Pi-hole filters) drop third-party analytics hosts before TCP handshakes initiate.
Dual-Plane Ingestion Topology
Tracium eliminates this telemetry blindspot by decoupling telemetry collection into two synchronized operational planes:
