Yes Gathering and displaying client-side browser fingerprinting metrics (User-Agent, WebGL hash, Canvas, audio latency) is entirely composed of standard web APIs and frontend dashboards.

Competitors mentioned: EFF Cover Your Tracks, Cloudflare reputation scoring
Concerns raised: Uniqueness scores implausibly high (1 in billions) compared to actual Earth population, Inconsistent results across browsers and sessions undermine reliability, AI-generated explanations are unclear and unhelpful, Doesn't clarify which specific attributes are actually uniquely identifying, Uniqueness alone doesn't indicate tracking ability or malicious intent
Feature requests: Clarify which specific browser/hardware attributes contribute to uniqueness, Explain difference between consistent vs randomized fingerprint changes, Improve clarity of technical explanations beyond AI slop

Same idea, different domain
Nobody's really built a observability & eval tool for Media & entertainment yet.
