What Fingerprint Measures
14 component families across navigator, screen, WebGL, canvas, audio, fonts, storage, permissions, privacy resistance, and JA4-style summaries.
Fingerprint Detection Platform
See your browser the way the network sees it.
Analyze browser, bot, headless, privacy-resistance, and JA4-style signals with public-safe redaction, real algorithms, trace-linked evidence, and integrations across Atlas, Monitor, Trace, BrowserOps, Sandbox, Evals, and MCP.

Privacy and Redaction
Collection starts from visible user action. Public output uses hashes, truncation, aggregate counts, and explicit degraded states.
Headless and Automation Signals
Deterministic browser checks explain webdriver, automation globals, user-agent hints, plugin inconsistencies, and rendering anomalies.
Compare Fingerprints
Weighted exact and fuzzy comparison shows matching components, changed signals, likelihood scores, confidence, and caveats.
JA4 / JA4M Research
Vercel JA4 digest metadata is never public in raw form. JA4M client metadata is labeled research, not certainty.
API / MCP / CLI
OpenAPI, MCP tools, llms files, policy routes, and platphormctl examples expose public-safe fingerprint intelligence.
Your Browser Fingerprint
Real-time analysis of your device signature
This workbench runs locally first. It generates deterministic hashes and confidence scores from real browser components, and it does not submit anything until you choose a redacted submission action.

No browser signals collected yet
Use Inspect Browser to run a visible, local-only collection. The dashboard does not silently submit fingerprints.

Educational Use and Limits
Fingerprint explains exposed signals for debugging, education, security research, and platform trust work. It does not claim identity certainty, does not perform covert tracking, and keeps protected operations behind PLATPHORM_API_KEY.
