LIVE BROWSER DIAGNOSTICS / 6 EXECUTION CONTEXTS
One browser.
Six perspectives.
Compare what the main Window sees with what Dedicated, Module, Shared and Service Workers actually report. Every missing response and inconsistent value is shown — never silently counted as a match.

01 — REACHABILITY
Execution contexts
Each worker is started independently on this secure origin.
02 — SIGNAL COMPARISON
Value-by-value inspection
Values are read from each realm separately and compared with the Window reference.
| Fingerprint signal | Window reference | Worker classic | Worker module | Shared classic | Shared module | ServiceWorker |
|---|---|---|---|---|---|---|

03 — EXCEPTIONS
Differences & errors
Unsupported fields aren't classified as matches; errors and timeouts are listed independently.
Run a comparison to inspect exceptions.
Local-first, transparent diagnostics.
The measurement runs in your browser. Fingerprint values are not uploaded to Social Browser or saved in an account. ServiceWorker is registered only within this diagnostic path and is unregistered after each test. This tool checks observable consistency, not security, authenticity or detection outcomes.
