A summary, not legal advice.

WHY IT MATTERS

A browser controls its own JavaScript, but not the network it connects over. liarjs exploits that gap: it reads the fingerprint inside the browser, reads the TLS, HTTP and ASN view from the edge that served the request, and flags every place the two stories disagree.

BUILD FROM THIS

  • TypeScript under MIT, split into three parts: a CLI and driver, 19 browser-side fingerprint probes, and 40 consistency rules as pure functions. liarjs.dev runs exactly these checks.

WHO IT'S FOR

People checking whether their privacy settings actually hold, and developers working on bot detection or traffic analysis.

START IN 5 MINUTES

# Open liarjs.dev and it scans your browser right away — no install, no signup.

CAVEATS

  • A diagnostic tool: the result tells you where two views disagree, not who someone is or whether they are safe.
