The clearest finding

Fingerprint: The same visitor ID was returned across both isolated sessions. Thumbmark: Different identifiers across isolated sessions; stable on repeat visits. Session isolation alone does not guarantee that a service cannot link sessions.

Every family. Visible coverage.

Observed results are specific to the recorded build, settings, and test. A fingerprint or a bot classification is an observation, not a universal pass or fail.

CreepJS-derivedLimited evaluation

Reference CreepJS test: headless 0%, stealth 0%, like-headless 25%.

Original CreepJS reference test
  • Headless: [0, 0, 0]%; stealth: [0, 0, 0]%; like-headless: [25, 25, 25]% (A, A repeat, B).
  • FP ID stable on repeat: true. Equal across independent sessions: true.
  • The reference project is not every CreepJS-derived script cataloged by fingerprint.garden. These heuristic percentages are not probabilities of detection.
  • Debug notifications were suppressed during collection, as in normal REL Debug verification.

Fingerprint BotDLimited evaluation

BotD 2.0.0 returned bot: false in both independent sessions.

Published BotD SDK, local fixture
  • Bot: [false, false] (A, B). No repeat-visit identity test; BotD returns a bot classification.
  • The official linked demo returned HTTP 404. Evaluated the unmodified npm SDK in a locally served test page instead.
  • SDK monitoring was disabled. This is a client-library result, not Fingerprint Pro Bot Detection.

FingerprintJS / FingerprintMeasured

The same visitor ID was returned across both isolated sessions.

Fingerprint Pro public demo
  • Bot: not_detected, not_detected, not_detected (A, A repeat, B).
  • Browser tampering: [false, false, false]; suspect score: [11, 11, 11]; virtual machine: [true, true, true] (A, A repeat, B).
  • Visitor ID stable on repeat: true. Equal across independent sessions: true.
  • Vendor demo on one shared direct connection. Not an evaluation of the open-source FingerprintJS library or every customer integration.

ThumbmarkJSMeasured

Different identifiers across isolated sessions; stable on repeat visits.

Thumbmark public demo
  • Bot: [false, false, false]; danger level: [0, 0, 0] (A, A repeat, B).
  • Visitor ID stable on repeat: true. Equal across independent sessions: false.
  • Thumbmark stable on repeat: true. Equal across independent sessions: false.
  • The vendor-hosted demo includes server-side signals. Different identifiers in this small run do not establish long-term unlinkability.

Scope and method

Live browser runs

Each recorded test runs in the actual REL Debug browser through its supported local API. Two independent sessions created from the same Private identity profile are compared, including repeat visits where a test exposes an identifier. Both use the same direct connection with ad blocking disabled.

The downloadable report records the exact build, engine version, collection time, test URL, and observed values. Public results omit raw visitor identifiers and network addresses.

What the catalog tells us

fingerprint.garden catalogs observed fingerprinting scripts and canvas artifacts. Its family counts are artifact counts, not REL scores, test counts, or market share. This page uses its pinned catalog snapshot, generated October 28, 2026.

“Multiple vendors” and “Unattributed vendor” are catalog categories. A reference-library test does not cover every script derived from that library.

What remains unmeasured

“Not evaluated” means there is no recorded live result for that family. Some services expose their decisions only through a customer integration or server API. Loading a protected website alone does not reveal that decision.

These runs do not establish population uniqueness, long-term unlinkability, proxy performance, CAPTCHA success, or results for other vendor deployments. Different isolated sessions can still be correlated through shared network and device signals.
