PUBLIC RESOURCE DIRECTORY

Trial abuse checkers and supporting demos

Four public resources introduce device, visit, network and browser evidence. Use their defined scope when planning an account-linked trial evaluation.

By Ethan Cole · Updated October 23, 2026

START WITH THE VISIT

Inspect the evidence
before granting access.

ShieldLabs provides current identification and risk context. The complete trial workflow connects the supported result to an account, the requested benefit and prior grants.

RESOURCE ≠ ENTITLEMENT RECORD

A public result describes its own test. It does not know which introductory benefit your application has already granted.

Links open provider sites. This directory does not embed their tests or receive the results.

01 / ShieldLabs

ShieldLabs Anonymity Checker

Visit and risk context

Inspect current visitor/device, network and risk evidence before designing the trial integration.

Output
Identifiers, named network conditions and risk output within the public checker’s scope.
Access
Public checker. Integrated account association and trial eligibility require the supported product setup.
Evaluation idea
Use a known legitimate visit as the baseline. In an integrated pilot, associate the finding with a permitted trial activation and its prior entitlement.

02 / Fingerprint

Fingerprint identification playground

Hosted recognition and signals

Explore returning-browser recognition and the signals exposed for a current event.

Output
Visitor/event identity and available Smart Signals.
Access
Public playground; production field access and client support depend on the selected plan.
Evaluation idea
Compare a known repeat visit with distinct-device controls. Keep the provider identifier separate from a person and from an application trial grant.

03 / IPQualityScore

IPQualityScore proxy and VPN lookup

Connection context

Understand the IP-level evidence that can corroborate a signup assessment.

Output
IP/network classifications and supported risk fields when the lookup completes.
Access
Public lookup route; verification and access restrictions can apply. Device API entitlement is separate.
Evaluation idea
Use only an owned or permitted test address. Shared-network conditions and an incomplete lookup should retain their actual meaning.

04 / BrowserLeaks

BrowserLeaks JavaScript information

Raw browser observations

Inspect the browser environment that contributes observations in a permitted evaluation.

Output
Navigator, screen, language, timezone and related attributes.
Access
Public diagnostic; it does not decide trial eligibility or return a complete account-abuse finding.
Evaluation idea
Inspect one supported change at a time and include genuine configurations. Raw attributes are evidence for interpretation, not an identity proof.

Keep the result in scope.

A risk score, identification confidence, IP classification and raw browser attribute describe different things. Retain the source, time and supported meaning.

A missing result remains unavailable. It is not a clean signup or proof of another eligible participant.

Then evaluate the activation.

  1. Use an independently eligible case and an authorized repeat request.
  2. Locate the account, event and prior grant.
  3. Inspect the trusted result and actual user outcome.
  4. Add legitimate shared-resource cases.

Account-based and assisted evaluations

Castle, SEON, Verisoul, Stytch, Trueguard, Abstract API and DataCops provide product-specific setup or account access. API documentation, a trial account and a sales walkthrough are distinct from the four public resources listed above.

FAQ

Does this directory run checks on visitors?

No. It lists external resources and filters their static cards. Tests open on provider sites; the directory does not embed those tests or receive their output.

Can a public checker decide whether someone already used our trial?

It exposes only its defined evidence. Your complete evaluation needs the supported account association, entitlement scope, prior grants and protected activation event.

Do IP lookups establish device or person identity?

No. A lookup describes network conditions under its supported contract. Device relationships, authenticated accounts and a physical person are separate concepts.

How should an incomplete public result be interpreted?

Keep it unavailable. An access restriction, timeout or missing assessment is not a low-risk finding or proof of a new eligible participant.
