Fake-account checkers, demos and evaluations

Use a public demo to inspect output and an assisted pilot to test deployment. Check the type of evaluation route, required access and output available for each product.

PUBLIC TESTS AND EVALUATION RESOURCES

Evaluate the registration event.

Compare permitted repeat signups and legitimate new customers. Record the account association, device/network findings, timestamp and missing fields. Follow the event through server verification and customer recovery.

Links open the provider or project’s own site. This directory does not embed their checkers or receive their results. A browser observation, an IP classification and an account-based evaluation answer different questions.

Find the right test

Choose a resource by the evidence it exposes. Product evaluations for the full shortlist remain below.

4 of 4 resources

01 / ShieldLabs

ShieldLabs Anonymity Checker

Visitor, device and risk context

Explore current device/network evidence and identification within the public checker’s scope.

Output
Identifiers, named network conditions and risk output available to the public visit.
Access and limits
Public checker; account events and production integration require supported account association.
Evaluation idea
Record a permitted baseline visit and the individual findings. Keep an unavailable assessment distinct from a low-risk result.

02 / Fingerprint

Fingerprint identification playground

Hosted recognition and Smart Signals

Inspect a current identification event and the exposed browser and network signals.

Output
Event/visitor identity and available Smart Signals; fields depend on the demo and product plan.
Access and limits
Public playground; production signal and client entitlements are separate.
Evaluation idea
Read tampering, automation and network outputs separately from the visitor identifier and any aggregate score.

03 / BrowserLeaks

BrowserLeaks JavaScript information

Individual browser surfaces

Inspect JavaScript-visible attributes and supported browser capabilities.

Output
Navigator, screen, locale, timezone and related technical values.
Access and limits
Public diagnostic page. Other BrowserLeaks pages cover separate surfaces such as WebRTC.
Evaluation idea
Inspect one permitted configuration and retain missing fields as unavailable. Explain causes instead of declaring every unusual value fraudulent.

04 / IPQualityScore

IPQualityScore proxy and VPN lookup

IP and connection context

Inspect network context that can corroborate a browser investigation.

Output
Supported IP classifications and risk fields when the lookup completes.
Access and limits
Public lookup route; verification or access restrictions may apply. Device-product entitlement is separate.
Evaluation idea
Use an owned or permitted address. Keep network reputation, browser integrity and account eligibility distinct.

Keep the comparison repeatable

  1. Define the protected action and use only your own or authorized data.
  2. Record the provider, timestamp, assessed entity, field definitions and scale.
  3. Change one permitted condition and repeat the same action.
  4. Include legitimate controls and keep unavailable fields distinct from negative findings.
  5. Evaluate the supported integration and account access before applying the result to customers.

Product access and full-shortlist evaluations

These are the existing vendor routes and their recorded access conditions. A trial request, product walkthrough or documentation page is not another public checker.

What a demo can establish

A public browser demo can show the output for your current visit. It cannot establish how a detector performs on your customers, direct API clients or a managed production rollout. Evaluate permitted repeat-account scenarios and known legitimate shared users on the same routes.

Evaluation routes for the ten products; checked October 21, 2026.
ToolEvaluation typeWhat to test
ShieldLabsPublic identification and risk demoInspect your own browser visit and the available identification and risk context. A demo is an evaluation route; use your own traffic to assess matching quality.
SEONTrial request and plan comparisonTrial and commercial access are requested through the vendor; this route is not a public live browser checker.
SiftIntegration guide and assisted accessInspect the device/session workflow in public docs, then confirm account entitlement and a pilot with Sift.
FingerprintPublic repeat-signup scenarioAn interactive example shows repeated trial registrations from the same browser/device. Use fictitious test inputs if trying it; the example is not a production accuracy benchmark.
VerisoulAssisted product evaluationRequest an evaluation with the vendor; no public unrestricted browser checker or current universal trial duration is established here.
CastleSelf-serve evaluation accountThe Free plan is an account-based evaluation route with published limits, not an anonymous browser checker.
DataDomeSales-assisted Account Protect evaluationRequest an evaluation of the registration integration and account insights. Confirm that Account Protect is enabled; a Bot Protect demonstration alone does not establish this feature scope.
Arkose LabsSales-assisted demoUse Book a Demo on the product page; assess risk detection and challenge behavior on the intended user flows.
IPQualityScoreDevice API documentation and account accessReview the documented device response and obtain access to that product; confirm entitlement before testing. The route is not an anonymous live device checker.
SardineSales-assisted onboarding and device demoRequest an evaluation focused on fake-account creation, account relationships and the relevant web or mobile surface. The sales form is not a public live checker.

Keep the evaluation comparable

  1. Choose the protected route and business outcome.
  2. Check the required feature and product tier.
  3. Test known repeat accounts, storage resets, shared households and separate legitimate users.
  4. Inspect backend verification and investigation data.
  5. Compare matching outcomes, latency and billable events.

See the deployment guide and full scoring rubric.

FAQ

Can one device or IP flag establish that an account is fake?

No. A shared network or unusual device property is not proof of a fake identity. Evaluate the actual signup event, supported signals and relevant account history with controls for genuine customers.

Does this directory collect my checker result?

No. The cards and links are static HTML, and JavaScript only filters this directory. Each linked provider controls collection, results, retention and access on its own site.

Are public demos, sandboxes and product trials equivalent?

No. A public demo exposes a limited interaction. A sandbox exercises documented test behavior, while an account-based or assisted trial evaluates a particular product scope. Keep each output and its access conditions attached.

Can scores from different checkers be compared directly?

Only when their assessed entity, definitions and scales are comparable. Record the individual fields and missing results. A network reputation score, identification confidence and account-risk verdict are different measures.
