VPN Detection Review

VPN detection checkers and demos.

Open a vendor test, connect your VPN and compare the result. ShieldLabs and Fingerprint show browser/session workflows; IP lookups and dataset previews answer narrower questions.

PUBLIC TESTS AND EVALUATION RESOURCES

Which connection does the test see?

Record the public exit, network classifications and browser observations with the VPN disconnected, then connected through one permitted exit. IP, DNS and WebRTC checks cover different paths.

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.

7 of 7 resources

01 / ShieldLabs

ShieldLabs Anonymity Checker

Live browser/session test

Inspect your own visit, connection masking and device/network context.

Output: Risk score, identifiers and network signals when the check completes.
Access and limits: Public checker. A timed-out check has no verdict; use Check again to retry. Integrated evaluation uses Start Free.
Evaluation idea: Compare a regular browser visit with one permitted change, such as a private window or an authorized VPN connection.

02 / Fingerprint

Fingerprint VPN detection demo

Live browser/session demo

Inspect how the current browser event is assessed for VPN-related signals.

Output: Device/event context and VPN detection from the demo workflow.
Access and limits: Public demo; full Smart Signals and API access depend on the chosen plan or trial.
Evaluation idea: Use your own browser and compare the same test on your regular connection and an authorized VPN.

03 / ipgeolocation.io

ipgeolocation.io real-time detection

Live browser/network demo

Inspect the vendor’s separate client-side live detection workflow.

Output: VPN/proxy scores, confidence and IP/network observations exposed by the demo.
Access and limits: Public demonstration; integrated use needs a paid plan, with a trial request available.
Evaluation idea: Run the current-browser test and compare its scope with the documented IP Security response.

Open resource ↗Scope and scoring method →

04 / proxycheck.io

proxycheck.io single lookup

IP/network lookup

Inspect the current address through the single-IP web interface.

Output: Network/location information, classifications and available risk or confidence fields.
Access and limits: Public lookup with limits. API query allowances and plan conditions apply separately.
Evaluation idea: Use your own address or an address you are authorized to test, then record the timestamp and complete result.

05 / IPQualityScore

IPQualityScore proxy and VPN test

IP/network lookup

Inspect an IP-level proxy/VPN and fraud-risk lookup.

Output: IP lookup result when the provider allows the test to complete.
Access and limits: Public tool route; automated-browser access can be blocked. A blocked page is not a negative proxy result.
Evaluation idea: Open in a normal browser and use only your own or permitted test IP. Confirm the result before comparing scores.

06 / IPinfo

IPinfo current IP lookup

IP/network information

Read the network and location context for the current address.

Output: The address, ASN/network/location and any fields exposed by this public lookup.
Access and limits: Public page. Displayed web fields do not establish that every field is included in the free Lite API.
Evaluation idea: Record the network and date, then compare the documented Core or Max entitlement for your intended API call.

07 / proxycheck.io

proxycheck.io v3 test console

Response simulator, not a live detection test

Inspect dummy responses and status codes while building a v3 adapter.

Output: Simulated examples of the documented response and error contract.
Access and limits: Public documentation console. Its samples do not query the live API and consume no daily queries.
Evaluation idea: Exercise parsing and error handling. Keep these fixtures separate from the live single-IP lookup when evaluating detection.

Keep the comparison repeatable

Define the protected action and use only your own or authorized data.
Record the provider, timestamp, assessed entity, field definitions and scale.
Change one permitted condition and repeat the same action.
Include legitimate controls and keep unavailable fields distinct from negative findings.
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.

Try the tools

Public testing options.

ShieldLabs and Fingerprint offer browser demos; the other links let you inspect an IP or preview a dataset. Turn your VPN on and off to compare what each tool sees. Access conditions below were checked October 20, 2026.

Public testing options for all 10 vendors
Vendor	Test type	Open test	What to compare and access conditions
ShieldLabs	Browser and session demo	Run Anonymity Checker ↗	Open the checker with your VPN off and on; compare network signals, visitor/device identity and risk score. The separate VPN demo shows a regional-pricing flow.
IPQualityScore	Public IP checker	Open VPN detection test ↗	Submit your public exit IP and inspect the VPN/IP-risk result. Public lookups are limited; API access has separate account terms.
IPinfo	Public IP lookup	Check your IP and anonymization ↗	Compare the visible IP, ASN and anonymization fields before and after connecting. Provider details and some data require login or a plan.
MaxMind	Limited GeoIP preview	Open GeoIP demo ↗	Preview location and network data for up to 25 IPs. The public preview is a subset; full VPN and anonymizer fields may require access to the full dataset.
Fingerprint	Browser and checkout demo	Try VPN detection demo ↗	Activate regional pricing, connect a VPN with a different exit location, then repeat the action to compare the response.
proxycheck.io	Public IP checker	Open IP lookup ↗	Look up your current or supplied IP; inspect classification, operator and detection history. Public and API usage limits apply.
vpnapi.io	Public IP checker	Open VPN detection test ↗	Check the current or entered IP and compare the VPN result after reconnecting. Free test limits apply; production API usage follows the chosen plan.
IPHub	Public IP checker	Open IPHub lookup ↗	Use the guest lookup and compare the IP classification. Residential-proxy detail has separate limits and Pro access conditions.
IP2Location / IP2Proxy	Public IP lookup	Open IP2Location / IP2Proxy demo ↗	Inspect the exit IP, location and IP2Proxy classification. The demo does not establish access to every database package or production API field.
Abstract API	Public IP checker	Open free VPN checker ↗	Submit an IP to inspect its VPN and network result. Daily public credits are limited; further tests may require a free account.

How to compare a connection with and without a VPN

Open a checker with the VPN disconnected and record the public IP, classification and time.
Connect the VPN, reload the checker and repeat the same test. For a browser demo, repeat its demonstrated action too.
Compare the exit, network flags and any device/session result. Repeat with other exits and legitimate privacy connections before choosing a tool.

FAQ

Is this page an automatic VPN checker?

This is a directory of vendor tests. Open a linked checker to run a connection check; each vendor controls its data collection, available fields and usage limits.

Does a negative VPN result prove the whole device is protected?

No. A classification result describes the request a checker sees. Use the IP, DNS and browser checklist to inspect the applications and network paths you intend to cover.

How should I compare the demos?

Repeat the same action with the VPN disconnected and connected, record the exit and output, then repeat across relevant environments. The deployment guide explains a broader pilot.

FAQ

Can a VPN checker confirm that every application uses the VPN?

A browser test observes its own request and exposed browser surfaces. Check the applications, DNS path and IPv4/IPv6 configuration you intend to protect; one negative VPN flag does not establish complete coverage.

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.
