WebRTC Leak Test

Run a free WebRTC leak test to check whether your browser exposes your real public IP, local IP, IPv6 address, or mDNS candidate while using a VPN or proxy

Overview

Check if WebRTC exposes your real IP

The test runs automatically in your browser and compares your HTTP connection with WebRTC candidates to detect possible IP leaks

WebRTC and your HTTP exit IP take the same path. No separate identity is exposed.

WebRTC is a browser technology that allows direct audio, video, and data connections between users. To create those connections, the browser collects ICE candidates, which can include public IPs, local network IPs, IPv6 addresses, and mDNS candidates.

The issue is that WebRTC can use browser network interfaces separately from your normal web connection. That means your website traffic may go through a VPN or proxy, while WebRTC still reveals another IP path.

Designed for the job

Use the result, then tune the route

Run the check, note what it exposes, and use the result to decide whether the proxy, browser, or DNS configuration needs adjustment.

Run

Use the tool with the exact proxy or browser configuration you want to evaluate.

Interpret

Separate a network finding from a browser, DNS, or destination-specific behavior.

Adjust

Change one variable at a time, then run the check again to verify the improvement.

Deep dive

What is a WebRTC leak?

For proxy users, the fix is usually in the browser, anti-detect profile, or automation setup, not only in the proxy itself.

Yes. A proxy can route normal HTTP or SOCKS5 traffic correctly while WebRTC still uses the browser’s network interfaces. Gateproxies proxies support HTTPS and SOCKS5, but WebRTC protection depends on your browser, anti-detect profile, or automation setup.

WebRTC uses ICE candidates to find possible network paths for peer-to-peer connections. If your browser is not configured correctly, those candidates can reveal IP information outside your VPN or proxy tunnel

The website runs JavaScript that creates an RTCPeerConnection in your browser

Workflow

Can WebRTC leak when using proxies?

01 · Run the diagnostic

Run the diagnostic with the intended setup.

02 · Read the signal

Read the signal the tool actually measured.

03 · Check the environment

Check whether browser, proxy, or DNS context changes it.

04 · Change one variable

Change one variable at a time.

05 · Run it again

Run the test again to verify the result.

06 · Keep the verified setup

Keep the verified setup available for later checks.

Details

How WebRTC exposes your IP

Run the check against a known route, read the result, and adjust the setup only when the evidence points to a change.

Keep credentials private and use the support channel when the result is unclear.

Practical guidance

Interpret the result carefully

A diagnostic is a decision aid. It should tell you what to investigate next, not promise a universal answer.

Signal

Identify what the tool actually measured.

Context

Compare it with the browser, proxy, and destination setup.

Make one controlled change and test again.

FAQ

FAQs

Yes. Pick residential, mobile, or ISP Premium based on risk and session needs, then point your tool at the proxy host from the dashboard.

Residential and mobile use per-GB packages (billed monthly or pay as you go). ISP Premium is priced per IP. There are no free unlimited plans.

HTTPS works for most browser and scraper stacks. SOCKS5 is available when your tool prefers it.

Yes on eligible products. Hold the same IP for multi-step flows, or rotate per request for bulk collection.
