Does Your VPN
Actually Work?
Free browser tests for DNS, IPv6 and WebRTC leaks, IP exposure, speed and your kill switch - measured on your own connection.
No affiliate links, no VPN for sale, no paid placement. How we measure
6 VPN Tests - All Free
Every test runs directly in your browser. No downloads, no accounts needed.
VPN Leak Test
Check if your real IPv4, IPv6 and DNS are exposed even with VPN active.
Speed Test
Measure your VPN download speed, upload, ping, and jitter in real time.
DNS Leak Test
Verify your DNS queries are routing through VPN servers - not your ISP.
Kill Switch Test
Monitor your IPv4 live. Force-quit your VPN app to see if the kill switch holds.
Encryption Check
The TLS version and key exchange your browser negotiated with this site - read from the session, not assumed.
WebRTC Leak Test
Browsers can bypass VPNs via WebRTC - check if your real IP is exposed.
Privacy & Anonymity Tests
Go beyond IP leaks - test your browser fingerprint, trackers, and whether sites can detect your VPN.
Browser Fingerprint Test
Reads Canvas, WebGL, fonts, audio and more, and scores how many tracking signals your browser exposes.
Tracker & Cookie Scanner
Scans cookies, localStorage, DNT signals, and fingerprinting APIs available to tracker scripts.
WebRTC Leak Test (Extended)
Asks two STUN servers (Google, Cloudflare) - detects public IP leaks, IPv6 exposure and mDNS behaviour.
IPv6 Leak Test
Dedicated IPv6 test via both HTTP and WebRTC. A VPN that carries only IPv4 can leave IPv6 going around it - check yours.
VPN / Proxy Detection
How sites classify your IP address: on datacenter or proxy lists, or not, from two independent sources.
Network & Security Checks
DNS encryption, email authentication, password safety, and IP reputation - all free, all in the browser.
Encrypted DNS Check
Whether Cloudflare, Google and Quad9 DNS-over-HTTPS are reachable from your network.
Email Security Check
Check SPF and DMARC for any domain, and DKIM at twelve common selectors. Find out if it can be spoofed for phishing.
Password Strength
Check entropy, crack time, and whether your password appeared in known data breaches via HIBP.
IP Reputation Check
Check your IPv4 address against the spam blocklists that answer public DNS queries.

VPN Leak Rates From Shared Tests
Measurements visitors chose to share - not vendor claims. A provider appears once it has 30 results.
No provider has enough results yet
Every figure here comes from a test someone ran and chose to share, and a provider stays unpublished until it reaches 30 of them. Until then this section stays empty on purpose - an average built from a handful of runs is exactly the kind of number this database exists to replace.
