The Problem
Every time you browse the internet, your real IP address, DNS queries, and browser fingerprint are potentially exposed — even when you're using a VPN.
Most tools out there are either:
- Paid
- Cluttered with ads
- Only checking one thing at a time
I built IPOK to solve this.
What is IPOK?
IPOK is a free, privacy-focused network diagnostics platform that checks:
- Public IP address — What does the internet see when you visit?
- DNS Leak Test — Is your VPN actually protecting your DNS queries?
- WebRTC Leak Test — Is your real IP leaking through WebRTC?
- TLS Fingerprint — How unique is your TLS handshake?
- Browser Fingerprint — Canvas, WebGL, fonts, audio, storage
- IP Type Detection — Is your IP a datacenter, VPN, or residential?
All in one place. No ads. No registration. Instant results.
Why I Built This
I wanted a tool that:
- Works entirely in the browser (no server-side tracking)
- Checks multiple privacy signals at once
- Supports 4 languages (EN, 中文, 日本語, Русский)
Tools Overview
Network & Connectivity
- DNS Lookup & Network Overview
- DNS Integrity Check (multi-resolver consistency)
- TLS Fingerprint & HTTP/3 Test
- IP Type Detection (Datacenter/VPN/Proxy)
- WebRTC Leak Test
Security & Privacy
- Security Headers Test (CSP, HSTS, X-Frame-Options)
- Browser Privacy Test (permissions & automation signals)
- Browser Consistency Test (timezone, language, locale)
Browser Fingerprint
- User Agent Parser
- Canvas & WebGL Fingerprint
- Browser Environment (fonts, audio, storage)
- Browser Features Support
Open Source
The project is built with Next.js and deployed on Cloudflare, with a focus on privacy-first design. All checks run client-side — your data never touches our servers.
