About ping123.app
ping123.app helps people see what their browser and network reveal before they trust a VPN, proxy, public Wi-Fi, or important login session.
Why this site exists
Most people only notice IP problems after something goes wrong.
A VPN may show one country while WebRTC exposes another signal. A proxy may work for browsing but still look risky during account login. A browser update can change DNS, language, timezone, or fingerprint behavior without making it obvious.
We built ping123.app for that ordinary but important moment before you sign in, travel, switch networks, use public Wi-Fi, or test a new VPN route. It gives you one calm place to compare your public IP, browser leak checks, DNS clues, fingerprint hints, and IP risk labels.
We do not promise anonymity. We help you see the evidence a website can see, explain the limits clearly, and make a better decision about whether the current browser session is safe enough for what you are about to do.
What we provide
Practical tools for everyday privacy checks
The service is designed for VPN users, proxy users, remote workers, travelers, and anyone who wants to understand what a website can see before continuing.
Manual leak tests
Run WebRTC, DNS, and browser fingerprint checks only when you choose, then compare the results against your expected VPN or proxy setup.
IP risk lookup
Review rule-based risk clues such as hosting networks, proxy-like organizations, shared IP patterns, native IP hints, and country or timezone mismatches.
Plain-language guides
Read practical guides about IP leaks, VPN checks, WebRTC, DNS, proxy risk, and account safety without exaggerated security promises.
Team
The people behind ping123
We are a small product team building a simple privacy utility: useful enough for technical users, calm enough for everyday users.
Ryan Chen
Founder & Lead Developer
Taiwan
Ryan started ping123 after seeing how often VPN and leak-test results were explained in a way that scared people instead of helping them. He works on the product direction, Worker API, and browser checks.
Mia Chen
Frontend Engineer & UI Designer
Remote
Mia turns network signals into a page people can actually read. She focuses on clear states, careful spacing, and making each manual check feel intentional.
Lucas Wang
Backend & Security Engineer
Remote
Lucas keeps the server-side boundary boring in the best way. He works on Cloudflare Worker behavior, defensive defaults, and keeping raw browser-side details visible to the user.
Emma Lin
Community & Product Manager
Remote
Emma listens for the confusing moments: a strange result, a mismatched country, a login warning, or a user who is not sure what to check next. She turns that feedback into product priorities and guides.
How we keep it practical
Free to use, clear about the tradeoffs
ping123.app is a small public service. We keep the checks free, document external service boundaries, and separate monetization from the actual test logic.
Fast global checks
Runs /api/check on page load and when the user refreshes the IP profile, then provides free GeoIP fields from Cloudflare request metadata.
Product analytics
GA4 helps us understand which languages, guides, and checks are useful so we can improve the service.
Readable location context
When location fields are available, map tiles make the result easier to understand without turning the check into a tracking promise.
Ads and affiliate links
Ads and partner links support free access, but they do not decide your IP result, leak result, or risk label.
