Browser Privacy Tools
See exactly what your browser reveals to every site you visit — your fingerprint, IPs, DNS queries, headers and location. Free, no signup.
What your browser tells about you
Every page you load sees more than your IP. These tools expose one layer at a time — the full fingerprint, the IPs you leak, the resolvers you ask, the strings and headers you send, and where your browser says you are.
Fingerprint Checker
Full scan of what your browser exposes: canvas, WebGL, audio, fonts, hardware and consistency checks with a coherence score.
Open tool →What Is My IP
Your public IP, location, ISP and ASN — plus a VPN, proxy and datacenter verdict and a WebRTC cross-check.
Open tool →WebRTC & DNS Leak Test
Find the public IPs your browser exposes through WebRTC and every DNS resolver your traffic really uses.
Open tool →User-Agent Checker
Decode your user-agent string and Client Hints, with cross-checks that expose spoofed or tampered user agents.
Open tool →HTTP Header Checker
Inspect every header your browser just sent — with plain-English notes on what each one reveals.
Open tool →Tools.geolocationTitle
Tools.geolocationDesc
Open tool →Network & proxy tools
Test the connection itself: proxy health, exit IPs and how your traffic looks from the outside.
Fix what these tools reveal — with Antybrowser
Antybrowser gives every account its own isolated browser profile: unique fingerprint, per-profile proxy and separate cookies. What these free tools reveal, the desktop app controls.
Frequently asked questions
Are these browser privacy tools free?
Yes — every tool on this page is free and needs no account: IP & VPN detection, WebRTC/DNS leak test, fingerprint checker, user-agent decoder, HTTP header checker, geolocation check and the proxy checker. Desktop-app features like the unlimited bulk proxy checker are part of paid Antybrowser plans.
What data do the tools collect?
Each run stores a 30-day report (so share links work) keyed by a salted hash of your IP — raw IPs are never stored, credential headers and proxy credentials are stripped before storage. The tools exist to show you what the web sees; they don't build profiles of you.
What is an anti-detect browser and why would I need these tools?
An anti-detect browser (like Antybrowser) runs each account in an isolated profile with its own fingerprint, cookies and proxy. These free tools let you verify what a website would actually see from your current setup — before you trust it with real accounts.
Do I need the desktop app to use these?
No. All tools run in your current browser. The Antybrowser desktop app goes further: it creates and manages multiple isolated browser profiles, applies per-profile fingerprints and proxies, and includes an unlimited bulk proxy checker.
