Pick BrowserLeaks first, then use IPLeak.net and DNSLeakTest.com to double-check your VPN or proxy. That trio catches the usual mess: IP leaks, DNS leaks, WebRTC leaks, and weird browser clues. WebRTC is a real browser feature for live audio and video, so it is useful, but it can also expose details you did not expect [source: MDN]. If Whoer gives you one big score and you want clearer proof, these six services are better for spot checks.
TLDR: Use BrowserLeaks for deep browser checks, IPLeak.net for VPN leaks, and DNSLeakTest.com for DNS issues. If you have 10 minutes, run 3 tests: IP, DNS, and WebRTC. Example: turn on a VPN in Germany; if 2 of 3 tools still show your home ISP, something is broken. For most people, these checks catch the big privacy leaks fast.
1. BrowserLeaks
Best for: browser fingerprint checks.
BrowserLeaks is the nerdy one. In a good way. It checks WebRTC, canvas, fonts, audio, location, user agent, and more. That means it can show how “unique” your browser looks.
The page is packed with data. Honestly, it feels like opening a toolbox and finding 47 tiny screwdrivers. Useful, but a bit much.
- Use it when: you want the full browser picture.
- Check: WebRTC IP, canvas, fonts, timezone, user agent.
- Annoyance: some results need tech knowledge.
2. IPLeak.net
Best for: quick VPN leak testing.
IPLeak.net is simple. Open it. Wait a few seconds. Read the results. It checks your visible IP, DNS servers, WebRTC, and sometimes torrent address leaks.
This is great before using a VPN for anything private. Start your VPN. Open IPLeak.net. Your real country and ISP should not appear.
- Use it when: you just changed VPN servers.
- Check: IP address, DNS list, WebRTC result.
- Annoyance: the page can feel plain and old.
3. DNSLeakTest.com
Best for: DNS leak checks.
DNS is like the phonebook of the web. When you type a site name, DNS helps find it. If your VPN is on but DNS still goes through your normal internet provider, that is a leak.
DNSLeakTest.com keeps things clean. You can run a standard test or an extended test. The extended test takes longer, but it gives a better view.
It drives me crazy when privacy tools hide the simple answer. This one does not. If you see your ISP, fix your VPN settings.
4. EFF Cover Your Tracks
Best for: tracker and fingerprint protection checks.
Cover Your Tracks comes from the Electronic Frontier Foundation. It tests how well your browser blocks trackers. It also checks if your browser fingerprint is common or rare.
A rare fingerprint can be bad. It means you stand out. Like wearing a banana costume at a tax office.
EFF says the tool checks tracking protection and fingerprinting behavior [source: EFF].
- Use it when: you use ad blockers or privacy extensions.
- Check: tracker blocking and fingerprint uniqueness.
- Annoyance: results can sound scary without context.
5. CreepJS
Best for: seeing how creepy fingerprinting gets.
CreepJS is not cute. It shows how much a site may learn from your browser. It checks screen size, graphics, audio, fonts, hardware hints, and more.
This tool is great if you use Brave, Firefox, Tor Browser, or privacy extensions. Run it once. Change a setting. Run it again. See what changed.
Expect to waste time on tiny details. One setting can shift the result. Then you start chasing ghosts. Still, it is a strong reality check.
6. WhatIsMyIPAddress.com
Best for: simple IP and location checks.
This site is easy for beginners. It shows your IP, rough location, ISP, and sometimes proxy or blacklist notes. It is not as deep as BrowserLeaks. That is fine.
Use it when you need a fast sanity check. Does your VPN show the right country? Does your ISP still appear? Is the location wildly wrong? This tool answers those questions fast.
- Use it when: you want a plain English IP check.
- Check: IP, ISP, location, proxy status.
- Annoyance: ads can get in the way.
Quick test plan
- Turn off your VPN. Run one test. Note your real IP and ISP.
- Turn on your VPN. Pick a faraway country.
- Open IPLeak.net. Your real ISP should be gone.
- Run DNSLeakTest.com. Use the extended test.
- Open BrowserLeaks. Check WebRTC and fingerprint clues.
- Try Cover Your Tracks. See if trackers are blocked.
Which one should you use?
If you want one tool, choose BrowserLeaks. If you want a fast VPN check, use IPLeak.net. If pages load fine but privacy feels off, use DNSLeakTest.com.
For browser fingerprints, use Cover Your Tracks and CreepJS. For a simple “what IP am I showing?” check, use WhatIsMyIPAddress.com.
No single test is magic. Run two or three. If they all agree, you can relax a bit. If they disagree, your browser, VPN, or DNS settings need attention.
