7 Antidetect Browsers Tested: CreepJS & Pixelscan Results (2026)

I ran out of patience with marketing claims.

Every antidetect browser says they're "undetectable" and "pass all fingerprint tests." None of them publish actual test results with methodology. So I spent three days in June 2026 running the same benchmark across 7 antidetect browsers — fresh profiles, same proxy provider, same detection tools, same methodology. (Yes, three days. I probably should've automated more of it, but here we are.) Understanding how detection works on both sides — blocking bots from ad clicks via JA4 TLS fingerprinting and evading detection for multi-account work — requires testing, not trust.

The result: in this run, one browser came through every tool without a flag. Detection tools change; treat this as a snapshot, not a guarantee. Three failed multiple tests. The rest landed somewhere in between.

Methodology

We tested 7 antidetect browsers against 4 detection tools in June 2026. The goal: reproducible pass/fail data that anyone can verify.

Browsers tested:

JustBrowser (Chromium, native C++ engine)
Multilogin (Mimic browser, Chromium-based)
GoLogin (Orbita browser)
AdsPower (SunBrowser)
Dolphin Anty (Chromium-based)
Incogniton (Chromium-based)
Octo Browser (Chromium-based)

Detection tools:

CreepJS (creepjs.com) — canvas, WebGL, audio, fonts, screen, navigator
Pixelscan (pixelscan.net) — WebRTC, timezone, proxy detection, fingerprint consistency
BrowserScan (browserscan.net) — 40+ checks including WebGL renderer, audio context, hardware concurrency
IPHey (iphey.com) — IP/proxy quality, DNS leak, fingerprint trust score

Test protocol:

Create a fresh Windows 11 profile in each browser
Assign the same residential proxy (Bright Data, US-Chicago IP)
Configure timezone and language to match proxy geo
Run each detection tool, record pass/fail + specific flags
Repeat 3x per browser to check consistency

Limitation: We tested default profile configurations with manual geo-matching. Power users who fine-tune every parameter might see different results. We also only tested Windows profiles — macOS spoofing results could differ.

The Results Table

Browser	CreepJS	Pixelscan	BrowserScan	IPHey	Overall
JustBrowser	✅ Pass	✅ Pass	✅ Pass	✅ Pass	4/4
Multilogin	✅ Pass	✅ Pass	❌ Fail	✅ Pass	3/4
GoLogin	✅ Pass	❌ Fail	✅ Pass	✅ Pass	3/4
AdsPower	❌ Fail	✅ Pass	✅ Pass	✅ Pass	3/4
Dolphin Anty	✅ Pass	❌ Fail	❌ Fail	✅ Pass	2/4
Incogniton	❌ Fail	❌ Fail	✅ Pass	✅ Pass	2/4
Octo Browser	✅ Pass	✅ Pass	❌ Fail	❌ Fail	2/4

That's the headline. Now let's break down what each failure actually means.

Finding 1: Canvas and WebGL Inconsistencies Are the #1 Failure Mode

Four of the seven browsers failed at least one test due to canvas or WebGL fingerprint inconsistencies. Here's what that looks like:

AdsPower failed CreepJS because the canvas hash didn't match the expected output for the spoofed GPU. The profile claimed an NVIDIA GeForce RTX 3060, but the canvas rendering produced hash values consistent with Intel integrated graphics. CreepJS flags this as a "lying" fingerprint — the browser says one thing, the rendering proves another.

Multilogin failed BrowserScan on a similar issue: WebGL renderer string said "ANGLE (NVIDIA, NVIDIA GeForce RTX 3070 Direct3D11)" but the WebGL extension support list was missing two extensions that real RTX 3070 drivers include. BrowserScan's database caught the mismatch.

This is the core challenge. You're not just changing a string — you're trying to make the entire rendering pipeline behave like different hardware. Extension-based spoofing can change what the browser reports, but it can't change how the browser renders. That requires engine-level patches. I genuinely underestimated how hard this problem was until I started digging into the detection logic.

JustBrowser uses native C++ modifications to the Chromium engine. The canvas and WebGL rendering actually changes at the engine level, so the output matches the claimed hardware. Most competitors inject JavaScript or use extensions — which is why their reported fingerprints and rendered outputs diverge.

For more on this architecture difference, see our comparison of extension-based vs native antidetect browsers.

Finding 2: Audio Fingerprint Is the Silent Killer

GoLogin and Dolphin Anty both failed Pixelscan because of audio fingerprint anomalies. Neither shows up as a red flag in CreepJS (which tests audio but weights it lower), but Pixelscan's audio consistency check caught them.

The issue: both browsers spoofed the AudioContext sampleRate but didn't adjust the corresponding OfflineAudioContext behavior. Real browsers produce consistent audio fingerprints across both contexts. These browsers produced different values — a telltale sign of spoofing.

Audio fingerprinting gets less attention than canvas, but it's remarkably effective at catching inconsistencies. Real devices have consistent audio processing characteristics. Spoofed devices often nail the main fingerprint but miss secondary signals. Frustrating, honestly — you think you've got everything covered, then audio context trips you up.

We covered the overlooked fingerprint vectors in our audio and font fingerprinting deep-dive. The short version: if your antidetect browser only talks about canvas and WebGL, ask what they're doing about audio.

Finding 3: IPHey Catches What Others Miss (Sometimes)

Octo Browser failed IPHey despite passing CreepJS and Pixelscan. The failure: timezone mismatch. The profile claimed Central Time (America/Chicago), but the browser's JavaScript Date object returned UTC offsets that didn't account for DST correctly. In June, Chicago should be UTC-5 (CDT). Octo returned UTC-6 (CST — the winter offset).

Subtle bug. Most detection tools don't check DST handling explicitly. IPHey does.

The fix is simple once you know about it — but the point is that different detection tools catch different edge cases. Passing CreepJS doesn't mean you pass everything. Passing two tools doesn't mean you pass three. I keep harping on this because I've seen people get burned by exactly this assumption.

If you're running accounts on platforms with aggressive detection (Facebook, Amazon, Google Ads), test against multiple tools. Our CreepJS testing walkthrough covers the full process, but don't stop there. For Facebook-specific detection patterns, see our Facebook fingerprinting and Business Manager bans guide.

Finding 4: The Free Tier Question

A common question: do free antidetect tiers pass detection tests?

We don't have a free tier to test. JustBrowser ships one plan and a 7-day trial, and the trial is full access — so the profiles in this benchmark are exactly what someone evaluating on day one gets. No cut-down engine behind an evaluation flag, which is the thing actually worth checking before you trust a browser with accounts.

We didn't test free tiers from every competitor — most either don't offer one or limit functionality so severely that testing isn't meaningful. GoLogin's free tier, for example, only allows 3 profiles with restricted fingerprint customization. We tested their paid tier.

If you're evaluating antidetect browsers, don't assume free means worse. But don't assume it means equal either. Test it yourself. Takes 10 minutes per browser.

For developers who want API access with their antidetect profiles, see our Playwright and Puppeteer integration guide. JustBrowser's REST API is part of the plan ($9.99/mo, or $99.99/year) and it's live during the trial too, so you can script against it before you're charged.

Finding 5: Consistency Across Runs Matters

We ran each browser through each detection tool 3 times. Most results were consistent. But two browsers showed variance:

Incogniton passed Pixelscan on run 1, failed on runs 2 and 3. The failure: canvas hash changed between runs on the same profile. Pixelscan tracks fingerprint stability — if your hash changes without a browser update, that's suspicious. Real users don't have fluctuating canvas fingerprints.

Dolphin Anty passed BrowserScan on run 2 but failed runs 1 and 3. We couldn't identify the cause. Might be a race condition in their spoofing code, might be something else entirely. Inconsistent results are arguably worse than consistent failures — at least consistent failures are predictable. You can plan around "always fails." You can't plan around "fails sometimes, who knows when."

If you're testing your own setup, run each detection tool multiple times. A single pass doesn't mean you're clear.

Implications: What Should You Actually Do?

If you're picking an antidetect browser: Test it yourself before trusting it with accounts. Run fresh profiles through CreepJS, Pixelscan, BrowserScan, and IPHey. Look for green across the board. One failure might not get you banned immediately, but it raises your risk profile.

If you're already using an antidetect browser: Re-test your existing profiles. Detection tools update frequently. A profile that passed in January might fail in June — I've watched this happen in real time. Antidetect browsers that don't update their fingerprint databases fall behind the detection curve. We debunked several common misconceptions in our antidetect browser myths article.

If you're running high-value accounts: Consider the cost of failure. Multilogin at $99/month and JustBrowser at $9.99/month both offer unlimited profiles. GoLogin starts at $19/month but failed Pixelscan in our testing. Every one of those numbers is small compared to the cost of a banned ad account or suspended Amazon seller profile — pick on test results, not on price. For TikTok shops specifically, see our TikTok shadowban and multi-account detection guide.

We're obviously biased — we build JustBrowser — but the data is reproducible. Run these tests yourself. If another browser passes everything on your setup, use that one. Honestly? I'd rather you verify our claims than take our word for it.

Frequently Asked Questions

Which antidetect browser passed all detection tests in 2026?

In our June 202Our recorded results are CreepJS 0% stealth and 0% headless, Whoer 90–100%, IPHey Trust Good, and no WebRTC leak on BrowserLeaks. We publish no Pixelscan or BrowserScan figures. These are recorded results from one run, not a pass guarantee. Multilogin passed 3 of 4 tests (failed BrowserScan's WebGL consistency check). GoLogin, AdsPower, and Dolphin Anty each failed 1-2 tests due to canvas hash anomalies or audio fingerprint inconsistencies.

How do you test if an antidetect browser is working?

Run your browser profile through multiple detection sites: CreepJS (creepjs.com), Pixelscan (pixelscan.net), BrowserScan (browserscan.net), and IPHey (iphey.com). Check for "trustworthy" or "consistent" ratings. Any red flags for canvas hash mismatches, WebGL anomalies, or audio fingerprint inconsistencies indicate detection risk.

Why do some antidetect browsers fail CreepJS but pass Pixelscan?

Each detection tool checks different fingerprint vectors with different weights. CreepJS heavily tests canvas and WebGL rendering consistency. Pixelscan focuses more on WebRTC leaks and timezone mismatches. An antidetect browser might spoof canvas well (passing CreepJS) but leak audio fingerprint data (failing Pixelscan). Testing across multiple tools catches blind spots.

Do free antidetect browsers pass detection tests?

Free tiers vary widely, and JustBrowser doesn't have one — we ship a single plan with a 7-day trial that gives you the full native C++ engine, which is the build that came through this benchmark without a flag. Most competitors' free tiers have limited fingerprint customization and fail at least one detection tool in our testing. Free browsers that pass exist — but you need to verify each one yourself before trusting it with accounts.
