Multilogin vs GoLogin vs Dolphin Anty: An Honest Comparison

The View from the Other Side

You're shelling out $99 a month for an antidetect browser. Fire up IPhey. Green checkmarks everywhere. PixelScan. Green again. CreepJS hands you a trust score of 85%. Ghostlike, you reckon.

Here's what our side sees.

Your GPU crunched that shader 0.3ms faster than the profile claims. Mouse acceleration matches a pattern we've flagged 47 times this week from the same Multilogin build. Your TLS Client Hello carries cipher suites that haven't shipped in any real Chrome since version 118. HTTP/2 SETTINGS frame lands in macOS order, yet the profile insists Windows.

Green checkmarks. Red handcuffs.

Nobody should mistake this for an antidetect browser review. Web's awash in those, all penned by folks who either sell these tools or earn affiliate kickbacks. We build WHOX. We get paid to unmask these browsers. Picture a cop sizing up three popular disguises.

TL;DR

Multilogin, GoLogin, and Dolphin Anty spoof 300+ browser fingerprint parameters and glide through the popular checkers. All three fold before hardware GPU timing, TLS fingerprinting, behavioral analysis, and CSS fingerprinting. Gaps between them are real, yet the ceiling is shared. Serious anti-fraud on your adversary's end? None of these will shield you. Cookie-and-IP-level checking only? Any of them gets the job done.

Multilogin stands as the oldest and the priciest. Only one offering a Firefox core called Stealthfox. GoLogin reaches the widest audience and remains the sole option backing Linux, Android, and cloud profiles. Dolphin Anty arrived latest and hits hardest on automation: cookie robot, scenarios, bulk ops, Playwright hookups.

Facts. No verdicts yet. Verdicts come further down, and they'll sting.

How Antidetects Work in 30 Seconds

An antidetect browser profile bundles spoofed parameters. Canvas noise, WebGL renderer, User-Agent, screen resolution, timezone, languages, fonts, CPU core count, memory size, WebRTC config. Roughly 300 parameters all telling one seamless story.

Sounds straightforward. In practice, holding up under cross-examination would be a stroll by comparison: you've got to recall every thread of every earlier lie, three hundred of them, without tripping once. One slip and the whole confection unravels.

Canvas says GTX 1080 while the WebGL renderer hands back Angle Intel UHD 630? Caught. Timezone reads America/New_York while Intl.DateTimeFormat resolves to Europe/Moscow? Caught. navigator.hardwareConcurrency = 8 while performance.now() betrays single-threaded timing? Caught.

300 parameters. One mistake. Math hates the attacker.

Bedrock lopsidedness of the entire antidetect trade lives right there. Attackers must flawlessly spoof every signal out of three hundred. Defenders need a single fissure. Canvas noise with the wrong statistical spread? Caught. WebGL vendor drifts from the WebGPU adapter? Caught. Mouse movement too smooth, too algorithmic? Caught. Attackers must be immaculate across every axis while defenders need one hairline crack.

Antidetects are always trailing. Always.

What They Can't Spoof

Here's where the glossy marketing comparisons go mute. Long section ahead, and with good reason: the catalogue of what antidetects can't do dwarfs the list of things they can.

Hardware Timing

Your GPU runs shader computations at latencies unique to the specific silicon die. Not the model line. Specific physical chip on your desk. Drawnapart, published at NDSS 2022, showed manufacturing variance in silicon yields a stable fingerprint no software on earth can spoof.

All three antidetects run on your real hardware. Profile says GTX 1080 in Berlin, yet GPU timing, tracked as F21 inside WHOX, answers: Apple M2, same as yesterday, same as the day before. Neither Multilogin on its top tier nor free GoLogin can bend this. Software doesn't override physics. Never has, never will.

Prototype Chains and CDP Markers

V8 keeps telltale signatures in object prototype chains. Blink renders pages in a fixed order. Chrome DevTools Protocol leaves traces even when DevTools sit closed. Error stack trace formats betray the engine underneath, an inescapable quiddity no mask can hide.

WHOX checks this through C48 for prototype integrity, C49 for Proxy traps, and C50 for global pollution plus CDP markers. Antidetect patches navigator.webdriver? Fine. C48 spots the swapped function by catching behavioral drift from the native build.

TLS Fingerprint

When a browser opens an HTTPS link, it sends a TLS Client Hello carrying cipher suites, extensions, and a fixed parameter ordering. Fingerprint takes shape at the network stack level, not the browser level.

JA4/JA3 fingerprint, labeled A05 in WHOX, hits the server before a single line of JavaScript runs. Antidetect spoofs User-Agent to Chrome 122 on Windows? Lovely. TLS Client Hello still ships with extensions native to Chromium on macOS. Server clocks the mismatch before the page even loads.

HTTP/2 SETTINGS

Parameter order in HTTP/2 SETTINGS frames differs between operating systems and network stacks. Tracked as A18 in WHOX. Antidetects don't control this. Don't try to. Most don't even know someone's watching.

Behavioral Patterns

Typing cadence. Mouse arc. Scroll rhythm. Speeding up, slowing down. All of it weaves a behavioral fingerprint lashed to a specific human, not a profile. Multilogin can spoof resolution and fonts. Can't spoof your reflex of jerking the mouse right before a click.

The Checker Palaver

Standard day for an antidetect user. Build a profile. Open IPhey. 30 checks. All green. Open PixelScan. 5 items. All green. Satisfied. Off to work.

Here's the snag: IPhey tests about 30 parameters. PixelScan tests 5. CreepJS, the most assiduous public checker, tests roughly 100 and spits out a trust score. All three run solely on the client side, in JavaScript.

WHOX tests 126+ parameters along three axes: fingerprint, consistency, architecture. On top of that come server-side signals: JA4 TLS, HTTP/2 SETTINGS, edge RTT. Browser Polygraph from IMC 2024, built by teams at BU and Arizona State, wields ML on coarse signals at web scale. Fingerprint.com runs its own proprietary deep checks.

Antidetect browsers tune themselves for the checkers their users run. Not for the detection rigs their targets deploy. A burglar drilling on a toy safe. Feels good until you meet the vault.

WWW 2025 research from LSU puts it flatly: no fully deployable canvas defense exists today. 18 extensions and 5 privacy browsers tested. Canvas randomization beaten in every case. Every single one.

NDSS 2025's Cascading Spy Sheets paper from CISPA showed CSS-only fingerprinting hitting 97.95% accuracy across 1,176 browser-OS combos. No JavaScript needed at all. Antidetects pour their entire craft into JS-level spoofing. Don't touch CSS rendering behavior whatsoever. Two whole attack surfaces where all three browsers stand naked and defenceless.

What WHOX Sees

Enough abstractions. Brass tacks.

WHOX's antidetect module spots the type, whether browser or extension or automation tool; the specific name; a confidence score from 0.0 to 1.0; and a roster of triggered markers. Draws on integrity checks, CDP markers, engine traps, vendor flavor signatures, headless detection, canvas/WebGL/audio integrity, screen/font/mobile consistency, and privacy mode patterns.

Multilogin gets flagged at an average confidence of 0.7 to 0.85. Mimic leaves telltale marks in prototype chains. Stealthfox is thornier: Gecko is a genuinely different engine, and C11, the engine integrity check, doesn't fire on the Chromium-as-Chrome mismatch. Gecko carries its own quiddity, though, and vendor flavor detection ferrets it out. Costlier mask, sure. Still visible.

GoLogin lands at 0.75 to 0.9. Orbita is Chromium underneath, and deep engine signatures match what you'd expect from a patched Chromium build. Characteristic tweaks in the navigator API. Specific canvas substitution patterns. On some hardware GoLogin falls back to real device traits, which, by a strange irony, sometimes helps: fewer spoofs means fewer artifacts. When it does spoof, we see it.

Dolphin Anty lands at 0.8 to 0.95. Youngest of the three. Least burnished. Chief strength, automation through Selenium, Puppeteer, and Playwright, doubles as chief liability: automation leaves indelible traces. C50 catches CDP hookup signs. Scenarios and the synchronizer breed behavioral patterns that look nothing like human input. GoLogin wasn't bluffing when they claimed IPhey catches Dolphin Anty. IPhey catches GoLogin too. Just different tripwires.

The Chromium Trap

All three browsers sit on top of Chromium. Multilogin offers Stealthfox as a Firefox/Gecko offshoot, yet most users pick Mimic, the Chromium branch.

Why that's a problem: Chromium isn't just a renderer. An entire ecosystem hums underneath: V8, Blink, a fixed object startup order, an unmistakable Error.stack format, deterministic prototype chains. You can stir noise into canvas. Can't rewire how V8 handles object prototypes or how Blink reckons layout.

Browser Polygraph from IMC 2024 is built squarely on this insight. Coarse signals: prototype chains, stack trace signatures, timing patterns. No need to match 300 parameters. Just watch how the engine behaves at a substratal level.

Three antidetects painted Chromium different hues. Under the paint sits the same engine. And we aren't checking the color.

Team Sharing Is a Security Hole

All three sell shared profiles. Marketing pitch: share profiles with your team!

Hard truth follows. A profile is set to Windows 10, GTX 1080, 1920x1080. Teammate A opens it on a MacBook M2. Teammate B fires it up on a Linux rig with Intel UHD 630.

GPU compute timing via F21 lays bare the real hardware. WASM timing via F22 lays bare the real hardware. Mouse and keyboard patterns lay bare the real human. One supposed user suddenly wields three different GPUs and three different typing speeds. Profile is a costume. Body underneath keeps bleeding through. When three people take turns wearing one costume, it's a pantomime nobody asked for.

USENIX 2025's Double-Edged Shield from CISPA stacks another wrinkle on top. Anyone on the team running a custom ad blocker shrinks the anonymity set to 48 people. Cooperative work through antidetects is cooperative deanonymization, whether you grasp it or not.

Price vs Quality: A Ceiling Nobody Can Buy Through

Multilogin at €99+ a month mostly churns out more watertight fingerprints than free-tier Dolphin Anty. Data bears this out, not guesswork. More engineers, a trove of real device fingerprints, the Stealthfox fallback.

Still, the ceiling is adamantine and shared. Drawnapart from NDSS 2022 works against any software-level spoofing. GPU timing shows real hardware regardless of subscription tier. CSS fingerprinting per NDSS 2025 works without JavaScript. Server-side signals like JA4 and HTTP/2 SETTINGS form before the antidetect loads a single masking script.

You can buy a sharper disguise. You can't buy a new skeleton.

Who Should Use What

Let's be blunt. Not every reader here works in anti-fraud.

Your adversary checks cookies, IP, and basic fingerprinting, most social networks and small platforms fit that mold, and any of the three will work. GoLogin is the cheapest. Dolphin Anty wins on automation. Multilogin is the most polished.

Your adversary runs Fingerprint.com, WHOX, or an in-house anti-fraud stack at bank or ad-platform grade: none of the three will help. Question isn't which one is best. Question is what your adversary's budget looks like. Server-side TLS analysis, hardware timing, and ML detection on their end? You lost before the page loaded.

Middle ground exists. Up against a platform running workaday anti-fraud plus a CreepJS-grade checker? Here Multilogin brings the tightest consistency. GoLogin gives the best bang for the buck in resistance. Dolphin Anty stumbles first, owing to looser masking and automation residue.

Keep this in mind, though: any platform can bolster its anti-fraud tomorrow. Green checkmarks today guarantee nothing tomorrow. Anti-fraud world moves faster than the antidetect world. Deeper pockets, fed by ad platforms, banks, and marketplaces. More data. And an academic community shipping fresh detection methods every year. Four of the six papers cited in this piece came out in 2025. Four.

FAQ

Which antidetect browser is the safest? None. All three spoof JS-level parameters, and all three are helpless against hardware timing, TLS fingerprinting, and CSS fingerprinting. Multilogin is the most consistent. GoLogin is the most reachable. Dolphin Anty is the best for automation. Safest hinges entirely on what your adversary is running.

If I passed IPhey and PixelScan, am I invisible? No. IPhey checks about 30 client-side parameters. PixelScan checks 5. WHOX checks 126+ plus server-side signals that checkers never touch. Browser Polygraph from IMC 2024 catches antidetects on coarse signals through ML. Passing a checker means you passed a checker. Nothing more.

Why does Multilogin need Stealthfox when everyone uses Chromium? Because all three Chromium cores, Mimic, Orbita, and Dolphin's own, carry the same deep markers: V8 timing, Blink prototype chains, Error.stack format. Stealthfox on Gecko is a genuinely different engine with different behavior. C11 doesn't fire on the Chromium-as-Chrome mismatch. Gecko has its own markers, though, and vendor flavor detection finds them. A different set of problems, not an absence of problems.

My colleague uses the same profile from a different machine. Is that a problem? Yes. Profile spoofs what JavaScript sees. GPU timing via F21, WASM timing via F22, and behavioral patterns are all lashed to real hardware and a real human. When one supposed user suddenly has three different GPUs and three different typing speeds, it doesn't look like one person.

Can an antidetect browser spoof the TLS fingerprint? In theory, yes, by intercepting and rewriting the TLS Client Hello at the network stack level. In practice none of the three do it. JA4/JA3 fingerprint is shaped by the OS and the network library, not the browser. Swapping license plates but forgetting about the VIN.
