Antidetect Browser Detection

Catch every major antidetect browser.
One API. Sub-40 ms.

Antidetect browsers — Kameleo, GoLogin, Multilogin, AdsPower, Dolphin{anty}, Incogniton — generate unique device fingerprints per session and pair with residential proxies to look like real consumers. IP-reputation tools see "clean residential ISP" and let them through. Sentinel sees the tampering signature the antidetect engine can't hide.

KameleoDetected
The most-used antidetect browser among professional fraud rings. Custom Chromium fork with full canvas / WebGL / audio context spoofing. Sentinel detects it via tampering-score + residential-proxy correlation.

GoLoginDetected
Cloud-hosted antidetect with cross-platform browser profiles. Popular for affiliate fraud, ad fraud, and account farms. Detected via WebGL renderer mismatches + behavioural timing.
How we detect GoLogin →
MultiloginDetected
The original commercial antidetect, ships with both Mimic (Chromium) and Stealthfox (Firefox) variants. Detected through font-stack inconsistencies and audio-context fingerprint anomalies.
How we detect Multilogin →
AdsPowerDetected
Asia-Pacific market leader, heavy use in cross-border e-commerce and dropshipping fraud. Detected via canvas tampering signature plus residential-proxy ASN correlation.
How we detect AdsPower →
Dolphin{anty}Detected
Bookmaker / iGaming bonus-abuse favourite. Profile cloud-sync. Detected through TLS / JA3 fingerprint mismatch and session-replay device-ID drift.
How we detect Dolphin{anty} →
IncognitonDetected
Free-tier antidetect that draws lower-skill fraud operators. Often paired with rotating proxies. Detected through plugin-stack inconsistency and screen-resolution-vs-userAgent mismatch.

How antidetect detection actually works

Every antidetect browser ships with a tampering layer that overrides Chrome's default fingerprinting surface — canvas, WebGL renderer, audio context, font list, hardware concurrency, screen resolution, timezone, language. The point is to make each "profile" look like a different real device.

The catch: spoofing all of those signals consistently is genuinely hard. Real browsers have correlations (a Mac's WebGL renderer maps to specific GPU strings, fonts available depend on OS version, etc.). Antidetect tools cut corners. Sentinel runs a consistency check across 40+ low-entropy signals, and the tampering score lights up when they don't add up.

Canvas tampering
Bezier-curve aliasing, sub-pixel positioning, and emoji rendering deviate from real GPU output in measurable ways.
WebGL parameter mismatch
Claimed GPU string doesn't match the underlying renderer's actual capabilities.
Audio context fingerprint
AudioContext processing leaves traces that genuine Chromium can't match when the signature is overridden at the JS layer.
Font availability vs OS
Antidetect profiles often claim fonts the spoofed OS doesn't ship with, or skip OS-default fonts.
JA3 / TLS fingerprint
A session claiming Chrome 118 on Windows but with a Firefox JA3 is mathematically impossible. Diagnostic.
Behavioural timing
Inter-request timings cluster suspiciously when the same antidetect runtime drives many sessions.

Combined with the residential-proxy or VPN flag — antidetect browsers are almost never used on residential IPs without a proxy — Sentinel's antidetectBrowser + browserTampering signals catch >95% of fraud-context antidetect sessions in our testing, with sub-0.1% false-positive rate on real consumer traffic.
