Anti-Detect & Browser Automation Glossary

Anti-detect browser: Software that runs isolated browser profiles, each with distinct fingerprints, cookies, and storage — used for multi-account workflows without cross-session linkage.
Multilogin: Commercial anti-detect platform with API-driven profile launches, team workspaces, and automation integration. See setup guide and promo codes.
CDP (Chrome DevTools Protocol): WebSocket protocol to control Chromium. Playwright connectOverCDP and Selenium debugger attach use CDP to drive anti-detect profiles.
Browser fingerprint: Unique-ish identifier built from Canvas rendering, WebGL parameters, installed fonts, screen size, timezone, language, and audio context — used by anti-bot systems.
Canvas fingerprint: Hash of how browser renders hidden canvas elements. Inconsistent hashes across sessions in the same profile indicate spoofing instability.
WebDriver leak: Presence of navigator.webdriver === true or related CDP artifacts signaling automated control.
Headless detection: Bot systems flag headless Chrome via missing plugins, non-standard user agents, and WebGL renderer strings.
Proxy geo alignment: Matching IP geolocation with browser timezone, language, and geolocation API — critical for avoiding instant blocks.
GeeLark: Cloud phone platform focused on TikTok and social media multi-account workflows. See cloud phone comparison.
DuoPlus: Cloud Android provider common in cross-border e-commerce and TikTok shop operations.
VMOS Cloud Phone: Cloud-hosted Android environment; validate app attestation pass rate per use case.
AdsPower: Anti-detect browser with high profile counts and local API — compared in best anti-detect 2026.
GoLogin: Anti-detect browser using Orbita Chromium — entry-tier pricing, lighter team features.
Dolphin Anty: Anti-detect browser popular in affiliate and media-buying workflows.
TLS fingerprint (JA3/JA4): Hash of TLS handshake parameters — CDNs use it independently of JavaScript Canvas. See fingerprint deep dive.
User-Agent Client Hints: HTTP headers (Sec-CH-UA*) that expose real platform/architecture — must align with spoofed User-Agent.
Device attestation: Mobile integrity checks (Play Integrity, SafetyNet) — why cloud phones differ from desktop anti-detect.
Meta Business Manager: Web dashboard for Facebook/Instagram ads and pages — run each client on an isolated anti-detect profile.
Shopee seller: SEA marketplace — one Multilogin profile per country (VN, PH, MY, SG, TH, ID). Guides: PH/MY, SG/TH. Mobile app typically needs cloud phone with matching country IP.
Cloud phone: Remote Android/iOS device for mobile app automation. Different threat model from desktop anti-detect browsers — see cloud phone hub and TikTok guide.
PerimeterX / HUMAN: Behavioral bot mitigation — press-and-hold challenges, mouse scoring. Requires human-like interaction patterns, not just fingerprint spoofing.
Cloudflare challenge: TLS fingerprinting, JS challenge, and turnstile captcha layers. Triage IP reputation and TLS stack before tuning browser flags.
Profile warm-up: Organic browsing (scroll, idle, navigation) before high-value actions to build behavioral trust scores.
Health probe: Scheduled check that starts a Multilogin profile headless, pings CDP WebSocket, then stops — no platform login. Three fails in 24h triggers tier demotion. Implemented in profile pool and scheduled via health check cron. Alerts: Grafana health probe alerts.
Warm tier: Redis set mlx:pool:warm — profiles warming cookie/trust scores or recovering from soft failures. Promote to prod only after health probe pass and cooldown. See profile pool manager.
CMDB burn tier: Profile classification after ban or linkage suspicion — moved from mlx:pool:prod to mlx:pool:burn. Never auto-delete; clone for forensics first. See ban recovery and profile pool.
Profile lease: Redis SET NX lock on mlx:lease:{profile_id} with TTL — prevents duplicate CDP launches from parallel workers. Core pattern in queue worker.
Dead letter queue (DLQ): Redis list mlx:dlq holding jobs that exceeded max_attempts. Handled by DLQ handler — classify, alert, replay.
Sticky ISP proxy: ISP or datacenter proxy with stable exit IP for days/weeks — required for Amazon, Walmart, Allegro seller panels. Contrast with rotating residential. See sticky vs rotate.
Cross-listing CMDB: Configuration record linking marketplace profiles by client_id without sharing cookies. SEA: SEA CMDB. US: US CMDB. EU: EU CMDB.
Tokopedia seller: Indonesia marketplace — separate Multilogin profile from Lazada ID and Shopee ID. EN: Tokopedia guide. VI: Tokopedia (VI). ID: Tokopedia (ID).
Temu / Shein seller: Cross-border marketplace sellers — hybrid ops with Multilogin web + cloud phone mobile. See Temu & Shein guide.
