Stealth Browser Engine

Browser sessions that
websites can't fingerprint.

Every session gets a unique fingerprint, residential IP, and human behavioral patterns. Drop-in replacement for Playwright.

Session spin-up
256-bit
Vault encryption

Built on quantitative behavioral modeling.

Unique Fingerprints

Canvas, WebGL, audio, and navigator fingerprints — entropy-optimized to sit in the statistical middle.

Behavioral Engine

Hawkes process modeling for mouse, click, and scroll patterns. Statistically indistinguishable from humans.

Identity Vault

Agents log in once, sessions remember auth. AES-256-GCM encrypted with zero-knowledge architecture.

HMM Evasion

Real-time regime detection. When a site probes for bots, the browser adapts automatically.

Residential Proxies

Every session gets a unique residential IP. No datacenter detection signals.

Drop-in SDK

Three lines of Python. Same CDP interface as Playwright. Zero learning curve.

Usage-based. Per session-minute.
