Evasion
Stealthium is a custom Chromium fork with evasion engineered inside the browser stack, not bolted on with scripts. For environments where failure is not acceptable.
The Problem
Accumulates
Anti-bot vendors operate with billions in funding, privileged visibility across the web, and continuous model-driven detection. The web platform keeps expanding: new APIs, new entropy surfaces, new telemetry.
Script Detection
Basic automation property checks. Easily patched.
Behavioral Fingerprinting
Multi-surface correlation, timing analysis, ML classifiers.
Engine-Level Telemetry
V8 semantics, renderer coherence, protocol artifacts.
Solve It Where
Signals Generate
Stealthium implements evasion inside Chromium and V8, where feature exposure, execution semantics, and rendering behavior originate. Not simulated. Enforced.
Patching Cannot Reach Deep Signals
JavaScript patches sit above the engine. They cannot control V8 timing, renderer micro-differences, or protocol artifacts. Every patch creates new surface for correlation.
CDP and Control Planes Leak
Automation frameworks control browsers through protocols never designed for stealth. Command patterns, timing signatures, and state changes become detectable at scale.
Coherence Enforced at Origin
Stealthium modifies Chromium and V8 directly. Fingerprinting control, behavioral consistency, and artifact elimination happen where signals are generated, not where they are observed.
Why Most
Solutions Fail
Chromium is one of the largest codebases on earth. Effective evasion requires preserving coherence across a shifting set of signals, without breaking real site functionality.
Fingerprinting Is Multi-Surface
Modern detection combines engine-level behavior, rendering surfaces, API consistency, protocol artifacts, and cross-session correlation. Patching one surface leaves dozens exposed.
Chromium Moves Fast
Every upstream change can introduce new observable behavior. "Stale" builds stand out. Maintaining parity with Chrome's release train is baseline hygiene for operating under scrutiny.
Maintenance Is The Product
Stealthium is built as a long-term engineering program. Continuous updates, upstream parity, security posture maintenance, and new evasion capabilities as the ecosystem shifts. This is not a feature, it's the foundation.
Containerized.
Private.
Stealthium ships as a Docker container you deploy in your own environment. No hosted browser infrastructure. No sensitive data leaving your perimeter. Compatible with strict compliance and internal security requirements.
Self-Hosted Runtime
Deploy on-premise, private cloud, or air-gapped networks.
Compliance Ready
SOC 2, GDPR, and regulated environment compatible.
CI/CD Integration
Seamless integration with existing pipelines and orchestration.
