CURRENT PROJECTS [Active Builds]
Website Fingerprint Spoofer
Active / v2.1"When observation becomes tracking, entropy is the only defense."
Advanced privacy utility to spoof and randomize browser fingerprints against persistent web trackers. Intercepts and injects imperceptible noise into Canvas 2D, masks WebGL vendor & renderer strings, perturbs AudioContext oscillator buffers, and camouflages hardware concurrency without breaking site functionality.
StealthScrape Engine
In Development"Real browsers leave fingerprints; automated ones leave signatures. Eradicate the difference."
Resilient web automation framework engineered for challenging, sensor-heavy web environments. Features native V8 prototype patching, CDP artifact eradication, dynamic TLS JA3/JA4 profile rotation, and humanized biometric cursor movement simulation.
"Randomness breaks applications. Deterministic realism stress-tests them."
Deterministic hardware & behavioral matrix generator for automated testing and staging environments. Generates realistic, statistically balanced browser profiles with correlated screen resolutions, color depths, platform tokens, and system fonts to test anti-abuse models.
