Stealth modes

Choose how aggressively a launch shapes its fingerprint. The mode is set per launch and ranges from clean Chromium to the strongest noise.

Modes

Pass stealth in the launch body. The default is balanced.

Mode	Behavior
off	Clean Chromium with no fingerprint injection. Chrome engine only.
balanced	Native fingerprints. The default for most launches.
max	The strongest noise applied to the fingerprint surface.

off is useful when you want a plain browser with no spoofing, for example for internal testing.
off is Chrome only. Firefox engine profiles always spoof their fingerprint regardless of the requested mode.
balanced aims to present coherent, native looking values rather than obvious noise.
max favors stronger randomization where it does not break coherence.
