Stealth mode: browsers that look human

Fingerprints, header hygiene, and human-like timing, on by default so your browsers blend in.

The fastest way to get blocked is to look like a headless bot. Stealth mode ships managed fingerprints, clean headers, and human-like input timing so a Ferr browser reads like a real visitor.

What stealth handles

  • Consistent, managed browser fingerprints
  • Header ordering and hygiene that match real Chrome
  • Human-like mouse and keyboard timing
  • Automatic handling of common challenge flows

One flag

Turning it on is a single argument on session creation. Everything else — the fingerprint, the timing, the headers — is managed for you and updated as detection evolves.
