Stealth Mode

Cykani's stealth mode makes your browser instances undetectable by bot detection systems.

How It Works

Each browser session gets a unique, consistent fingerprint that includes:

• Canvas fingerprint — Randomized rendering hash
• WebGL fingerprint — Spoofed vendor/renderer strings
• Audio fingerprint — Randomized audio context values
• Navigator properties — webdriver hidden, plugins spoofed
• Timezone/locale — Configurable per session
• Font list — OS-appropriate font enumeration

Stealth Profiles

Default

Balanced stealth with good performance:

import { strike } from "cykani-stealth";
const session = await strike();

Aggressive

Maximum stealth, slightly slower:

const session = await strike({
  fingerprint: 424242, // deterministic seed
  instincts: { hesitation: 0.8, precision: 0.9, curiosity: 0.5 },
});

Custom Fingerprint

Fine-tune individual settings:

const session = await strike({
  fingerprint: 424242,
  platform: "windows",
  locale: "en-US",
  timezone: "America/New_York",
  operate: { latency: "human" },
});

Fingerprint Modes

Detection Evasion

Cykani patches common detection vectors at the C++ level:

Testing Stealth

import { strike } from "cykani-stealth";

const session = await strike({ humor: true });
await session.goto("https://bot.sannysoft.com");
await session.screenshot({ path: "bot-test.png" });
await session.close();

Best Practices

1. Use a proxy — Pass a proxy via the proxy option
2. Match timezone to proxy — Use the timezone option
3. Rotate fingerprints — Omit the seed for random fingerprints
4. Don't change fingerprints mid-session — Creates anomalies
5. Use realistic viewport — viewport: { width: 1920, height: 1080 }
