The Sendwin Stealth Engine explained
Sendwin's patched-Chromium engine spoofs canvas, WebGL, audio, fonts, hardware and more together so each profile looks like a real device.
The Sendwin Stealth Engine is a patched build of Chromium that powers every desktop profile. Instead of just changing your User-Agent string, it spoofs your device identity at the engine level, so the values a website reads are internally consistent and look like a genuine, distinct computer.
The key idea is that all of a device's signals are spoofed together. If only one value changed, sites could spot the mismatch. The engine keeps everything coherent per profile.
What the engine spoofs
- Canvas rendering
- WebGL
- Audio
- Installed fonts
- Hardware characteristics
- Timezone
- User-Agent client hints
Because these are handled at the engine level rather than by simple JavaScript injection, each profile presents as a separate real device rather than a browser with a few properties patched over.
Chrome or Edge identity
A profile's browser identity can be either Chrome or Edge. This is part of the fingerprint the engine produces, so the brand a site detects matches the rest of the profile's signals.
Tip
The engine runs the same way whether you launch a profile locally on the desktop app or run it in the cloud, so a synced profile keeps its fingerprint no matter where it runs.
