Fingerprint Uniqueness

Playwright and Puppeteer expose identical device fingerprints — they leak the real machine. Owl Browser generates unique fingerprints per profile at the C++ source level.

Identical hash — real device leaked
Unique hash — properly spoofed

Stealth Has a Cost. Here's How Small It Is.

Playwright and Puppeteer run bare — no fingerprint spoofing, no context isolation, no anti-detection. Every Owl request includes all of that, yet full-cycle times stay competitive. 1000 sequential iterations per browser, same machine, same network. Median times shown.

Methodology: Each browser performs 1000 sequential iterations of: create/launch → navigate to target URL (wait for domcontentloaded) → capture screenshot → close. All times in milliseconds. Playwright and Puppeteer run inside the benchmark container (local process). Owl Browser runs in a separate container and is accessed via REST API over localhost, adding ~5-10ms of network overhead per API call — Owl's real times are faster than shown. Sequential execution, same machine. Owl times include the full cost of stealth — fingerprint generation, per-context isolation, and REST API overhead to an isolated container.

Concurrency Scaling

All sessions launch simultaneously. Each performs a full cycle — create context, navigate, screenshot, and close.

Owl, Playwright, and Puppeteer all completed successfully across every concurrency level.

Detection Immunity, Production Speed

Zero headless detection. Unique fingerprints on every session. Competitive full-cycle performance. Deploy Owl Browser and stop getting blocked.
