Commercial anti-detect browsers fail the same way.
Custom engine overview: commercial anti-detect browsers fail the same way, shared fingerprint, private Chromium from source.
Method first: we tested Dolphin, AdsPower, Octo, and Multilogin on Windows, macOS, and Linux hosts, all OS profiles, headed and headless. Every finding is checked against genuine Chrome on the same OS, and real fullscreen is excluded first.
Dolphin ships the same voice list in the same order, every profile. AdsPower runs a Gecko engine wearing a Chrome identity. Octo patches one font metric and misses the next. Multilogin exposes a pasteAsHuman check that real Chrome fails. Headless builds its window frame in code, so the geometry gives it away.
These are not user agent strings. They are contradictions inside the engine, and they are the same on every copy of the tool. When thousands of teams share one build, one abused account poisons the fingerprint for everyone.
That is why we wrote this blog. Teams burn aged accounts, buy new proxy pools, and switch subscriptions, while the real fault sits in the binary they rented.
Programming Kings builds Chromium from source. Your engine is private to your team, the leaks are fixed in C++, and no vendor can buy your build to write rules against it.
