Proof
Measured, not promised.
Antidetect marketing is full of adjectives. This page is the opposite: what we measured, when, on which machines, and the one thing that is still different.
Method
How a claim earns a place on the home page.
A page, not a config
Every value we quote was read by a web page inside the running browser, never from the settings we sent it. If a value is carried but not applied, the page shows the host and the test fails.
Two different Macs
Measurements run on an M5 MacBook and an M4 Pro Mac mini on different macOS versions. Anything that only matches on one machine is not called a match.
Negative controls
We check that the test can fail: a changed byte must be refused, a wrong operating system must be refused, and a report from another run must be rejected.
Receipts
What was measured.
21 September 2026
21 of 21 device values reach the page
On a ten-core M5 MacBook, a profile assigned an iMac 24 (M3) reported 8 cores, 16 GB, a 2240×1260 screen at 2× and an Apple M3 GPU. In the page, in a worker, and in CSS media queries.
15 September 2026
Rendering matches real Chrome
Canvas fills, geometry, the WebGL image and the audio fingerprint hashed identically to stock Chrome, and identically across two different Macs.
15 September 2026
Profiles survive the move
A profile closed on one Mac and opened on another kept its 18 databases and 74 rows intact, under its own per-profile key, with no OS keychain involved.
15 September 2026
One changed byte is refused
A single byte appended inside the engine tree made the next launch fail closed. Integrity is checked, not assumed.
16 September 2026
The device reaches every context
Thirteen device values answered from the signed policy in the main frame, in a dedicated worker and in a cross-origin iframe, and CSS media features agreed with script.
17 September 2026
Media devices follow the device
A profile presenting a laptop listed a built-in microphone and speakers in Chrome's exact shape, five rows for three devices, on a Mac mini that has neither.
17 September 2026
The clock follows the proxy
A profile routed through a proxy whose exit resolved to Vancouver reported America/Vancouver, with its language untouched.
15 September 2026
One build, any Mac
A single provisioned runtime started on both machines and told a page the same macOS version on each, one that neither machine runs.
The residual
One thing still differs between Macs, and it should.
Text rendering. Apple changes its text rasterizer and system font between macOS point releases, so drawn text on a Mac running 26.3 differs slightly from one running 26.6. Real Macs differ from each other in exactly this way; both results are genuine Chrome output, and no site can call either one fake. Everything else a page can render (fills, geometry, WebGL, audio) is identical across our two machines. Keeping a team's Macs on one macOS version removes even this.
