What this test measures
The page measures Canvas, WebGL, WebGPU, Audio, Fonts, ClientRects, and TextMetrics: seven browser-exposed rendering or capability surfaces. It does not create an eighth composite fingerprint.
How it works
Deterministic browser-local measurements run twice in the current page. MyLeaks compares each available surface’s two hashes for same-page repeatability. See Methodology for the exact existing measurement inputs and interpretation boundaries.
What stability means
Stable means that two measurements matched during this page load. Unstable means that the repeated measurements differed.
Limitations
- Browser, operating-system, fonts, graphics and audio implementations, virtualization, and privacy controls may affect exposed values.
- Browser-reported GPU information may not match the exact physical hardware.
- WebGPU may be unsupported or unavailable in some browsers.
- Many browsers can share the same surface values.
