01

Useful immediately

Every tool is built around a single job: open the page, perform one action and get a useful answer without registration or setup.

02

Private by design

Camera, microphone and input tests use browser capabilities directly. Media streams and test activity are not uploaded by the diagnostic tools.

03

Honest about limits

A browser test cannot replace hardware laboratory equipment. Each page explains what it can confirm and what may still require system settings or professional support.

The principle

Good diagnostics reduce uncertainty.

We focus on clear feedback, accessible controls and transparent measurements. Advertising, when present, is visually separated from the tests so the useful part of the page remains the reason to visit.
