Use this check to inspect a browser, device, network, permission, media, or input capability directly in the current runtime before relying on it in another workflow.

Device probe

Device descriptor probe supplied by the surface.

Normalize and classify a device descriptor probe into tiers, form factor, and identification confidence. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Architecture

Canonicalized architecture identifier.

CPU tier

Logical core count classification.

Form factor

Resolved physical device class.

Memory tier

Memory size classification.

Confidence

How completely the probe identifies the device.

Operating system

Normalized operating system name.

Missing fields

Absent core identification fields.

OS version

Trimmed operating system version.

• Results describe the current browser session and can change with permissions, privacy controls, hardware, drivers, network path, power state, or browser updates. Unsupported or withheld information is not proof that the underlying capability is absent.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Repeat the check in the browser and device that will actually be used, then confirm important behavior with the relevant operating-system or network diagnostics. Avoid granting permissions that are unnecessary for the test.

• Browser Info Checker

  Parse a user-agent probe into browser family, engine, operating system, and device type.

• GPU Info Checker

  Classify a GPU probe into vendor, model token, and integrated versus discrete hints.

• Audio Output Tester

  Diagnose audio playback from an output probe covering rate, channels, latency, and underruns.
