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.

Browser probe

User-agent probe supplied by the surface.

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

Browser family

Identified browser family.

Browser version

Browser major version digits when detected.

Engine

Rendering engine behind the browser.

Operating system

Operating system name from the user agent.

OS version

Operating system version from the user agent.

Device type

Best-effort device class for the session.

• 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.

• Device Info Checker

  Normalize and classify a device descriptor probe into tiers, form factor, and identification confidence.

• GPU Info Checker

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

• What Is My IP Address?

  Show the public IPv4 and IPv6 addresses available to the current internet connection, reporting either family as unavailable when its probe cannot connect.
