Technical explanation
The checker tests for API presence and, where safe, creates a minimal object or worker to confirm usability. It deliberately avoids triggering permission prompts.
API presence is not proof of hardware quality. A browser can expose a capability that is disabled by policy, missing a physical device, or limited by the current secure-context state.
Troubleshooting
A supported device shows missing features
Check the browser version, secure-context status, and enterprise policies.
Media features look unavailable
Media APIs may require HTTPS and user permission before a device is exposed.
Storage quota looks low
Private browsing and storage pressure can reduce the reported quota.
Results differ between browsers
Browsers implement different subsets of web APIs.
