About these System tools
System tools report what this browser can see: OS hints, CPU cores, memory pressure, screen, GPU renderer, connection type, media devices, and permission state. They are for debugging "works on my machine" issues and checking what a web app can access.
A website cannot read your full hardware inventory. Values come from browser APIs, which may be spoofed, rounded, or blocked for privacy. Treat them as what the page is allowed to know, not a BIOS dump.

How these tools run in your browser
We call navigator, screen, User-Agent Client Hints when available, navigator.mediaDevices, and the Permissions API. Public IP, if shown, requires a request to an IP echo service from your browser; other fields stay local. GPU info often comes from WebGL unmasked renderer strings when the browser exposes them.
Common Use Cases
- Confirm the browser engine and version a user is actually running
- See if a camera or mic is enumerated before you debug getUserMedia
- Check permission state for notifications or geolocation
- Read approximate connection quality for a support ticket
- Capture screen size and DPR when a layout bug is viewport-specific
Common Mistakes
Frequently Asked Questions
Safari and locked-down browsers omit several fields. That is expected, not a bug in the tool.
We do not store a fingerprint. The same APIs can be used for fingerprinting on other sites. Use a privacy browser if that is a concern.
