Browser and device diagnostics

Capture a local browser diagnostics report: screen, viewport, languages and available web features. Filter the list and export a fixed snapshot.

These diagnostics are read in this browser only after you press the button. The tool makes no diagnostic API request, does not request camera or location access and does not save its report in browser storage.

Browser data is not a full hardware specification. User-Agent may be reduced or spoofed, memory is approximate, logical cores may be restricted and “online” does not prove internet access. A reported web feature may still require permission or a secure page.

View device information online

View detailed browser, screen, viewport and device capability information reported by your current device.

Useful for responsive testing, support diagnostics, user environment reports and browser troubleshooting across phones, tablets and desktops.

Quick start

Capture browser diagnostics locally without permission requests or automatic refresh.

  1. Read the privacy and hardware limitations
  2. Capture a fixed diagnostics snapshot
  3. Filter the list and export the full report
✓ The tool runs directly in the browser and is ready for quick checks without installing software.
✓ Input can be cleared and recalculated immediately, which is useful for repeated small tasks.
✓ Use fullscreen mode when you need more space for long text, structured data or large result blocks.
✓ Copy buttons are available on generated output so results can be reused in code, documents or support chats.
✓ Most operations are deterministic: the same input and options produce the same output.
✓ For sensitive content, prefer local browser tools and review the result before sharing it further.
