Everything runs in your browser

TEST

Check your microphone., camera., speakers., keyboard., network., screen.

Ten hardware testers that run entirely in your browser. Nothing is uploaded — measure, then share or download the report.

01PC check

Full desktop sweep.

02Mobile check

Everything a phone should report.

Reads touch support, physical screen size, notch insets, battery, mobile network and haptics — the things that only matter on a phone.

The test pulls real traffic through Cloudflare's speed endpoints, measuring actual throughput rather than estimates. Run it a couple of times — results vary with Wi-Fi load and other apps.

What to look for

  • Polling rate — 125 Hz is standard, 500–1000 Hz is gaming-grade.
  • Double-click — should be well under 500 ms; if it feels sluggish, raise it in your OS mouse settings.
  • Side buttons — press Back/Forward to confirm they register at all.
