IT Toolbox

System & network info

Everything IT needs to know about this computer's browser environment.

Screen recorder

Records your screen or a window. The video is saved as WebM (plays in Chrome, Edge and VLC). Nothing is uploaded.

Internet speed test

Uses Cloudflare's global speed-test servers. Takes about 20 seconds — avoid downloading files during the test.

Ping / latency checker

Sends 5 requests to each address and measures the response time. One address per line.

DNS lookup

Queries Cloudflare's DNS-over-HTTPS resolver (1.1.1.1).

Connection monitor

Keep this open to log every internet drop with an exact timestamp. A heartbeat request runs every 10 seconds to catch silent drops.

Keyboard tester

Click below first, then press any key. Green = works. Keys you have already tested stay outlined.

Mouse tester

Click, double-click and scroll inside the test area. Buttons light up while held.

Dead pixel / screen test

Pick a color to go full-screen. Click anywhere to cycle to the next color, press Esc to exit. Look closely for stuck dots or uneven lighting.

Audio recorder

Records from your microphone. Nothing is uploaded — the file stays on this computer.

Battery info

Live battery status (laptops and tablets). Updates automatically when you plug or unplug.

GPU / graphics info

Windows Fix Center

Standard Microsoft repair commands — copy one into Command Prompt / PowerShell, or tick several and download them as one fix script. Commands marked Admin need “Run as administrator”.

Encrypt / decrypt (AES-256)

Real AES-256-GCM encryption with a password (PBKDF2, 310,000 rounds). Everything happens on this computer — nothing is sent anywhere. If the password is lost, the data cannot be recovered.

Bug report builder

Fill in the problem — system details are collected automatically. The result is one HTML file you can send to IT.
