Simple, Accurate & 100% Browser-Based Hardware Diagnostics
Our platform was built with a clear purpose: eliminate friction in diagnosing computer peripherals and components for millions of users, technicians, gamers, and professionals worldwide.
Our Mission
To provide the most comprehensive, accessible, and privacy-friendly hardware testing suite online. We believe anyone should be able to diagnose issues with their laptop or desktop in seconds — with no suspicious executable downloads, no registration walls, and no intrusive ads.
We support diverse international keyboard standards including ANSI (US), ISO (Europe), ABNT2, and Apple macOS layouts, alongside high-precision audio and display test routines.
Why We Built This Platform
Buying a refurbished laptop, assembling a gaming rig, or troubleshooting faulty peripherals used to require tedious manual tests or shady bloatware applications.
We created this suite to unify keyboard, mouse, audio, display, and port diagnostics into a single clean, ultra-responsive, and modern web interface inspired by world-class design standards.
Who Benefits from Our Tools?
Our suite is engineered to serve everyday users as well as professional IT repair specialists and competitive gamers.
Gamers & eSports Enthusiasts
Verify genuine NKRO anti-ghosting, test click speed (CPS), and analyze polling rate (Hz) and switch chatter before jumping into competitive matches.
IT Technicians & Repair Shops
Speed up bench repairs. Test laptop keyboards after part replacement or liquid damage cleanup without installing heavy diagnostic software on client machines.
Used Laptop Buyers & Sellers
Buying or selling pre-owned hardware on eBay or marketplace? Run a complete check on all keys, stereo speakers, and screen dead pixels in under 2 minutes.
Remote Workers & Students
Ensure your headset, microphone, monitor, and keyboard are functioning flawlessly before important meetings or online exams.
How the Technology Under the Hood Works
Our tools are engineered using modern, low-level browser Web APIs to deliver maximum precision with zero server processing:
Low-Level Keyboard Event API
We capture physical key codes (event.code) directly, allowing accurate diagnosis of physical hardware defects versus operating system language layout mapping issues.
High-Fidelity Web Audio API
Utilizing hardware-level oscillators and stereo pan nodes to generate pure sine waves (20 Hz to 20,000 Hz) and verify absolute left/right channel acoustic isolation.
Pointer Events & Gamepad / WebUSB API
High-frequency event listeners calculate real mouse polling rates in Hertz (Hz), detect multi-button inputs, and inspect connected physical peripherals.
Our Core Pillars
Total Privacy
100% of testing logic runs locally in your browser. No keystrokes, clicks, or audio inputs are ever recorded or transmitted to servers.
Blazing Speed
Zero bloat and modern architecture ensure instant loading times and sub-millisecond interaction feedback.
Universal Compatibility
Works seamlessly across Windows, macOS, Linux, and ChromeOS across ANSI, ISO, and regional keyboard layouts.
100% Free Forever
Open and unrestricted access for everyone. Free to use with no hidden subscriptions or forced paywalls.
