About UFOZoo

UFOZoo is a hardware testing suite that runs entirely in the browser. Dead pixels, stick drift, keyboard chatter, microphone noise, refresh rate, polling rate: open a page and run the test, with nothing to install.

The test benches cover the common input, display, output and sensor devices, alongside benchmark charts for CPUs, GPUs and mobile SoCs. Everything runs on the page itself, and nothing is uploaded.

The site is under continuous development. New tests are published regularly, and reported faults are fixed as they are confirmed.

UFOZoo's tools are grouped by the device they test:

• Benchmarks and specs: CPU, GPU, Apple silicon, server CPU and mobile SoC performance charts, plus a device information reader.
• Input devices: keyboard rollover and chatter, mouse double-click, scroll, polling rate and CPS, gamepad buttons and axes, stick drift, and reaction time.
• Displays: refresh rate, dead pixel, stuck pixel, screen colour and PPI checks.
• Output devices: speaker channel and frequency sweeps, microphone level and noise, webcam preview, and printer test pages.
• Phone sensors: touch screen, vibration, compass and gyroscope checks.

Every test runs in the browser. A dead pixel check draws the test pattern on your screen; a mouse test reads input through Pointer Events; a microphone check analyzes the signal with the Web Audio API. No server is involved, and no software needs to be installed.

The consequence is that whatever a test observes, whether microphone audio, camera frames or keystrokes, stays on your own device. No server processes it, no database stores it, and no third party is asked for permission. The browser sandbox is the only boundary your data crosses.

The site is built with Astro and delivered as static pages through Cloudflare's edge network, so pages load without a backend round-trip.

The hardware tests use the browser's native Web APIs (Gamepad, Keyboard, MediaDevices, AudioContext), the same interfaces games and video tools depend on. Results reflect what the browser can observe on your device; they are diagnostic aids rather than calibrated laboratory measurements.

Because the tools run in the browser, there is no stage at which input could be collected: it exists in memory and is discarded when the tab is closed. The site has no accounts and builds no analytics profiles tied to individuals. Some pages display ads served by Google AdSense to fund the site; see the Privacy Policy for details.

The only infrastructure involved is Cloudflare's CDN, which delivers the static files and handles standard request logging. See the Privacy Policy for details.

Players should know whether their equipment has a fault before a ranked match, not afterwards. The hardware tests are open to anyone with a browser, on any device and in any region, at no cost.

The long-term goal is a complete hardware testing laboratory covering the common input, display, and output devices. New tools are added based on visitor feedback and on what people are actually searching for.

UFOZoo was founded by a web developer with more than a decade of experience in browser-side development, browser-based hardware testing, and performance optimization.
