Free Browser-Based Device Testing

No downloads

Use the tests directly from a compatible web browser.

Privacy focused

Permissions are requested only when a test needs them, and network tools explain when external services are required.

Focused diagnostics

Choose a specific hardware, phone, display, browser or network check instead of installing a large diagnostic package.

How Device Tests Work

Choose a test. Select the hardware, phone, browser or network feature you want to check.
Allow access when required. Camera, microphone, motion or other protected features are requested only when the relevant test needs them.
Interact with the test. Press keys, move controls, speak, play audio, inspect the display or review browser-reported information.
Review the result. Use the result to narrow down whether the issue is related to hardware, browser support, permissions, settings or the current connection.

Privacy-Focused Browser Testing

Most hardware tests process results locally inside your browser. Camera and microphone access begins only after you start the relevant test and approve permission. Network tools that require public-IP or geolocation data contact external services and explain this within the tool.

No software installation required.
Protected browser permissions are requested only when needed.
External network requests are used only where the selected test requires them.

Phone: General phone, iPhone, Android and used-phone checks.
Browser & Network: Permissions, device information, public IP, IPv4, IPv6, ISP and related network information.

Online Tests for Computers, Phones, Displays and Controllers

Device Tests combines focused browser diagnostics instead of putting unrelated checks into one page. That makes it easier to test a specific component, compare browsers or devices, and move between related tools such as Webcam Test, Camera Resolution Test and Webcam FPS Test.

Display tools cover resolution, colour, refresh rate, dead pixels, monitor ghosting and visual response behaviour. Gaming tools cover general gamepads plus controller-specific, deadzone, drift and polling checks. Phone tools provide general, iPhone, Android and second-hand device workflows.

Limits of Browser-Based Diagnostics

A webpage cannot inspect every internal hardware component or replace laboratory equipment. Results show what the current browser can observe or interact with during the session. Browser support, permissions, drivers, operating-system behaviour and hardware capabilities can affect what each test can measure.

Frequently Asked Questions

Are the device tests free?

Yes. The tests are free to use and do not require a software download.

Do I need to install anything?

No. The tools run from compatible browser features already available on the device.

Do the tests work on phones?

Many tests work on compatible phones and tablets. Device Tests also includes dedicated Phone Test, iPhone Test, Android Phone Test and Used Phone Test pages.

Can I check my public IP?

Yes. The What Is My IP page checks public IPv4 and IPv6 connectivity and can show ISP, ASN and approximate IP-based network information when available.

Can a browser test prove hardware is perfect?

No. Browser diagnostics are useful for checking observable behaviour but cannot replace professional hardware inspection or manufacturer diagnostics.

Why do results differ between browsers?

Browsers expose different APIs, permissions and hardware capabilities, so the same device can produce different browser-observed results.
