Diagnose Your VR Headset Online

Free diagnostic suite for VR headset owners that runs entirely in the headset browser through WebXR. Opens a Three.js scene with FOV reference markers, a tracking target and refresh-rate sampling; the page also serves 2D fallback tests — fullscreen color cycling for dead pixel inspection and an HRTF-panned spatial audio loop for stereo check — that work in any browser.

How to test a VR headset online

1
Put on your headset

Launch Meta Quest Browser, Wolvic, Vision Pro Safari or Pico Browser — any modern WebXR-capable browser.

2
Open this page inside the headset

Scan the QR code from this page on your desktop, or type the URL directly in your headset browser.

3
Press "Enter VR"

An immersive Three.js scene loads with 15° FOV markers, a rotating tracking target and a floor grid.

4
Look around the markers

Yellow markers are placed every 45°, blue every 15°. Turn your head — how many can you see without moving the eyes?

5
Exit and read results

Back on the 2D page, refresh rate and frame-time statistics appear. Compare with your headset's advertised 72/90/120 Hz.

In-headset diagnostics via WebXR

Open this page inside your VR headset browser (Meta Quest Browser, Wolvic, Vision Pro Safari, Pico Browser) and enter an immersive scene that stress-tests FOV coverage, tracking smoothness, refresh rate and spatial audio. Fallback 2D tests run in any browser.

Frequently asked questions

Why must I open this in the headset browser?

WebXR sessions require a user gesture inside a browser that the headset controls. Opening the page on a desktop only lets you run the fallback 2D tests — full FOV, tracking and refresh rate measurements need the immersive session.

Which browsers support WebXR immersive-vr?

Meta Quest Browser, Wolvic (Quest, Pico, Lynx), Pico Browser, Vision Pro Safari, plus Chrome/Edge with a tethered Quest via Oculus Link. Firefox Reality is deprecated — use Wolvic instead.

Can you detect FOV exactly?

We place reference markers at known angles, but the human report is subjective — the test tells you "can you still see the 105° marker?" not "your FOV is X degrees". WebXR does expose the projection matrix, which we use to compute the headset's logical FOV approximately.

Does this work on Vision Pro?

Partially. Vision Pro Safari supports WebXR since visionOS 2, but immersive-vr is more limited than on Quest. Passthrough AR works best. Hand tracking is exposed to WebXR.

How do I check my PC's VR compatibility?

Use the dedicated VR compatibility test which checks GPU, CPU, RAM and bandwidth for PCVR and streaming.

I have not bought a headset yet — where do I start?

Try our VR readiness test first — it measures your IPD, stereo vision and motion sickness risk so you buy a headset that fits you.
