PC Diagnostics Report

Generate a shareable, browser-based PC diagnostics report: GPU, CPU, RAM, display, storage and platform summary with an honest self-check — all locally, nothing uploaded.

What this checks

Click "Run diagnostics" to detect what your browser can honestly see: your GPU renderer (via WebGL), CPU core count plus a quick single-thread compute probe, RAM (where the browser exposes it), display resolution and refresh rate, a storage estimate, and your OS/browser. Each signal gets an honest verdict — in range, below expected, or can't tell. Everything runs in your browser; nothing is uploaded and there is no sign-up.

When to use PC Diagnostics Report

Common reasons to generate a shareable hardware summary:

  • Generate the diagnostics report

    Click "Run diagnostics" and get a combined GPU/CPU/RAM/display/storage/platform report with an honest self-check within seconds.

  • Read an honest self-check

    See at a glance which signals look healthy and which are below the expected range for your device class — with browser limitations stated honestly.

  • Copy a neutral, shareable summary

    Copy a clean, factual text summary to your clipboard and paste it into a forum thread without a biased score.

  • Share via QR code or download JSON

    Scan a QR code on a device without a keyboard, or hand a machine-readable JSON file to a helper.

  • Re-run and stop on demand

    Re-check after a hardware or driver change, or stop a run that is taking longer than expected and return to a clean idle state.

Frequently Asked Questions

What does this PC diagnostics report show?
It detects what your browser can honestly see: your GPU renderer (via WebGL), CPU core count plus a quick single-thread compute probe, RAM (where the browser exposes it), display resolution and refresh rate, a storage estimate, and your OS/browser. Each signal gets an honest verdict — in range, below expected, or can't tell.
Is my data uploaded anywhere?
No. Everything runs in your browser. The report, QR code, and JSON file are all produced on your device and never sent to a server. There is no sign-up and no account.
Why does some information say "can't tell"?
Browsers deliberately hide or approximate some hardware details for privacy. For example, RAM is often capped at 8 GB and GPU temps/clocks are never exposed to web pages. When a value isn't available we say "can't tell" and explain why, instead of guessing.
How accurate is the CPU measurement?
The CPU figure is a quick single-thread JavaScript compute probe — a rough proxy for processing speed, not a full multi-core benchmark. It's meant to give context for a shareable summary, not to rank your CPU. The report says this plainly.
Can I share the report?
Yes. Copy a neutral text summary to your clipboard, scan a QR code, or download a JSON file. The summary is factual and states every browser limitation, so it reads as a neutral hardware overview rather than a biased score.
