PC Health Check
one click, full report
CPU, GPU, RAM, storage, display, network, battery, codecs and 20+ browser capabilities — measured locally in your browser. Nothing is uploaded.
What this checks
🧠 Compute & graphics
Single- and multi-core CPU throughput (real ops/sec via Web Workers), your GPU model via WebGL's unmasked renderer, WebGL2/WebGPU support and a short render stress sample for sustained FPS.
💾 Memory & storage
RAM estimate, JS heap, a memory-bandwidth micro-benchmark, plus storage quota and how much your browser cache/data is using (the "cache check").
🖥️ Display & network
Resolution, pixel ratio, measured refresh rate, colour gamut/HDR, connection type, downlink, and a live latency ping. Battery level and charging state where supported.
