What is WebGPUStress?
A privacy-first, zero-install web tool that pushes your graphics card using WebGL/WebGPU shaders. It runs entirely in the browser and shows live FPS, frame time, drop ratios, and a stability score so you can spot thermal throttling, VRAM problems, or unstable overclocks. Ideal for laptop thermal checks, new PC validation, VM sanity checks, and troubleshooting gaming stutter. It does not read GPU temperatures (use MSI Afterburner or GPU-Z for temps). Keep the tab focused for accurate results and stop the test if you see visual artifacts.
Key features
- Run GPU stress tests directly in your browser without installing.
- Uses WebGL/WebGPU shaders to saturate GPU cores and VRAM.
- Live FPS, frame-time, and stability score shown in real time.
- Detects performance drops indicative of thermal throttling or instability.
- No large downloads and runs within the browser security sandbox.
- Compatible with Chrome, Edge, Firefox, and Safari across platforms.
