WebGPUStress

WebGPUStress is a free browser-based graphics testing platform for developers, gamers, and PC enthusiasts. Instead of installing a traditional desktop benchmarking application, users can run configurable GPU workloads directly in a supported web browser. The main GPU stress test uses WebGL rendering and provides measurements such as: Average FPS 1% Low FPS Frame-time stability Dropped-frame ratio Stability score Performance trends during sustained testing Users can choose test duration, rendering resolution, graphics quality, and target FPS. The application also provides separate tools for WebGPU compatibility, GPU detection, shader testing, WebGL support, and browser frame-rate measurements. Completed benchmark reports can be saved locally and compared with previous results. The focus is on accessible and repeatable graphics performance testing. Browser-based results are influenced by drivers, refresh rates, power settings, and browser scheduling. The platform does not claim to diagnose GPU hardware defects or directly measure temperature.
