Browser Speed Test — Performance Benchmark

One-click composite benchmark of your browser's JavaScript engine, DOM speed, CSS rendering and animation frame rate.

⚙️ JS Engine Score

Measures raw JavaScript compute speed — floating point math and loops. Faster CPUs and better JIT compilers score higher. V8 (Chrome/Edge) typically leads.

🌐 DOM Score

Tests how fast the browser can create, modify, and remove DOM nodes. Critical for web apps with lots of dynamic content. Chrome and Firefox are typically tied.

🎞️ FPS (requestAnimationFrame)

Measures how many animation frames per second your browser and GPU can sustain. 60fps is the standard display refresh rate. Above 60 indicates a high-refresh display.

🎨 CSS Rendering Score

Tests canvas 2D drawing speed — a proxy for GPU-accelerated rendering. Affected by your GPU, browser's compositor, and display resolution.
