Fps Test

Realtime Browser Benchmark

FPS Test Tool

Measure your browser’s real rendering performance with a live animation stress test, frame-time tracking, percentile lows, stability scoring, and dropped-frame estimates. It runs directly in the browser with no extra plugins.

Glow trails
Adds visual persistence for a more intense render workload. Reactive background grid
Draws extra motion layers behind the particles. Canvas effects mode
Adds blur, rings, gradients, and extra compositing work.

Run the test with your browser tab visible and your device plugged in for more consistent results. Background tabs can pause animation timing and lower accuracy.

Min / Max FPS

0 / 0

Best and worst instantaneous frame-rate readings.

Stability Score

0%

Higher means smoother frame-time consistency.

Median FPS

0

The midpoint frame-rate result, less affected by spikes.

95th Percentile Frame Time

0 ms

Shows near-worst latency without using the biggest outliers.

Dropped Frame Estimate

0

Approximation based on the chosen or detected refresh rate.

Refresh Match

Unknown

Closest common display refresh rate pattern detected.

Frame Rate History

The graph updates after each test and plots sampled FPS values over time.
