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.

Represents the slowest 1% of frame-rate moments.
Min / Max FPS
0 / 0
Best and worst instantaneous frame-rate readings.
Stability Score
0%
Higher means smoother frame-time consistency.
Median FPS
0

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
