HTML5 Fish Bowl Benchmark is an online browser graphics performance tool. It continuously draws swimming fish inside a fish-bowl scene and combines water, masks, highlights, and shadows so you can quickly see how smooth Canvas animation feels on your current device and browser.

The idea follows a classic web performance demo: stronger browsers and computers usually sustain higher frame rates and handle more fish at once. Use it to compare browsers, devices, or the same machine before and after enabling hardware acceleration.

Key Features

• Renders an animated fish-bowl scene with Canvas so stuttering and frame drops are easy to notice.
• Lets you switch fish counts with presets, including an Auto mode that adapts to performance.
• Provides layer toggles for water, frame, mask, back, fish, front, shine, shadow, audio, logo, FPS meter, and needle to isolate costly layers.
• Shows FPS-related visual feedback to help you understand frame-rate changes over time.

Who It Is For

• Front-end developers validating Canvas animation quality in target browsers.
• Everyday users comparing smoothness across PCs, tablets, or phones.
• Anyone who wants a quick web-graphics check after installing or upgrading a machine.
• People troubleshooting slow animation caused by extensions, power-saving modes, or heavy background load.

How to Use

1. Open the tool and wait for assets to finish loading; the animation starts automatically.
2. Use the Fish menu to choose a fish count, or select Auto for adaptive pressure.
3. Watch visual smoothness and check the FPS indicators for stability.
4. Toggle Layers items to compare performance with decorative effects turned off.
5. Mute Audio when needed, or hide non-essential layers to focus on fish rendering cost.

How to Read the Results

Higher and more stable frame rates usually mean the browser handles Canvas drawing more comfortably. If increasing fish count causes stutter, frame drops, or louder fans, you are near the current environment's limit. Browser engines, GPU drivers, and hardware acceleration can change results on the same device, so treat the tool as a relative comparison rather than an absolute score.

Tips

• Close other heavy tabs and apps before testing for a cleaner peak result.
• On laptops, plug in power so battery-saving policies do not throttle performance.
• If loading stalls, check network access and whether media assets are available.
• Mobile browsers can run the demo, but high fish counts are better suited to desktop stress tests.

FAQ

Why is it laggy even with few fish?

Hardware acceleration may be off, drivers may be outdated, system resources may be busy, or the tab may be background-throttled. Try another browser or update GPU drivers, then compare again.

Can a very high fish count damage my computer?

It generally will not damage hardware, but CPU/GPU usage and heat can rise quickly. Lower the fish count or close the page if it becomes too hot or noisy.

What does a higher FPS after disabling a layer mean?

That layer was comparatively expensive. Water video, shine effects, and large fish counts often add significant cost when combined.

Can this replace professional benchmark software?

No. It is best for quick web Canvas animation checks and browser comparisons, not as a complete hardware review.
