Fireworks Simulator: Launch Your Own Light Show
This fireworks simulator lets you stage a virtual fireworks display right in your browser. Click or tap anywhere on the screen and a rocket flies up and bursts into colorful particles at that exact spot — no real fireworks, no noise, no setup.
Pick from seven burst patterns and five color palettes, set the scene with a starry sky, city skyline, or aurora, and let auto-shoot fill the sky on its own. When you want a showstopper, run the 30-second grand finale that builds to a sky-wide crescendo. It is made for celebrations, calming ambient backdrops, or simply enjoying fireworks without the smoke.
How to Use the Fireworks Simulator
Click or tap to launch
Click or tap anywhere on the sky to send a firework to that position. Hold down your click or finger to fire rapid bursts around the cursor for a continuous stream of explosions.
Open Settings
Tap the gear icon in the top corner to open the panel, where you choose the Burst Type, Color Palette, and Background scene for your show.
Tune the effect
Adjust the Particles and Gravity sliders, toggle the glowing Trail Effect, and switch the launch and explosion sounds on or off. Auto Shoot is on by default to fill the sky automatically.
Run the grand finale
Press the Finale Show button to start a 30-second spectacular. It begins slow and builds to a breathtaking barrage of fireworks across the entire sky. Press it again to stop early.

Frequently Asked Questions
Is the fireworks simulator free, and do I need to download anything?
It is completely free and runs in your browser — there is nothing to download or install. Open the page and start launching fireworks straight away.
How do I launch fireworks?
Click or tap anywhere on the screen and a rocket flies up and bursts at that position. Hold your click or finger down to fire rapid bursts around the cursor. By default, Auto Shoot also launches fireworks on its own.
Can I change the firework colors and patterns?
Yes. Open Settings to pick from 7 burst types (Classic, Chrysanthemum, Willow, Ring, Star, Heart, or Random) and 5 color palettes (Rainbow, Golden, Neon, Pastel, Patriotic). You can also change the background scene and adjust particles and gravity.
How do I start the grand finale?
Press the play button next to the settings gear, or open the panel and tap the Finale Show button. The show lasts 30 seconds and builds in intensity. Press it again to stop early.
Why is there no sound when fireworks auto-launch?
The launch sound is kept quiet during auto-shoot to avoid repetitive noise. When you click or tap to launch manually, the launch sound always plays. You can also turn it on permanently with the Launch Sound toggle in Settings.
Does it work on mobile and tablets?
Yes, it is fully touch-friendly. Tap to launch fireworks and hold your finger down for rapid-fire bursts. The settings and finale buttons stay visible for easy access on smaller screens.
The animation feels slow — what can I do?
Lower the Particles slider and turn off the Trail Effect to ease the rendering load. Choosing the None background also helps, and the simulator automatically pauses when you switch to another tab.
Are my settings saved, and is any data collected?
Your preferences are saved automatically and restored when you return. Everything stays in your own browser — no data is sent to any server.
