Peony, ring, willow, heart, palm and crackle bursts, each with its own physics for natural, imperfect beauty.

🎨

Switch between rainbow, festive gold, cool and warm palettes, or let every shell pick a random color.

Turn on auto play for an ambient show, or hit Finale for a dense barrage of celebratory bursts.

Synthesized launch whistle and boom via Web Audio — toggle it on for extra atmosphere, off by default.

Full touch support with multi-touch launches, adaptive particle density and smooth 60fps rendering.

The full-screen night sky loads instantly — no sign-up or download required.

Click or touch anywhere and watch a firework rise and burst with a random shape and color.

Open settings to pick a specific shape, palette, particle density and auto-play rate.

Is this fireworks simulator free?

Yes. It runs entirely in your browser at no cost, with no account, download or watermark.

Does it work on phones and tablets?

Yes. It fully supports touch and multi-touch, and automatically lowers particle density on smaller screens for smooth performance.

Are there sound effects?

Yes, optional. Launch and explosion sounds are synthesized with the Web Audio API and are off by default — toggle the sound button to enable them.

What firework shapes are available?

Peony, ring, willow, heart, palm and crackle. You can let shapes be random or lock a single one in the settings panel.

Is anything sent to a server?

No. All physics and rendering happen locally in your browser using Canvas 2D, so nothing is uploaded.
