About this mode
A simple way to run a realistic firework show online
Firework Simulator Pro is built for people who want fast, believable fireworks in the browser without learning a complex editor. You can launch manually, run auto mode, or turn on finale mode for denser bursts. The controls are intentionally practical: adjust shell behavior first, then tune quality so the show stays smooth on your device.
If you want more playful, chemistry-inspired presets, switch to the classic simulator.
