Virtual fireworks you can control
Use the full simulator to launch bursts, trigger finales, choose scene presets, and switch between manual and automated show modes.
Pyro Lab / online firework simulator
Online firework simulator for quick virtual fireworks
Launch fireworks in your browser, run quick show scenes, and switch between chemistry-inspired flame colors such as sodium yellow, barium green, copper blue-green, and strontium red.
- No download or account is required; the simulator runs directly in the browser.
- The full simulator includes sound, fullscreen mode, scene presets, finale bursts, and performance controls.
- The effects gallery previews browser fireworks, confetti, spark, snow, star, and celebration background effects.
- The Creator makes fireworks text images and celebration posters with templates, Remix, share links, and PNG export up to 4K.

What this page is about
A browser-based fireworks simulator
Pyro Lab is an interactive online firework simulator. The main experience is a canvas where you click or tap to place fireworks, choose color presets, and run a short virtual show without installing anything. A separate effects gallery shows browser fireworks and celebration effects such as confetti bursts, spark fountains, snow scenes, star fields, and event backgrounds.
Flame-test color presets
Color options are named after common flame-test elements, giving the simulator a clear link to sodium, lithium, copper, barium, strontium, magnesium, and other metal colors.
Fireworks effects gallery
The Effects page is for comparing browser fireworks effects, confetti explosions, side confetti, spark fountains, snow scenes, star fields, and abstract visual backgrounds.
Fireworks text creator and 4K export
The Creator page turns fireworks and celebration effects into custom images with editable text, templates, Remix, share links, JSON export, and PNG export sizes up to 3840x2160.
Designed for desktop and mobile
The core interaction is simple: click or tap the sky. Detailed controls stay available without taking over the whole fireworks canvas.
Fireworks text creator
Create fireworks text images and celebration posters
The Creator page adds a design-tool layer on top of browser fireworks and celebration effects. Type custom text, choose a fireworks, confetti, fountain, snow, stars, or spark-trail effect, apply a theme, then use templates or Remix to generate new visual variations.
Finished designs can be exported as PNG files in current view, HD, 2K, 4K, square, and story formats. Creator settings can also be exported as JSON or copied as a shareable link.
Open fireworks text creatorCreator templates
Start from Birthday, New Year, Love, Congrats, Launch Day, Neon Logo, Snow Night, or Fire Festival.
Remix button
Generate fast variations by randomizing effect, theme, density, glow, and light links while keeping your text.
4K PNG export
Export celebration posters in 3840x2160, 1920x1080, 2560x1440, square, story, or current-view sizes.
Shareable settings
Copy a Creator link or export JSON so a custom celebration design can be opened or recreated later.
How it works
From color choice to fireworks burst
The page content, navigation, and simulator controls all describe the same product: a free online firework simulator with virtual fireworks and chemistry-based color presets.
- 01
Choose a firework color
Start with a metal preset such as sodium, lithium, copper, barium, strontium, or magnesium.
- 02
Click or tap the sky
The canvas places each virtual firework where you interact, so the show feels direct and tactile.
- 03
Open the full simulator
Use sound, fullscreen mode, scene presets, finale bursts, and performance controls for a larger show.
Browser fireworks effects
A practical effects gallery beside the simulator
The main simulator is built for interactive virtual fireworks: tap the sky, change flame-color presets, start an auto show, or trigger a finale. The Effects page has a different purpose. It previews browser fireworks effects, confetti effects, spark scenes, and abstract visual motion in a controlled canvas.
These effects are useful for UI celebration moments, landing-page backgrounds, event screens, and visual experiments. They are not presented as real-world pyrotechnic physics, and the page does not claim that arbitrary text or logos can reliably explode into readable fireworks.
Open fireworks effectsFireworks preset
A muted browser-safe fireworks preset for automatic visual bursts.
Confetti effects
Continuous center confetti, random confetti explosions, and side confetti cannons for comparison.
Atmosphere effects
Hexagons, star fields, color circles, light links, and tunnel motion for non-realistic celebration scenes.
Mobile controls
The effects panel can be collapsed on mobile so the canvas remains the main interactive surface.
Color reference
Firework colors based on flame tests
Real fireworks often use metal salts to produce color. Pyro Lab turns that idea into simple simulator presets, so users can compare lithium red, sodium yellow, copper blue-green, barium green, strontium red, and magnesium white in one place.

Pyro Lab is a small browser experiment: part fireworks toy, part flame-color reference. It is meant to feel quick and a little tactile, not like a full production suite.
The canvas is the main control.
Start the simulator, then click where you want the burst to appear. The bottom panel is there only when you want to change the show.
The colors have a chemistry hook.
The presets are named after metals used in flame tests, so the color picker has a little bit of science behind it without turning the app into homework.
It stays intentionally simple.
No account, no editor timeline, no setup flow. Open it, pick a color, make a few bursts, move on.
