Firework Engine

Stream overlays with lift-off

Live fireworks for creators who want spectacle without setup pain.

Firework Engine gives streamers one persistent OBS overlay, saved launch layouts, trigger integrations, and room to grow from simple celebrations into custom creator-built fireworks.

Get Started
Beginner Mode OAuth login + one overlay URL

Sign in, link your platforms, drop the overlay into OBS, and fire simple effects quickly.

Advanced Mode API, bots, webhooks, WebSocket

Use Streamer.bot, custom automations, and named firework triggers without changing the overlay source.

One overlay, always mounted

Your OBS source stays live. Firework Engine refreshes patterns, themes, and layout changes silently in the background.

Themed overlay sets

Switch between saved scenes like Halloween, Birthday, or Holiday without rebuilding your stream layout.

Launch zones and scene assets

Use PNG or GIF overlays plus saved launch locations to create mini scenes that hint at premium choreographed shows later.

Built for stream integrations

Begin with native login and guided setup, then grow into bots, automation tools, webhooks, and mobile operator controls.
