Bits Fireworks
Every cheer launches fireworks from the bottom of the screen — more bits, more and bigger bursts.
A alert box overlay for Twitch and OBS
Bits Fireworks is a free Twitch bits alert that turns every cheer into a fireworks show. Rockets launch from the bottom of the screen, one for every 100 bits up to 40, and bigger cheers get bigger bursts in the classic Twitch cheer-tier colors. The cheerer's name and amount glow in the sky above.
It fills the whole 1920 × 1080 canvas with a transparent background, so it sits over your gameplay or camera scene. Change how many bits each rocket costs with the per option, and cap the show for huge cheers with max.
- One firework per 100 bits, adjustable
- Bigger bursts and tier colors for bigger cheers
- Cheerer name and amount shown in the sky
- Launch and crackle sounds, adjustable or muted
- Smooth at any OBS frame rate
