Free Celestial Starfall Alert for Follows, Subs, and Raids

A stream alert needs to register without taking the canvas hostage. Celestial Starfall handles that with a transparent overlay that drops a celestial rain across whatever scene is live, fires on follows, bits, subscribers, and raids, and clears without leaving a hole in the gameplay underneath.

It is free with Meld Studio. No watermark, no paywall, no usage limit.

How the alert lands

The animation is a soft cosmic rain. Stars stream down across the full canvas, layered on a transparent background so the alert reads on top of gameplay, a Just Chatting cam tile, or a starting soon scene without covering it. The effect runs for long enough to register and clears on its own, leaving the scene the way it was.

A single overlay handles four event types: follows, bits, subscribers, and raids. The visual is consistent across all four, so a viewer landing during the alert reads it as the channel saying thank you regardless of which event fired. That consistency is what makes the alert layer fit a celestial-themed channel: every event speaks the same visual language.

Events from Twitch, YouTube Live, Kick, and TikTok Live all trigger the same starfall. Meld signs you in once and the alert listens to every platform you stream to at the same time.

Tuning the trigger

The default trigger covers the four standard event types. Meld Spark, the AI overlay editor included with Meld Studio, lets you narrow or expand that list with a plain-English prompt. A request like “Only trigger on subscriptions and make the stars larger” rewires the overlay immediately. You can also swap the palette, slow the fall speed, add a sound on each landing, or attach the raider’s name in a glowing constellation font when a raid lands. Changes persist between sessions, so the alert looks exactly the same the next time you go live.

Who this is for

Streamers running a celestial, nebula, or cosmic-themed channel who want their alert layer to fit the rest of the scene rather than break it. The transparent canvas also makes it a fit for streamers who want a more atmospheric alert than a hard popup, regardless of theme. The starfall reads as a moment that belongs to the channel rather than a generic notification.

Adding it to your stream

Download Meld Studio and Celestial Starfall is one drag away from being live. If you already run OBS, the free Spark Plug for OBS plugin brings the starfall into your existing OBS layout as a transparent browser source, with the same multi-platform event support and the same Meld Spark customization in plain English.

Use cases

• Layering alerts over a busy gameplay scene

  A solid-background alert covers what you are playing for the few seconds it stays on screen. Starfall is built transparent, so the cosmic rain drops over the gameplay underneath without blocking the moment that earned the alert in the first place.

• Tying alerts into a celestial-themed channel

  For streamers running a starlit, nebula, or cosmic aesthetic across starting soon, BRB, and main scenes, a generic alert popup breaks the visual identity. Starfall keeps every event inside the same celestial language as the rest of your overlays.
