Free Biplane Raid Alert Overlay That Shows the Raider and Viewer Count

A raid lands, a small alert flashes for a couple of seconds, and half the people who just arrived never learn who sent them. Propeller Raid gives that moment some room. A vintage biplane flies across your stream towing a banner, and the banner says who raided you and how many viewers they brought.

It is a free raid alert, and it does one job well.

How it works

The alert reacts to the Raid event. When a raid comes in, the biplane crosses the screen three times with the raiding channel’s name and viewer count on its banner, then flies off and leaves your scene clear. The plane is a 3D model, so each pass reads as an object moving through space instead of a flat graphic sliding by.

There are no chat commands to learn and nothing for your viewers to type. It sits in your scene until a raid arrives, which makes it a good fit for streamers who do not want another thing to manage mid-stream.

The overlay pulls events from every platform you stream to. Twitch, YouTube Live, Kick, and TikTok Live raids all trigger the same biplane, so multistreamers get one consistent welcome instead of four separate setups.

Why streamers use it

A raid is the best introduction a small channel gets, and most of it is lost when the alert is easy to miss. Three passes give new viewers time to see the banner, read the name, and look around at your stream before the plane leaves. It also gives you something to point at when you say thank you.

For streamers who raid out at the end of a session and get raided back, it turns a quick shout-out into a short, memorable moment. Because the banner carries the viewer count, the raider sees their group acknowledged on screen.

Who this is for

Streamers who regularly host or receive raids, community-minded channels that like to welcome other creators, and anyone who wants a raid alert with more character than a text pop-up. It works in a full-screen game scene or a quiet Just Chatting layout, because the plane crosses the screen and then clears out.

Adding it to your stream

Download Meld Studio and add Propeller Raid to a scene. If you already run OBS and would rather stay there, the free Spark Plug for OBS plugin brings the same alert into your existing OBS scene. Either way there are no scripts to write and no monthly fee, and one sign-in covers raids across Twitch, YouTube, Kick, and TikTok.

Use cases

• Welcoming a raid without stopping the show

  When a channel sends you its viewers mid-game, you rarely have a free second to read out names. The biplane does the introduction for you: it crosses the screen with the raider's name and the number of viewers they brought, so you can keep playing and thank them when there is a lull.

• Making a raid feel like an event for the new arrivals

  People who land on your channel from a raid are deciding whether to stay. Three slow passes of a banner-towing plane give them something to watch while chat catches up, and it shows the raiding streamer's name big enough for everyone to read.
