For Twitch streamers
Twitch Raid Alerts sounds, goals and TTS for incoming raids
When another streamer raids you, their whole chat arrives at once. Blerp can mark the moment: a raid goal that fills on its own, a raid sound your viewers set off, and an alert that plays a sound, a TTS line or a video with the raider's name the second the raid lands.
What a raid alert is
A raid alert plays on stream the moment Twitch sends the raid: a sound, a TTS message, a video, or an alert box with the raider's name and how many viewers came along. Without one, a raid is a system message in chat that is easy to miss mid-game.
Blerp alerts run in one browser source in OBS or Streamlabs Desktop, the same source as your follow and sub alerts, so a raid alert is one more alert in the list, not another tool.
Start free
A raid goal
Put a goal on screen that counts incoming Twitch raids and fills up on its own in OBS. Goals are free.
Raid sounds viewers play
Viewers with the Blerp extension play an air horn or a crowd cheer from under your stream when raiders pour in, with Bits, Blerp currency or points they earn by watching. Free.
Sound channel point rewards
Five Blerp sound rewards are free on Twitch, so your community can fire the raid sound themselves.
The raid event alert, part of Blerp Unlimited
Under Alerts, Raids is its own group. An alert there plays for every raid, or only for raids above a size you pick, so a raid of a hundred gets a bigger welcome than a raid of three.
One alert can hold a sound, a TTS line that welcomes the raider by name, a video and an alert box together, and you can give the same alert several variations so it doesn't repeat.
Set up a raid alert
- 1
Link Twitch
Open Integrations on Blerp and link your Twitch account, or sign up with Twitch.
- 2
Make the alert in the Raids group
Open Alerts, press New alert under Raids, and pick what plays: a sound, a TTS line, a video or an alert box, or several together.
- 3
Choose when it plays
Press Edit trigger. Keep any raid, or set a floor like 10, 25, 50 or 100 viewers. Make a second alert with a higher floor for big raids.
- 4
Test it, then add it to OBS
Press Test in browser source, then paste Blerp's browser source into OBS. Real raids play through the same source.
Raid alert sound ideas
- An air horn or a crowd cheer: loud, short, and everyone knows what it means.
- The raiding community's own meme. Keep a few ready for the streamers who raid you often.
- A TTS line that says who raided and how many came, so you can thank them without reading chat.
- A video for the biggest raids only. Set it to play at 100 viewers or more.
- Keep small-raid sounds under a few seconds. A long alert for three raiders gets old fast.
Raid goals and subathon time
Goal per raid
A raid goal counts each incoming Twitch raid toward a target. Free, and it updates on stream by itself.
Time per raider on a subathon
A Blerp subathon timer can add time for each viewer a raid brings, so a big raid buys a big extension. The timer is part of Blerp Unlimited.

Can big raids get a different alert?
Yes. Each raid alert has a viewer floor, so one alert can cover small raids and another, with a video, can play at 50 or 100 viewers and up.
Does it work in Streamlabs Desktop?
Yes. Blerp alerts play through a browser source, which works in OBS, Streamlabs Desktop and any app that takes browser sources.
