How to add it to OBS, Streamlabs or Meld

  1. Set it up above, then press Copy link.
  2. In OBS Studio, click + under Sources and choose Browser. In Streamlabs Desktop, add a Browser Source; in Meld Studio, add a Browser layer.
  3. Paste the link into the URL box and set the width and height shown under the link.
  4. Leave "Shutdown source when not visible" off. If it is on, live alerts and goals stop whenever you switch scenes.
  5. Drag it where you want it and resize it with the red handles. The background is transparent, so only the alert shows. Tick Control audio via OBS so the alert sound gets its own volume slider in the mixer.

It also works as a Twitch Studio, PRISM Live or vMix browser input. Gear that pairs well: a Stream Deck or a free OBS install. Disclosure. Your settings are saved in this browser, so you can come back and change them; after changing settings, paste the new link into the source.

What triggers an alert

EventTwitchKick
New sub and resub (with months and message)Yes, including Prime and tier 2/3Yes
Gift sub and gift bombYes; a bomb of 20 shows one alert, not 20Yes
Bits (with message)YesNo
Raid / hostYes, with viewer countYes (hosts)
Follows, channel points, Twitch Charity donations, hype trainsYes, after you connect Twitch (one click, read-only)No

YouTube: add your YouTube channel and Super Chats, Super Stickers, new members, member milestones and gifted memberships all alert, worded the YouTube way ("became a member", "sent a Super Chat"). Tips: Ko-fi, Streamlabs and StreamElements tips alert too, with the tipper's message shown and read aloud when text-to-speech is on.

Alerts queue up and play one at a time, so a gift bomb followed by a raid shows both in order. Each one plays its sound, shows your text with the viewer's name in your accent color, throws confetti, and, if you turn on text-to-speech, reads the viewer's resub or Bits message aloud before moving on.

Time on screen = max(your seconds, time to read the message aloud) Gift bomb of N: one alert, and the N individual gift notices that follow are folded into it Text-to-speech: messages over 200 characters are cut, letter spam is shortened, slurs are never read

Example: a viewer gifts 5 subs, then a 42-viewer raid arrives. The overlay shows "GenerousGifter gifted 5 subs!" with a fanfare and confetti for 7 seconds, then "BigStreamer is raiding with 42 viewers!".

How it hears your chat: the overlay connects to your Twitch or Kick chat the same anonymous, read-only way a logged-out viewer does. It never posts, needs no login or token, and sees subs, gift subs and Bits as they're announced in chat. Commands only work for you (the broadcaster) and your moderators.

Chat command (broadcaster and mods)What it does
!skipEnds the current alert and its speech
!alerts pause / !alerts resumeHolds alerts in the queue, for a serious moment, and lets them play again
!alerts mute / !alerts unmuteTurns sound and speech off and on
!alerts clearEmpties the queue

Frequently asked questions

Is this a free Streamlabs alert box alternative?

Yes. It runs as a browser source with no account or login, and covers subs, resubs, gift subs, gift bombs, Bits and raids on Twitch, plus Kick subs, gifts and hosts.

Can it show follower alerts?

Yes. Twitch doesn't announce follows in chat, so connect your Twitch account once at /connect/twitch, then tick "Use my Twitch connection" here. A follow-bot flood can only queue 5 follow alerts at a time.

Does text-to-speech work in OBS?

It uses the voices installed on your computer through the browser's speech engine. Test it with the Resub button in the preview, and in OBS tick "Control audio via OBS" to hear it in your mix.

Will a 50-sub gift bomb spam 50 alerts?

No. The bomb shows one alert with the total, and the 50 individual gift notices that follow are folded into it.
