About this template

A alert box overlay for Twitch and OBS

Cozy Cat Sub Alert is a free cute Twitch sub alert for lo-fi, cozy and chill streams. A sleepy cat naps on a pastel cushion, wakes up when someone subscribes, has a big stretch and holds up a sign with their name, all to a soft little pop.

Gifted subs and gift bombs get the sign too, and alerts queue up so a burst of subs plays one by one instead of piling on top of each other. It sits at the top centre of a 1920 × 1080 canvas, so you can drag and resize it anywhere in OBS.

OBS setup

Add Cozy Cat Sub Alert to OBS in under a minute

  1. Copy your overlay URL.

    Replace YOUR_CHANNEL with your Twitch username: https://www.overlaify.com/overlays/cozy-cat-sub-alert?channel=YOUR_CHANNEL

  2. Add a Browser source.

    In OBS Studio, click + under Sources, choose Browser and name it “Cozy Cat Sub Alert”.

  3. Paste the URL and set the size.

    Paste the URL, then set Width to 1920 and Height to 1080. Leave custom CSS empty — the background is already transparent.

  4. Test it before you go live.

    Add &test=1 to the URL to fire simulated events, then remove it once it looks right. Tick “Control audio via OBS” if you want the alert sounds on their own mixer track.

Subs, resubs, gifted subs and gift bombs come from Twitch chat with no login. Streamlabs Desktop, Meld and Twitch Studio work too — add it wherever they accept a browser source or URL.
