Caster Overlay Script for Streamlabs Chatbot


My homie The_Alcoholic_Ninja built a really cool script for Streamlabs Chatbot called Caster Overlay Script that allows you to have an animation pop up on your stream when shouting out other streamers. Once setup, you can set a command that you, your mods, or whoever else you want to have use it, that will pull a streamers logo and url and display on your stream with a variety of animations to choose from.

To install:

  1. Download Caster Overlay Script
  2. Ensure Python is installed (If you do not have Python installed click here)
  3. Open Streamlabs Chatbot
  4. Go to scripts tab
  5. On top right, click import and select the
  6. Right click on Caster Overlay script and click “Insert API Key”
  7. Right click anywhere in scripts tab and select “Open Scripts Folder”
  8. Open CasterOverlay folder and copy index.html file path (Example: C:\Users\username\AppData\Roaming\Streamlabs\Streamlabs Chatbot\Services\Scripts\CasterOverlay\index.html)
  9. Open OBS and create a new browser source and input index.html path as a local file.
  10. Next you to configure the script. Start by getting your twitch Client ID and inputting into the “API Key” section of the script.
  11. Choose your command to activate script, colors, transitions and even add sound effects by inputting a sound file path.
  12. Before you can test out your new cool script make sure that you have it enabled in Streamlabs Chatbot.
  13. That’s it!

    The idea of this script seems really neat. I’ve been trying to get it setup but for some reason it’s not working. It’s imported into the bot, I’ve inserted the API key, and ensured it’s active. For some reason the overlay never seems to trigger. I have a feeling it has something to do with the Twitch API Client ID (not something I’m use to using before). Are we supposed to go into the Twitch developer portal, create an app and grab that client ID?

      I managed to get it working. The button in the script ‘copy overlay to clipboard’ gives a url ending in index.html however the file should be overlay.html. Thanks for the great script!!

        Glad you were able to get it working! And thank you for that typo… good catch… it was something I added after I got it set up but I will change that for the next version.
