StreamElements

StreamElements gives a stream its furniture. Overlays and alert graphics are built in a browser and pulled into OBS as one browser source, so nothing lives on your machine and the same setup follows you to another computer. Around that sit a chat bot, a loyalty points system and a tipping page.

It competes most directly with Streamlabs and works across YouTube, Twitch and other platforms at once. The cloud-hosted approach is the real difference between them.
