Stream add-ons are individual graphic assets designed to upgrade specific parts of your live stream setup without buying a full overlay package. Each category on this page covers a different piece of your stream's visual identity — animated alerts that fire when viewers interact with your channel, countdown and count up timers for your pre-stream lobby and break screens, stinger transitions that mask scene changes with a brief animation, Twitch and Kick panels that brand your channel page, sub emotes that give subscribers exclusive chat icons, and sub badges that reward long-term subscriber loyalty. Every add-on is a standalone instant digital download, compatible with OBS Studio, Streamlabs, StreamElements, and all major streaming platforms.

Add-ons are built for two types of streamers. First, streamers who already have an overlay package and want to fill in the missing pieces — maybe you have overlays but your alerts don't match, or you've never set up a stinger transition or break timer. Second, streamers who want to build their setup one piece at a time rather than committing to a full bundle upfront. Either way, every add-on in each collection is designed to match the corresponding overlay packages and stream bundles in the Stream Designz catalog, so buying within the same theme keeps every element of your stream cohesive.

An ultimate stream bundle gives you every visual asset for your stream in one download — overlays, alerts, panels, timers, a stinger transition, and channel assets — all matched to a single theme at a lower combined price than buying each piece separately. Add-ons let you pick and choose exactly what you need, which is ideal if you already have parts of your setup covered or want to mix specific pieces from different categories. If you're starting from scratch or want the most complete setup in the fewest steps, the Ultimate Stream Bundles collection is the better starting point. If you're filling gaps in an existing setup, you're in the right place.

Browse each collection above to find the right add-on for your stream. Every design is available as an instant digital download — ready to drop into OBS or Streamlabs in minutes.
