Streamlabs

Streamlabs is a streaming tool with alerts, donation widgets and overlays built in rather than assembled from separate services.

Those on-screen elements — follower alerts, donation notifications, goal bars — are what a stream needs beyond the video itself, and having them integrated removes the configuration work of wiring them together.

It is built on OBS and adds this layer on top, so the underlying capability is the same while the setup is more opinionated.
