StreamElements

I've been using this for a while. I've since switched to using Streamlabs OBS instead.

Pros:

Has a pretty nice leaderboards feature

Cons:

Not a new product, better alternatives.

some of my gaming world coming into my tech world here but Stream Elements is fantastic! I've set this up for my hyper-minimal streaming but set it up and use it daily for a streamer friend of mine. Their Discord is fairly active and devs are pretty responsive for support issues and for code help. The overlay builder is really nice and works well for my non-dev-streamer-buddy. Chat bot commands are almost all there, and the remote api fetch works well with their commands too. Only a few things I had to custom build that they didn't already have baked in but otherwise a great setup for streamers.

Any plans for Facebook Live integration?
