Seeking Baseball Scoreboard for MacOS

Can anyone point me to a baseball scoreboard for use in OBS Studio 28 for MacOS, preferably HTML CSS based and able to be updated remotely.

Here's an example of preferred style but willing to consider alternatives.

Did you ever find one?

This is a common request. Look through the Plugins and other Resources and find several.

I'd recommend UNO live overlays - https://overlays.uno/home
They have a rich library of existing overlays (including scoreboards of many kinds) that can be modified to fit your look and feel.
I'd all controllable online, and they even have a Stream Deck plugin for their integration.
On top of that, their free plan will take you a long way before you need to pull out your credit card.

HTH, Tom
