It only took three months but I’m happy to share that BetaBuilder is now on the Mac App Store! You can purchase it here:
Yes, I did decide to charge $1.99 for the app. That decision won’t impact the source code availability – it’s still on GitHub and will remain there. The $2 bucks is a way to support the project and say thanks if you feel so inclined.
Anyway, this was a long time coming and I’m happy to see it up there now!
