What builders tell us after they experience the VB magic ✨
Developer experience
I can't go back to building voice apps with vanilla LiveKit.
Client actions
And then we saw something you had called client actions. And frankly, we fell in love with that. That was the single biggest blocker which we were facing with all other previous applications. The ability for the agent to do things, to control the system or your applications. So that basically cut down most of our efforts.
