I have another question. Launchdarkly has realtime feature means, if I change the features flag value in their dashboard it's changed immediately in the client side. Is there same feature in Growthbook? if yes then how to achieve that?

We don't have a built-in way to do that right now. Someone built a proof of concept using lambda and websockets.

Where I can get that that example code or sample code?

Thanks 🙂
