Thanks for the shout-out! One of the cool things about LaunchDarkly is that you can use it out-of-the-box without needing to provision any additional infrastructure.

By default, the SDKs use server-sent events to push feature flags to an in-memory store. If you need persistence + strong consistency, you can back the SDK with Redis as well.

Disclaimer: I'm one of the co-founders of LaunchDarkly.

first I'd seen LaunchDarkly.. looks very nice.

o/t, was checking out your blog and saw that you launched Outlier; congrats! I was a big fan (and heavy user) of Flurry.. excited to see what comes of this.
