Testimonials

We switched to Prefab from LaunchDarkly and couldn't be happier. The clients are user-friendly with a powerful UI, and their dynamic logging is a game-changer. We can toggle log levels across our entire stack [Rails, Node, and Typescript], saving costs by enabling low-level logs only when needed.

I'm running a startup, but that doesn't mean I don't want the dynamic control over my configuration that I had when I was on a team with 100 engineers. Prefab gets this and gives me the core dynamic configuration and feature flags that can be my foundation as we scale.
