See what’s happening. Visualize flag usage. Search for someone and easily put them in the flag.
01Developer Focused
Not just for your product team. Multi-context support lets you target attributes besides the user like: cloud region or availability zone, supporting database migrations or rollout a v2 swap-over.

Straight forward and usage based, you won't find better pricing out there. Developers deserve world-class tools without painful pricing.

Focus on your levers.
We'll take care of the rest.

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.

HuntClubMark FagaPrincipal Software Engineer
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.
