Feature Flags without compromise.

To save you precious time and resources, we built the tool we’d want to buy.

Excellent CLI & Editor Plugins. Target cloud region or availability zone to support database migrations and tricky rollouts

01Fair Pricing

Use the language you want

Stay in Your Flow. Stay in Your Editor

Is this feature flag a zombie? Is it stale? Don't wonder, just hover over the flag to see realtime evaluation data.

Autocomplete flag names or create new flags right from your editor.

Testing flag behavior locally? Just click 'personal override' to toggle the flag just for you.

Developer-first from day one.

Give your engineers a developer experience that keeps them in their flow. Diagnose and fix production systems in an instant. Develop locally with our slick as hell editor tools.

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 find Prefab to be very developer friendly and engineering friendly. It's almost like a built by and for engineers, right? Which is funny because all other services are obviously built by engineers, but they don't feel that way. This feels like a very, successful balance and one that I appreciate as an 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.

Debug logging doesn't help if it's not turned on,

But it would be too expensive to have it on all the time.
