Stop Paying Too Much For Feature Flags

Everything you need, without stupid pricing
Try It Out
Prefab feature flags user interface

Feature Flags without compromise.

To save you precious time and resources, we built the tool we’d want to buy.
00Observability
See what’s happening. Visualize flag usage. Search for someone and easily put them in the flag.
01Developer Focused
Excellent CLI & Editor Plugins. Engineer focussed context: target cloud region or availability zone to supporting database migrations or rollout a v2 swap-over.
02Fair Pricing
Straight forward and usage based, you won't find better pricing out there. Developers deserve world-class tools without painful pricing.

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'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.

Also We Fixed Secret Management

Share Secrets between developers, projects & languages.

CLI based. Zero-knowledge. No extra cost.

And You Can Change Log Levels Instantly

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

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