Everything You Need
Feature Flags are great, but you shouldn't have to settle on capabilities or need a mortgage.
Prefab is the bits you actually want at a no-brainer price.
With no skimping on enterprise features like audit logging, shared segments, multi-context and visualizations.
No More 🧟 Feature Flags
Can we delete this flag yet? In data you should trust. With Prefab editor tools just hover and see the evaluation details from production. It's time to kill some 🧟 flags.
The hover shows you current values and rollouts in all environments & the last 24 hours of evaluation history so you know what's fresh.
A Better Developer Experience
Create or toggle flags right from your editor and never mistype a feature flag name again.
We've also made sure that you can toggle the flag in development without changing your fellow developers' environments with personal overrides.
Flow and Feedback
Setting a flag is one thing, confidence that it's working in production is another.
Real time visualizations chart on how your flags are being evaluated in production.
Something look suspicious? Dive deeper and break down the charts by which rule matched so you know exactly what's going on.
Power Features
If you're going to adopt a Feature Flag tool, you should pick one with the creature comforts that make it pleasant to use.
Prefab let's you search for a user by any attributes right in the UI. No more copying user IDs around, just search for them by name and assign the variant for any of your flags.
Robust and Resilient
The resiliency story you need,
the speed of real time updates you want,
an audit log for every change,
and speedy client libraries.
