Features

Everything you need to ship fearlessly

Powerful feature flag management with the developer experience you deserve.

Instant Updates

Change flags without redeploying your app. Updates propagate immediately.

Client-Safe Flags

Control which flags are exposed to client apps. Keep sensitive flags server-side.

Simple SDK

One provider. One hook. No ceremony. Works with React, React Native, and Expo.

Powerful CLI

Manage flags from your terminal. Create, toggle, and list flags without leaving your workflow.

Usage-Based Pricing

Pay for requests, not users. No per-seat nonsense. Scale without surprises.

Kill Switch

Disable features instantly if something goes wrong. Sleep better at night.

Developer Experience

Integration in minutes, not days

Our SDKs are designed to feel native to your stack. Type-safe, tree-shakeable, and built for modern frameworks.

  • TypeScript-first with full type inference
  • Server & client components support
  • Automatic flag updates with WebSocket streaming
  • Offline mode with local evaluation
