Get started
Sign up or start from the CLI:
npx @reflag/cli new
Then flag your feature:
import { useFlag, ReflagProvider } from "@reflag/react-sdk";
const MyFeature = () => {
const { isEnabled } = useFlag("my-new-feature");
return isEnabled ? "You have access!" : null;
}
const App = () => (
<ReflagProvider
publishableKey="{YOUR_PUBLISHABLE_KEY}"
company={{ id: "acme_inc" }}
user={{ id: "john doe" }}
>
<MyFeature />
</ReflagProvider>
)
Or compare Reflag with LaunchDarkly, PostHog, or homegrown solutions.
