Define, manage and control them in one UI to enable dynamic application behavior and A/B testing.
While feature flags started as simple boolean toggles, modern applications need much more. FlagFlow supports a rich variety of flag types to handle any use case.
True/false toggles for simple feature switches
Numeric values for limits, percentages, and thresholds
Text values for API endpoints, messages, and configurations
Complex objects for advanced configurations
Our intuitive wizard guides you through flag creation with clear steps, validation, and helpful hints.
Autocomplete, validation, and suggestions help you follow consistent naming patterns.
Organize flags in a tree structure for logical grouping, easier navigation, and team-based management.

Move configurations between environments with confidence. Export, backup, restore, and migrate your flags with granular control and comprehensive validation.
Generate type-safe interfaces automatically from your flags:
// Auto-generated TypeScript interface
interface FeatureFlags {
darkMode: boolean;
maxUsers: number;
apiEndpoint: string;
uiConfig: {
theme: 'light' | 'dark';
beta: boolean;
};
}
// Type-safe access
const flags: FeatureFlags = await getFlags();
if (flags.darkMode) {
applyDarkTheme();
}Validate flag data at runtime with automatically generated Zod schemas:
import { z } from 'zod';
// Auto-generated Zod schema
const FlagsSchema = z.object({
darkMode: z.boolean(),
maxUsers: z.number().min(1),
apiEndpoint: z.string().url(),
uiConfig: z.object({
theme: z.enum(['light', 'dark']),
beta: z.boolean()
})
});
// Runtime validation
const result = FlagsSchema.safeParse(flagData);
if (result.success) {
// Type-safe flag usage
console.log(result.data.darkMode);
