How it works

Three steps to production-ready flags

From flag creation to real-time control — no configuration hell, no vendor lock-in.

01

Define your flags

Create feature flags via the CLI, API, or dashboard. Set targeting rules, default values, and rollout percentages per environment.

terminal 
# Create a flag from the CLI
flagify flags create new-checkout \
  --type boolean \
  --project my-app
02

Deploy safely across environments

Promote flag configurations from staging to production with a single command. Each environment is fully isolated — no cross-contamination.

terminal 
# Promote config to production
flagify promote \
  --from staging \
  --to production
03

Control behavior in real-time

Toggle features, adjust targeting, or roll back instantly. No redeploy needed. Changes propagate to all connected SDKs in milliseconds.

terminal 
# Toggle a flag instantly
flagify flags toggle new-checkout \
  --env production \
  --enabled false

Core capabilities

Everything you need to control releases

A focused set of primitives that cover the full lifecycle of feature management.

Feature flags

Toggle features on or off for any environment without redeploying. Boolean flags, multivariate flags, and percentage rollouts out of the box.

User targeting

Serve different experiences based on user attributes. Target by plan, role, geography, or any custom property you define.

Remote config

Change application behavior at runtime. Update thresholds, limits, and content without touching code or waiting for a deploy.

Environment control

Manage flags across development, staging, and production independently. Promote changes safely through your release pipeline.

Infrastructure

Built for production from day one

Flagify is not a prototype wrapper around a key-value store. It is secure, isolated, multi-tenant infrastructure designed for teams that ship to production.

Scoped API keys

Every key is scoped to a specific project and environment. Keys are generated using HMAC-SHA256 and can be rotated instantly.

JWT authentication

All API requests are authenticated with short-lived JWT tokens. No long-lived secrets in your codebase.

Environment isolation

Staging, preview, and production are fully isolated. Flag state, targeting rules, and keys never bleed across boundaries.

Multi-tenant architecture

Workspaces, projects, and environments are logically separated at every layer. Your data is isolated by design.

Audit trail

Every flag change, config promotion, and key rotation is logged with who, what, and when. Full traceability for compliance.

Edge-ready evaluation

Flags are cached locally by the SDK and updated via streaming. Sub-millisecond evaluation with zero network dependency at runtime.

Why Flagify

The feature flag platform that stays out of your way

Most feature flag tools try to do everything. Flagify focuses on what matters: reliable evaluation, clean targeting, and a great developer experience.

01

Simpler than the rest

No 200-page setup guides. No enterprise onboarding calls. A clean API, clear docs, and a CLI that gets you from zero to flags in under five minutes.

02

CLI-first workflow

Create flags, promote configs, and manage environments from the terminal. Designed for developers who work in code, not dashboards.

03

Predictable pricing

Three plans, transparent limits, no per-seat surprises at scale. You know exactly what you pay before you commit.

04

Built for real environments

Staging, preview, production — each environment is fully isolated with its own flag state, keys, and targeting rules. No shortcuts.

Developer experience

Integrate in minutes, not days

A clean SDK that stays out of your way. Initialize once, evaluate flags anywhere. No complex setup, no background daemons.

flagify.config.ts 
import { Flagify } from '@flagify/node';

export const flagify = new Flagify({
  projectKey: 'my-project',
  publicKey: process.env.FLAGIFY_PUBLIC_KEY,
  // Flags are cached locally and synced
  // in real time via SSE
  options: { realtime: true },
});
checkout.ts 
import { flagify } from './flagify.config';

function getCheckoutVariant() {
  const variant = flagify.getValue<string>(
    'checkout-redesign'
  );

  return variant === 'v2'
    ? renderCheckoutV2()
    : renderCheckoutV1();
}
