Introducing Flagify

Feature flags are not a new idea. The concept has been around for over a decade. So why build another tool?

The problem we kept running into

Every team we have been part of reached the same inflection point: the codebase grows, deploys get risky, and someone says “we should use feature flags.” Then one of two things happens:

  1. The enterprise path — you evaluate the big-name vendors. The product is powerful, but the setup takes weeks, the pricing is opaque, and you need buy-in from procurement. By the time you are flagging features, the urgency has passed.

  2. The DIY path — you build a flags.json file or a database table. It works for a month. Then someone needs targeting. Then someone needs environments. Then the config file is 400 lines of YAML and nobody wants to touch it.

We wanted something in between.

What Flagify is

Flagify is a feature flag and targeting platform built for developers who want to ship safely without adopting an enterprise platform.

Here is what that means in practice:

  • Install in 2 minutes — npm install @flagify/node, initialize with your project key, evaluate a flag. That is the entire setup.
  • Typed SDK — TypeScript-first, with generics for value flags. Your editor knows your flag types.
  • Real targeting — rules based on user attributes, percentage rollouts, reusable segments. Not just on/off.
  • Environments — dev, staging, prod with independent flag states and API keys. Promote configs safely.
  • Streaming sync — flags update in real time via SSE. No polling, no stale data.
  • AI-native — first-class integrations with Claude Code, Cursor, GitHub Copilot, and Windsurf. Manage flags without leaving your editor.

What Flagify is not

We are not trying to be a product analytics tool, an experimentation platform, or an enterprise governance layer. Flagify does one thing well: it evaluates feature flags quickly and reliably based on rules you define.

If you need a 30-person approval workflow before toggling a flag, we are probably not the right tool. If you want to ship a feature to 5% of pro users in production and see if anything breaks — that is exactly what we built for.

Try it

The free plan includes unlimited flags and 50,000 monthly evaluations. No credit card required.

We are just getting started. Follow the changelog to see what is next.
