I Built a Simple Feature Flag Service Because I Was Tired of Being Afraid to Deploy

*The Problem That Kept Me Up at Night
*
You know that feeling when you're about to deploy to production? That pit in your stomach wondering "what if this breaks everything?"
I was there every single time. Even for small features, I'd spend hours second-guessing myself. Sure, I could use other platforms, but for my projects and small apps, they felt like bringing a bazooka to a water balloon fight - powerful but overkill (and expensive).

So I Built FlagSwift
After one too many "please work" moments hitting the deploy button, I decided to build something simpler.

What it does:

✅ Simple dashboard to create and manage feature flags
✅ React client with a clean FlagProvider component
✅ Per-environment targeting (dev, staging, prod)
✅ Per-user targeting (gradually roll out to specific users)
✅ Team collaboration (invite your devs to test together)

What it doesn't do:

❌ Require a PhD to set up

Quick Example

import { FlagProvider, useFlag } from '@flagswift/react-client'; function App() { return ( <FlagProvider apiKey="your-api-key" environment="production" userId="user123"> <MyComponent /> </FlagProvider> ); } function MyComponent() { const isNewFeatureEnabled = useFlag('new-checkout-flow'); return ( <div> {isNewFeatureEnabled ? <NewCheckoutFlow /> : <OldCheckoutFlow /> } </div> ); }` 

Try It Out

Application: FlagSwift
Install: npm install @flagswift/react-client

It's free while in beta

What I'm Looking For:

Honest feedback from real developers:

Would you actually use this? (Please be brutal - I can handle it)
What am I missing? What features would make this a must-have?
What SDKs should I build next? Next.js? Node? Vue? Svelte?

Why I'm Sharing This?

Because I think every developer deserves to deploy without fear. And if this helps even one person sleep better after hitting deploy, it's worth it.

Also, I genuinely want to build something people actually want to use, not just something I think is cool. So please, tear it apart and tell me how to make it better.

Try it out and let me know what you think!
