Used For

• +**Weekend deploys keep breaking your app** → Test new features on 5% of users, roll back instantly if things go wrong
• +**Every small change requires a full code deployment** → Toggle features on/off from a web dashboard in seconds
• +**Your A/B test needs different versions for different user groups** → Show the blue button to Americans, red button to Europeans, automatically
• +Client-side caching means unlimited flag checks after the initial download
• +Works with mobile apps, web apps, and backend services through simple SDK calls

Best For

• >Your new feature broke production at 2am and you need an instant rollback button
• >Rolling out changes to 10% of users first instead of praying nothing breaks
• >Your product manager wants to test features without bothering developers every time

Not For

• -Solo developers or tiny teams — the free tier covers most small projects, but you won't need the advanced targeting
• -Teams that rarely ship features or experiment — you're paying for switches you'll never flip
• -Static websites or projects without active development — requires SDK integration and coding

Pairs With

• *GitHub (where your code lives, but now you deploy without fear knowing you can toggle off broken features)
• *Datadog (to monitor what happens when you flip feature flags and catch issues early)
• *Slack (where your team celebrates successful rollouts instead of panicking about broken deploys)
• *PostgreSQL (to store user attributes that determine who sees which features)
• *Stripe (to gate premium features behind subscription tiers without code changes)

The Catch

• !You still need developers to add the SDK calls in your code — it's not truly "no-code" for setup
• !Usage pricing based on config downloads can add up if you're not caching properly
• !Your app needs internet connection for the initial feature flag fetch (though it caches locally after)

Bottom Line

Stop deploying code just to flip a switch — control who sees what features from a dashboard.
