You’ve probably heard the term feature flag, maybe in a pull request review, a deployment postmortem, or a job description. The concept sounds simple: turn features on and off without redeploying code. But once you start working with them, you realize there’s a lot more to it than a boolean in a config file. They fundamentally change how you ship software.

This guide explains what feature flags actually are, how they work under the hood, when to use them, when not to use them, how to test them properly, how to manage them across teams, and how to avoid the organizational problems that turn a helpful tool into a maintenance burden.

Releasing new features in a mobile app can feel like walking a tightrope, especially when updates require going through lengthy App Store and Google Play review processes, and users still need to download the new build. That's where feature flags come in. They are software development tools that give developers the power to toggle features remotely, test new functionality safely, and control rollouts without shipping a new app version.

This guide shows you how to use feature flags in Flutter (Dart) with ConfigCat, focusing on best practices, manual polling, offline support, and real-world examples.

Hey, Rustaceans! We developed the Rust SDK in response to a feature request from one of our customers, OneSignal. When we heard about their needs, we rolled up our sleeves and released the Rust SDK two months later. With it, you can manage feature flags like a pro—whether starting a new project or optimizing an existing app. It allows you to toggle features on and off without redeploying your code. That's right—no more redeploys every time your boss changes their mind about a button color!

With ConfigCat's feature flags, you can gradually roll out new features, rigorously test them (in a controlled environment, of course), and make changes on the fly—all directly from your dashboard! Let's dive into why this is a game-changer for your development workflow.

Are you a game developer seeking an efficient way to roll out, manage, and control features in your games? Look no further. With ConfigCat's Unreal Engine SDK, you can seamlessly add feature flags directly into your Unreal Engine projects, allowing you to decouple feature releases from deployments. This not only gives you greater flexibility but also helps streamline your feature development process from start to finish. How does it work in practice? Let's dive in.

At ConfigCat, we always prioritize our customers' feedback and requests to ensure we provide the best experience possible. That's why we took action on a user suggestion to support browser extensions based on the Manifest V3 platform.

We're excited to announce the release of our ConfigCat SDK for Chromium Extensions. This SDK is a specialized fork of our JavaScript SDK. Designed to allow for easy incorporation of our feature flag services into browser add-ons, it features a specialized cache implementation leveraging the chrome.storage API, which enables proper SDK functionality.

Suppose you have two variations of a software product, but you're not sure which one to deploy. That's the problem A/B testing solves. And in mobile development, running a clean A/B test is harder than it sounds because you can't just toggle a server-side flag and move on. You're dealing with bundle updates, app store review times, and users who haven't updated in months.

This guide shows how to run a proper A/B test in a React Native app using ConfigCat feature flags for the rollout and Amplitude for analytics. By the end, you'll have a working implementation, a real results-reading framework, and a clear picture of what to do when the test is over.

We're proudly announcing our 16th SDK release! ConfigCat's C++ SDK is now generally available. This SDK is a native C++ implementation of ConfigCat's feature flag management service. It is designed to be lightweight, easy to use, and easy to integrate into your C++ projects.

React Native is a popular framework created by Meta (formerly Facebook) that simplifies the development of cross-platform mobile applications. In short, React Native lets you build mobile apps using JavaScript, which gets automatically transpiled into native code for Android and iOS.

If you've ever wanted to release a React Native feature to users without waiting for app store approval, you're not alone.

In this guide, you'll learn how to use feature flags in React Native to control features without redeploying your app, using ConfigCat.

Our customers are at the heart of everything we do at ConfigCat. We take pride in knowing customer satisfaction is our top priority because we know that many of our competitors do not place the same value on customer experience as we do.

You asked. We listened!

We're excited to announce that ConfigCat now has an official React SDK.🥳🎉 The React SDK has been a highly requested feature by our customers, and we're proud to knock it off our checklist. The React SDK provides customers with a more modern, first-class React integration support when integrating ConfigCat with their React applications. We hope our customers share our enthusiasm for it.

Let's play with a hypothetical scenario where you've built a Kotlin-based mobile application, and you'd like to customize the overall user experience based on specified criteria. You've got a perfect idea, but then this question pops up everywhere: Now what? Folks, allow me to introduce you to the concept of feature flags in Kotlin.
