Getting Started

This page is an overview and a short guide on how to get started.

ConfigCat is a cloud-based service that lets you release features without code deployments.

You can use it with many similar techniques such as feature flags/toggles, canary releases, soft launches, A-B testing, remote configuration management, and phased rollouts. Configure your application and features even after deployment.

The birth of a Feature Flag

First, add a feature flag on the ConfigCat Dashboard, then you can connect your application to the ConfigCat service to access your feature flag.

Create a feature flag on the ConfigCat Dashboard

  1. Log in to the _Dashboard_
  2. Click ADD FEATURE FLAG and give it a name.

Connect your application

There are ready to use code snippets for .NET, Java, Android (Java), Kotlin, iOS, Dart (Flutter), Node, JavaScript, Python, Go, PHP, Elixir, C++ on the ConfigCat Dashboard, just scroll down to the SDK Key and steps to connect your application section.

All the ConfigCat SDKs are open-source and available on GitHub.

See the detailed Docs on how to use the ConfigCat SDKs.

Here's a short example to demonstrate the concept:

var configcat = require('configcat-client');
var client = configcat.createClient('YOUR SDK KEY HERE');

client.getValue('isMyFeatureEnabled', false, (value) => {
if (value === true) {
} else {
