ConfigCat SDK for Unreal Engine provides easy integration for your application to ConfigCat.
ConfigCat is a feature flag and configuration management service that lets you separate releases from deployments. You can turn your features ON/OFF using ConfigCat Dashboard even after they are deployed. ConfigCat lets you target specific groups of users based on region, email or any other custom user attribute.
ConfigCat is a hosted feature flag service. Manage feature toggles across frontend, backend, mobile, desktop apps. Alternative to LaunchDarkly. Management app + feature flag SDKs.
The underlying ConfigCat C++ SDK uses these wonderful libraries: hash-library, nlohmann-json, z4kn4fein-semver.
